I am yet to spend $200 on deepseek this year. Not sure what kind of usage can justify $200/month of either openai or anthropic, i'm not even talking about $500. Deepseek is faster, IMO intelligence difference is negligible and it so much cheaper that i no longer care about how much i use it. I never hit any daily/weekly quota or anything like that while working or tinkering. At this point i am OK with being 6 months behind the "frontier", purely on bang-for-buck basis and who cares which shadowy government gets my data.
So I took Deepseek V4.1 Flash for a spin maybe 2 weeks ago now (before Luna 6 and Sol 6 were announced), and I racked up $100+ in about 2-3 days. It was pretty great, but it uses way more tokens (TPS is fast, but it's way more tokens per turn) than Sol 5.6 which I found to be about it's equivalent at the time (on medium or high, with DS on max). My cache rate was around 98-99%.
It would definitely cost me more per month than a x20 ChatGPT or Claude plan, probably around $400+ was my estimate at the time. This was with Fireworks (ZDR) which has since increased their prices (and got slower!).
That being said, very impressed with the model, and looking forward to what comes next. As the frontier models become less subsidized, the open models will become more appealing.
P.S. There are subscription plans for open models, but I've found most of them to be extremely slow, have model throttling (only so much of model X), and also very sketchy about training and data retention. No thanks! If you want to share your data, just use Muse Spark contributor. Seems impossible to beat that on price per task if you don't mind feeding your data to the Meta machine (spoiler: I won't).
There's a bunch of skepticism in the replies but I ran over 100 tasks against DeepSeek 4.1 Flash and Sol (among others) and I can confirm, it is in fact a little smarter than Sol and a little more expensive than Luna. https://slopcop.com/power-ranking?pricing=api
I also spent $280 on DeepSeek doing the tests (direct to DS, not OpenRouter). I suggest that if you can't conceive of anyone spending $200 on DeepSeek, you're not being ambitious enough!
Is slopcop your domain, because that is awesome. Wishing you great success with it.
It is. TY!
Were you using OpenRouter? I've used 1.8bn tokens in the past week from DeepSeek themselves and 99.2% were cache hits. Total cost was $18.13 usd.
For readers wondering, OpenRouter isn’t capable of caching as effectively as DeepSeek is because they will, for instance, switch inference providers in the middle of a session.
The way I use openrouter is I find a model/provider combination I like then pin all requests for that model to that single provider.
If you disable all other providers but DeepSeek in your OpenRouter guardrails, is that effectively the same thing?
How do you do this?
provider: { order: ['deepinfra/turbo'], allowFallbacks: false, },
https://openrouter.ai/docs/guides/routing/provider-selection
What pests said. And you can make a preset and pass "model": "@preset/deep-seek"
Fireworks directly. At the time they were the best value of cost, speed, ZDR. They got slower on me though, but I think they are retooling, so maybe things have or will get better again. I think fireworks is primarily for when you want to do your own training on top, which I wasn't doing.
Same experience. I often see people say how little they spend on DeepSeek v4.1 flash, but when I put 60 bucks into my account, it was gone in a few days of non-exclusive use. I'm actually curious what the difference is. I used it through pi and opencode, but the harness seemed to have no obvious impact on usage.
This is my experience, too. It's a great model, but it burns tokens if you use it heavily for work on complex domains.
Edit: others have noted the provider and harness matters. My experience is with opencode.
How have you spent hundreds of dollars? I’ve only spent 11 and I’ve been using it for four months!
How on earth you can do 100 dollars in 2-3 days with DeepSeek? I have 7 agents in omp running 24/7 every day. I use maybe 10-15 dollars a day. A rarely see a session going over 2 dollars. My maximum is maybe 3.5 dollars and that session took three days.
What harness you are using?
pi. I wasn't even going that hard. I checked the logs for Sep 18 and I did just shy of 3b input with approx 98.5% cache and 5.8m output, which cost around $35. Most of the was a Rust code review exercise with 1 driving agent and a varying number of subagents (up to 6 some times). I do the same with with Sol med/high driving and Luna x-high reviewing and get at least as much done if not more in a day, but I'd use up two x20 weekly allowances for the week. Worth noting that token cost isn't super meaningfull on it's own, because DS is super token heavy (but also great at caching) compared to Sol. (my stats show DS uses 3x the tokens as Sol)
The shape of my work changes obviously, so it'll vary, sometimes more, sometimes less. For example, fixing all of the bugs and defects I found that week was 2-3 times the effort and chewed through my ChatGPT allowance, but I had banked resets...
Also worth noting that codex models have been kind of all over the place recently with their usage... and it looks like costs are changing again.
You might be overusing subagents. Especially with a chatty model like DS, you’ll be wasting millions of tokens on re-discovering the project and facts instead of actual reasoning.
What are those agents doing? I am out of the loop. Bitcoin mining? Blogging? Reddit bots?
I have deepseek agents doing email responses, with real tools (think running quotes, gathering info, scheduling things) and running business processes that used to be done by $35/hr administrative type people. And the capabilities are expanding every day as I learn how to build scaffolding around the model.
[delayed]
I am a tech lead for a useful but non-essential PaaS my company subscribes to. Their product manager occasionally sends me clearly AI-authored emails. I ignore them. I am a believer in the usefulness of AI, but nothing says I don’t care more clearly than sending me slop.
I can’t overstate how bad of an idea I think using an AI for customer interaction is.
Work for my company. Research, code, analysis.
I’m lost when I read these sort of comment chains. Free Gemini works just fine for me. Maybe it’s because I don’t use it for programming? How many programmers really exist out there? Surely it can’t support the weight of investment that exists in AI already. It’s just such a small pool of the human race.
First, they come for the programmers, and next the mathematicians. Then it will be the biologists, lawyers and doctors. Humanities will stake it out a little bit longer because AI isn’t human, but AI companies would be dammed if they don’t try. Eventually, with advancements in robotics, stabs at increasingly more physical sciences will also be attempted. Eventually, AI will have its hand in the pie of all knowledge work, if it is possible. Not to mention all the roles like tech support and customer service. Once they have gotten as far as they think they can go, they will try to turn up the prices. However, they might struggle to do so as models are becoming a commodity. This is why they are arguing for regulation and stating that only they can tame these beasts.
same, used a wrapper around cc and i was spending up to $30 a day with basic stuff
Maybe CC does something that breaks the cache? I cannot recommend Oh My Pi enough. Every default is galaxy brained, and it plays incredibly well with deepseek flash 4.1. My favorite coding harness rn for sure.
I found omp used quite a bit more tokens than my fairly basic pi setup... but most of those tokens would be cached with DS V4.1, so maybe worth if there are gains elsewhere.
It’s easy to hit your quota. “Speed up the compilation time of this C++ codebase. Feel free to use several subagents to search through the files in parallel.” That’ll cost you about $200 for a codebase of ~1,000 files.
Subagents are like trading derivatives. You can lose as much as you want.
What bothers me about this whole AI tokenomics situation is the lack of transparency. OpenAI and Anthropic have to perhaps be the most opaque companies in existence wrt their offerings. There's like a thousand variables that they can change on the backend at the push of a button which can wildly swing API spends within the same model (partly also due to the non-deterministic nature of LxMs, but still), and there's no objective way to measure them other than vibes.
When the regulations do arrive, I think they should really focus on AI companies and API providers being more transparent wrt how they're billing their customers. Because right now, it's a totally vibes-dependent and a mess.
And it's all measured in "intelligence", a completely meaningless term. For coding i'd be much more interested in how much context actually works, what the complexity of algorithms it can understand and create is, for what languages. How much it manages to follow existing structures or that is just adds ad-hoc machinery to pass the test, etc etc.
A smaller model in the same generation will never be the same as a bigger one, assuming this is a smaller model, and the same generation, as naming implies, it will not be comparable, it might be on the benchmarks, even on the benchmarks that matter, but the whole story should also give the drawbacks.
It's still insane that they stopped showing you all the tokens you pay for. They could inflate the billed reasoning token amount by a lot before it would raise any eyebrows.
Internet Ad business has been like that for a long time with bot click & Co.
Ain't that the truth.
In Search Advertising, the amount you pay (under GSP Auction) is a function of your pCTR. And guess who determines your pCTR? The Search Engine itself! :-D
Totally hand-wavy and non-objective ... just like how employees are billing their employers.
It's all Gacha for business.
Yeah, you might get away with a singular 'wrt' with some consternation, but two?
> Subagents are like trading derivatives. You can lose as much as you want.
Excellent pithy warning.
Sadly this is true - for individual folks on the lower end of the spend spectrum.
But there’s a point on that spectrum where the ability to run multiple experiments in parallel, even with a significant amount of (one time) wastage, is overall more cost effective than the alternative.
Afaik there is just pay-as-use with Deepseek
Why use subagents at all
Preserve context in the lead chat - let the subagents fill up their own contexts then only return the necessary information.
Why not just have an agent that can branch its context?
Why hire a junior developer if you have a perfectly competent senior developer already on your team?
You can do a code review on a "less capable" model that costs less, and the key model gets its output / summary, then you can have that model build a plan, and feed it to cheaper models. It's a more efficient approach than just running everything through Opus, and now that Sonnet is a lot better I'll probably use them more frequently, one thing to note is don't ask it to spin up endless subagents, I'd cap it to 2 or 3 at a time, otherwise, yeah you'll hit your limit extremely quickly.
Because two agents are faster than one.
The models get dumb as context fills. Subagents allow them to accomplish a task with minimal context rot. You can also use cheaper models for subagent tasks
Time is money. Parallelism is very helpful optimising one to get the other.
Money is money too. Increasing contexts costs non zero money, even with cache hits. Also context rot is a problem that subagents help with
This truism is intuitive to everyone but always funny to me how everyone never has any time, needs to save time, needs to hire staff workers for every mundane job and robots can't come soon enough… all so we can binge watch Game of Thrones and 90 day Fiancé.
And watch 10 hours of football on Sunday for our DraftKings bets.
Money is also money, which anyone who makes heavy use of parallel subagents will quickly learn.
> Time is money. Parallelism is very helpful optimising one to get the other.
Parallelism is fantastic when it actually speeds up the entire pipeline, but in my experience most people's jobs (at least the ones for which AI is currently relevant) involve a lot of overlapping "hurry up and wait" branches that drastically blunt the real benefits of that sort of parallelism.
There may be specific situations where it makes sense to do it, but just immediately going full gastown on anything AI related seems like such a giant waste to me, of both money and finite world resources.
I have $200/month Claude continuously making money to pay for itself and for $200/month Codex, and then I use the $200/month Codex for actual projects
There's a difference between "write this function for me" coding agents and "build this prototype from end-to-end". If you're doing the former, deepseek is fine. If you're doing the latter, it's not gonna work, and that's where the extra intelligence is most valuable.
I'm mostly using deepseek 4.1 flash via openrouter, the way I'm doing stuff is:
1. write a sketch of a spec by hand
2. have the llm review the document and question me until it can generate a spec
3. review the spec and revise where needed
4. have it write an implementation plan
5. another round or revision/review
6. executing the plan step by step through the plan, plausing between each step to see if we are still on course and if the decisions it made track with my understanding of what we are doing.
I've been working for a couple of hours tonight, the total cost of the session is €0.6.
it's not the build this thing end to end, but also not quite write function x for me. It is still a lot of manual review, but I find I really need it to even discover what I actually want to build. I just cannot imagine building something in a single shot and getting something that actually has value (unless it is basically a clone of an existing thing). To me the whole value of ai right now is that it's now very cheap to build custom software that exactly matches your preferences.
This was my experience 3 months ago. I had an Android app that interacted with a Bluetooth device that I wanted to reverse engineer and build my own Linux app for it. DeepSeek was struggling really hard. Claude did it end to end after 3 or 4 prompts. To be fair, I was using a web interface for DeepSeek and the CLI for Claude; maybe that makes a large difference.
build this prototype from end-to-end, is this how people build serious software with AI?
You're not gonna get something that's ready to ship, but as a first pass to get something running yes. Let's you explore far more ideas with only a few hours of agent time.
I started KeenLore (an emotive audiobook creator) that way. I gave it software specifications, languages, JSON schema definitions, container requirements, hardware configuration (8GB NVIDIA T1000 GPU, 96GB RAM), and zero user interface mockups. For the second round, I asked it to build a completely independent, re-entrant, and data isolated demo system on top of the web application. The demo application included voice generation using one of its voice designs. Here's the output:
https://www.youtube.com/watch?v=WAeHgE94rVo
The system performs quotation attribution on my local hardware for my near-future, hard sci-fi novel (having nearly 500 quotations) with over 97% accuracy.
The initial prototype was developed quite quickly, but numerous successive iterations were required to fix numerous gaffs by Opus 5 (because it doesn't actually _understand_ what it takes to make general-purpose audiobook narration software).
I don't think most prototypes are serious software.
This is how ChatGPT, Cursor apps are built. They spent so much money on PR stunts, but "thousands of agents" can't make an app that doesn't freeze on each keystroke. Not even talking about user-friendly ui
Weird, ChatGPT has always worked really well for me.
Early on their software was like this, the original ChatGPT desktop app was basically unusable and full of memory leaks that would tank the software. They’ve long since fixed that though
The new ChatGPT desktop app is a dumpster fire though, it can’t even scroll properly when streaming the answer.
For a prototype or a 1 or 2 use tool, yes, this is exactly how serious people are building software.
Oh buddy you have no idea what a good plan and agent harness can do with deepseek…
I am doing mostly hardware drivers recently, it works fine for complex work.
"build this prototype from end-to-end" works fine with DeekSeek V4.1 Flash, the problem occurs if you're not only building a prototype but want a finished product.
I spent the weekend trying Deepseek 4 Pro on a Linux porting project and it led me down a complete rabbit hole where Linux wouldn't even boot by the end of the weekend. Waste of $120. Switched back to GPT 6 on Monday and Linux is booting again and I'm making progress.
The only thing I've found Deepseek and Kimi good for are security tasks that GPT refuses to do.
This is a summary of what Deepseek did and got wrong:
Lost the proven baseline: changed kernel source, configuration, compiler, RAM geometry, MMC width, and peripherals together. Matching an upstream commit did not preserve local boot fixes, making failures difficult to isolate. Misidentified an image: a file labelled “r18-known-good” actually contained the r23 parent bootloader. Filename-based reasoning replaced verification of the artifact’s identity and provenance. Shipped inconsistent boot contracts: flash-16b’s loader read too few kernel blocks. Fresh2 changed the device tree without updating the loader’s expected length and CRC, creating deterministic rejection before normal Linux handoff. Patched binaries without maintaining reproducible source: loader constants diverged from source, a separately compiled cache-flush length remained stale, and assembly used an oversized stage-two slot. Their causal contribution to hangs was not established. Overstated diagnosis: claimed failures were definitively in U-Boot, blamed compiler or IPU changes without controlled isolation, converted noisy observations into confirmed hangs, and neglected persistent journals as an alternative explanation. Mistook compilation for integration: framebuffer registration was incomplete, timing success handling was inverted, BT.656 selection was unreachable, encoder overrides were missing, and audio lacked software clock configuration. Misread hardware evidence: asserted interrupt-free PMIC operation, assigned RF to the wrong SPI controller, confused regulator identifiers with register addresses, and described repeated encoder writes as unique registers. Overclaimed results: treated kernel/probe indications as userspace success, presented earlier discoveries as new progress, and omitted failed flashing attempts from the final narrative.
> Deepseek 4 Pro
There's your problem, 4.1 Flash is significantly better and cheaper, to the point where the official DeepSeek API is going to (or already has, I forget) redirect requests for Pro to 4.1 Flash, and adjust billing accordingly too.
4 Pro is still offered by providers I'm sure, since it's open weight, so I can understand making that mistake.
That's an unfortunate experience. Think of v4.1 flash as actually v5.0 flash. It's night and day compared to the 4.0 flash (and 4.0 flash was unintuitively better than 4.0 pro). I would re-evaluate with v4.1 flash. I'm not saying it better than Sol or anything, but it's in the ballpark.
You mean 4.1 Flash which is the first great Deepseek? The one that actually surpasses Opus in my books now.
I've been trying to use DeepSeek V4.1 Flash more and been very impressed. My current (very rough) rule of thumb is that an Artificial Analysis score of ~40 is the crossover point for "good enough" for most of the things I need to do with coding agents.
47 is my crossover for serious things (e.g. Grok 4.7 is below the line and GPT 6 Sol is above the line). I mean, Opus 5.5 is way better, but GPT 6 Sol still gets the job done for anything that doesn't require design thinking.
Although I do think Luna 6 max is ok for some basic things, would never use it for coding myself.
What's the most important task you would/wouldn't trust with an agent below the line?
Had the same experience. I got rid of my pro sub of OpenAI. I’m really freaking impressed.
Where are you inferencing DS4.1 flash reliably ?
I use OpenCode Go. I've also used the DeepSeek provider through OpenRouter a bit in the past and it seemed solid.
The intelligence difference between models like DS4.1 and Sol/Opus is NOT negligible.
The premium price is only worth fo the hardest problems.
For CRUD shoveling, models like DS4.1 are enough.
And the intelligence gap between cheap and premium is closing, as can be seen from the title of this post.
The issue is once you solve the hard problems, the lower models start messing things up that were working and reverting all fixes for the hard problems. They'll just go off and do dumb stuff.
In the Artificial Analysis index, MiMo 2.6 Pro is smarter than GPT-Sol 6.1 Low at the same cost, and only slightly dumber than Medium. MiMo 2.6 Flash is marginally cheaper and smarter than GPT-Luna 6 Max. (There is no GPT 6+ Terra, which would otherwise be in that range.) These are not negligible or trivial results.
If both DS4.1 and Opus can complete the tasks you throw at it at good enough quality the differences are negligible.
Who cares if your car can go 200mph if all you need is 60. If my requirement is 60mph, I want a faster 0-60, not a higher top speed.
Opus 5.5: $4/$20
Deepseek 4.1: $0.02/$0.60
Just to illustrate how cheap the Corolla is in your analogy. Also Opus output would be $50 without competition.
Specially if using the 200mph car when you need it is just a /model away.
Or just a cheaper way to reach 0-60
A car that feels safe to be driving at 200 mph is going to feel more comfortable at 60 mph, compared to one for which 60 mph is at the very limits of its abilities. Analogies only go so far so I'm not sure there's anything to be learned from that though.
What do you do? I’m 200 bucks deepseek flash in about 2 months and it’s increasing
I use it as main Hermes model that orchestrates codex/droid harnesses with subscriptions for heavy dev work
I do have ChatGPT as main assistant that sets direction and delegation of projects to Hermes
At my increasing usage, kind of 200 usd subscriptions makes sense and max out on Luna max
I put 5 dollars at deepseek a long time ago, and somehow it has never been fully spent, can’t imagine anyway to spend 200$ on that thing
Recently, drivers for a bunch of obscure hardware. Lots of c\c++, that i am ok with but not enough to make hardware drivers (i am just impatient). Just using pi agent with a few plugins.
How complex are they? Drivers vs an entire application would be a big difference in token usage, and it could also depend on the type of work being done.
Complex enough where performance matters. I've done entire applications, client, server, infra and ci as an experiment with deepseek v4 pro a few months ago. Works for that too.
I've been using Claude Code at work and OpenCode for side projects for a few months. Every OpenCode model I've tried always felt subpar compared to Claude, but good enough. But it changed with DeepSeek 4.1 Flash, I've been using it for the past few days and I've come to forget I was not using Claude, it's a really good model and it's basically free for my usage (I used it almost all the weekend and spent ~$5)
I think the only answer to this is you're just not using agents enough, because even with the very cheap pricing, it's still easy to rack up a large bill.
A lot of people having different pricing experience. I think it’s important to understand that caching can differ, than if the agents spend waiting on code, or consume a lot of content. It depends on how you structure you codebase and how explorable it is, how much effort you set and probably some other issues.
For raw productivity most of what works is best and switching will cost you getting on use parity with other models, as you need to learn what they good at, potentially how the tool works and how to prompt it best.
For tasks that you implement in code, you should have benchmarks and evals.
That said for me was Luna a huge leap and 500+ of cost savings a month
I've spent $200+ on deepseek and this is for making a multiplayer FPS game. Trust me there are use-cases.
And no it did not deliver. A lot of it was re-done by Astra
> I've spent $200+ on deepseek and this is for making a multiplayer FPS game.
Why do you expect that $200 will give you that on ANY model? Multiplayer FPS games are very difficult to make, no AI will deliver that today.
The speed of deepseek is insane to experience after using claude code with opus for so long. Not only is the tps roughly 3x faster, but the round trip times are magnitudes faster.
You clearly haven’t used opus or astra or only had simple tasks. Such a difference maker
A bit tired of spending $200 out-of-pocket for openai. What do you use as harness? (for me the harness if half of the benefit... controlling my PC, working from phone, etc.)
I use Claude Code + eternal terminal + tailscale + tmux + some custom skills to get notifications through nfty.sh.
I get the same UX on every platform, works perfectly on very low bandwith environments such as in a cabin, in the subway or in the middle of nowhere.
I tried using other harness such as Pi and opencode but I did not like them. If Claude Code gets weird I can swap in an instant.
You just need to follow this guide and disable artifacts in Claude Code's config: https://api-docs.deepseek.com/quick_start/agent_integrations...
I’m curious about your use of Tailscale, is that for you to reach a local LLM remotely from anywhere?
I have a big beefy desktop at home which I ssh (using EternalTerminal instead of raw port 22) into. I built it last summer right before the prices got very expensive. It's headless so I use a cheap Macbook Air to connect to it at home and I use Termux on my phone to continue working from everywhere.
Dude prompt your agent to set up always on remote connections via systemd… then you can drive from Claude or codex mobile apps natively over their native hookup. Works great.
I don't want to rely on Claude of Codex mobile features at all. Also none of this works when you use third party LLMs which is what the current comment tree is about.
This. There's so many better ways to drive a fleet of agents this way than using "remote" features of which I don't trust, anyway.
https://omp.sh/ has amazing defaults and it sips tokens. Works really well with DeepSeek V4.1 Flash.
Use the model through a fast and reliable provider such as Fireworks directly, skip OpenRouter.
Did you ever try pi by itself? For those new to the pi ecosystem - any rationale to go with pi vs omp?
It's like choosing between vim and helix. I started my career with vim in the early 2000's, customized the whole thing and had my config in a version control.
Then I installed helix and I just use it without config.
If you like configuring things take pi, if not omp is pretty much great defaults.
I have a server living in my home office, always on. I have a tmux session on it with vanilla Codex and Claude Code CLI, I can via my Ubiquiti network stack wiregaurd in to this box anywhere on the globe with just my laptop. Works super well for me. I also have some cheap shelley power plugs that I can use to cycle my PC’s power state if needed.
This is basically my setup but I'm using tailscale and zellij. I don't have any contingency plan in place for my power or home internet going down though..
OpenCode works nicely for me. You can connect it to the DeepSeek platform with an API key.
I use pi.dev, it is pretty minimal, but you can extend it however you want since agent has access to it's own documentation.

Where do you do your inference?
Are you just using it directly from them?
Kind of ambiguous without saying token amounts and cost.
Opus 5.5.is crazy good. I ask it to do things and it just writes the code to do it.
I just ran a huge text/image extraction grudgematch against all the current inexpensive models except gpt-5.5/5.6/6 (due to some issues with openrouter and bugs in my code) and DS4 ranked very poorly. Accuracy winner was Gemini 3.8 flash with minimax M3 and qwen 3.8 placing, and the chinese models beat the incumbent (Gemini 2.5 Flash) on cost whilst keeping like 95% of the accuracy.
I haven't used deepseek for anything else but the above results make me question its overall capability. Meanwhile qwen3.8 has continued to impress.
API pricing?
It's trivial to hit that kind of quota if you're trying to execute on major projects. Especially as you start having dozens or hundreds of subagents investigating, prototyping, and working on different things.
There was a model called Astra-Minor, found in the files a few days ago. I assume Sol 6.1 is this, as a last minute panic rename due to Sol 6 being underwhelming while Opus 5.5 turned out really strong. I can't really explain releasing Sol 6 in any other way, especially mere days ago.
I don't understand why they didn't call 6-Sol just 6-Terra. It was 5.6-Terra level pricing with a perf jump.
I don't understand any of this naming man. It just gets more confusing.
I like it. It's cool and better than Opus, Fable, Sonnet etc.
Like who can figure out the ordering? With Luna < Terra < Sol < Astra it's obvious at a glance.
I propose for some third company to name after monsters: Cyclops < Minotaur < Ettin < Cerberus < Hydra < Kraken < Nyarlathotep (the AGI singularity stage)
> With Luna < Terra < Sol < Astra it's obvious at a glance.
It.. is?
[delayed]
It’s not… why do I need to translate from Latin (or wherever these come from) to understand them? Opus, Sonnet, and Haiku do the same thing, and are widely known words. Not to mention all LLMs do is generate tokens; I prefer the homage to writing over a space reference.
Boy wait till you find out where "opus" comes from.. Do you realize how many words from Latin you used in that comment?
When was the last time you heard anybody say "opus" or "sonnet" before this?
Also it implies that "haikus" are inherently inferior to longer texts which may be kinda frown-inducing..
it really isn’t
clear would be something like
piss-cheap - it’s-alright-i guess - okay-relax - ouch-my-wallet
yes, each of these things are larger than the other
If that holds then the ultimate model must be called Urmom
and wth is an "astra"?
My brain immediately translated "Luna -> Terra -> Sol -> Astra" to "Moon -> Earth -> Sun -> Galaxy", an overall growing of size. While sure, "astra" doesn't directly translate to "galaxy", it's the base of the word "astronomical" and "astronomy".
I feel like people who don't get it immediately are just being deliberately obtuse.
I don't doubt that you feel that way, and there's no way I can really provide you any evidence. But I wasn't trying to be obtuse.
"Ad Astra" my guy. "To The Stars"
Many of which are thiccer than our beta ass sun
Pretty badass name tbh
Bigger => Bigger, makes sense to me.
Maybe if English is your first language it does.
There is also more room upwards. Galaxy? Quasar? Filament?
I mean, Haiku < Sonnet < Opus < Fable/Mythos makes just as much sense. They're larger and larger works.
Many people would get confused on the order of Opus, Fable and Mythos. In my mind, they are even from different groups; fable is a synonym forba fairytale (perhaps with songs), mythos is communicating importance and status instead of a size, while opus is the only one which in my mind communicates a big size. "What did you think about the Tolstoy's book? It was not a book, but a real opus, a tedious, incomprehensible, sluggish monumental opus."
Waiting on Limerick to drop.
opus fable sonnet haiku is way more obvious than luna terra sol astra imo
"When in doubt, baffle them with b*llshit"
Terra is the "missing middle" model and had no positive brand recognition. Sol was for intelligence, Luna was for efficiency. Luna max was cheaper and smarter than terra light and sol light was better than terra max.
Because they asked the model what it wanted to be called?
I mean, when I upgraded my pipeline from terra to sol saying "it's the same price basically!" I was excited. Probably would not have felt as excited if it was just a version bump.
Not sure that's why they did it. But that was my experience.
Was it a last-minute panic, or just OpenAI releasing an update when the had a bit more training under their belt to make 6.1-sol a whole lot better? Either way, I'm extremely pleased and will be giving this model a shot.
That seems likely, in the API GPT-6.1 Sol requires reasoning, just like Astra, whereas GPT-6 Sol (and Luna) allow "none"
Theo dropped their Sol 6.1 video and he says he can't tell you, but, shows enough to make it pretty clear. https://youtu.be/vu8X3YroB-w#t=5m30s
The smoking gun is how much slower than Sol 6 this is. It's not a retrain.
Sol 6 was pretty good the first 4 days or so of it's release. Then it was probably dialed back to a lower effort level and it became really bad.
> Cached input costs just $0.10 per million tokens—95% less than standard input pricing and 50% less than GPT‑6 Sol’s cached input pricing
This is the actual big announcement. 50% cheaper cache than GPT-6 Sol will get you far more mileage on Codex.
> 50% cheaper cache than GPT-6 Sol will get you far more mileage on Codex.
Cache doesn't help you much when you are compacting every 5 minutes...
I was shocked at how quickly I ran out my $100/mo subscription with a single agent (sol medium).
If you run out of sol medium with $100 you're doing something wrong. Astra destroys your usage, I get 1 day of usage with Astra, but 6 sol is almost unlimited and I only use xhigh.
It’s only nearly unlimited if you haven’t just used a banked reset. After a banked reset your weekly usage gets cut by about 80% (not the week you need to wait to get your normal limits back though). ChatGPT has given me a really good reason to cancel.
yeah I use sol constantly and have done maybe $15 of spend in the past week. it's solid and cheaper. this is at least 4-5 investigations, prs, whatever per day.
"You're holding it wrong." Is hardly a retort from a real paying customer having problems with their paid services.
This is why these companies are struggling to make money, they're chastising their customers just like they've been chastising the human race.
> "You're holding it wrong." Is hardly a retort from a real paying customer having problems with their paid services.
It's very appropriate in the cases when you're holding it wrong. The fact that you're paying doesn't mean that you can't make mistakes or waste resources.
If you're compacting every 5 minutes, you have a workflow problem - period.
No LLM will be cost effective if it's compacting this often. You have to find a way around it.
Context window is only 275k or something. And honestly compaction is not that bad in Codex. I often don't even notice I went through 5 compactions in a session.
Sounds like that's the problem then, 275k is a tiny context window. I regularly have sessions that go to 450k or even up to 700k for an unattended overnight Claude Opus session.
Apparently OpenAI makes you manually setup their 1 Million context window, and it seems to be only documented on X:
https://x.com/thsottiaux/status/2089082893804896524
There's at least a forum thread about it here:
https://community.openai.com/t/why-does-codex-report-a-258-4...
Same for me, I started wondering if maybe workflows using compaction instead of clear + markdown memory would be more efficient. Writing a plan or tasks to a file often has the next session repeat part of the exploration, compaction seems to keep most relevant context.
Your tool calls (MCPs?) are very likely too wasteful. Apply some filtering logic on the offending tool’s output. Either a wrapper CLI, or just tell codex how to filter.
you can actually leverage 400k and 1M contexts in codex with very little code changes to the harness. note that excess context past the.. 250k or 400k mark (i don't remember) is charged at 2x the price.
You have a lot of control over compaction, both directly by changing compaction settings, and indirectly by how you structure your codebase/docs so agents use less tokens.
Try Gemini. It’s so cheap I often use my personal AI Pro account for corporate work, and most of the time it doesn’t matter.
Gemini is dumb as hell though, it's not like for like
Gemini 3.8 Flash is actually pretty good.
cheerleader hallucinating agent. That's Gemini.
you can config codex to compact at a higher context limit
As a reference i burn 1% percent for every 40 minutes of sol on average
Exactly half as expensive as Opus 5.5 in every API pricing metric
And half as good. I didn't have great experiences with Anthropic models in the past, but Opus 5.5 seems to have turned a major corner. It is churning through tasks significantly more quickly and efficiently.
Suggest trying it out yourself: Ask for something difficult from GPT-6 Sol and Opus 5.5 and watch what each one does. The difference is stark.
Edit: Defining "difficult" as a complex coding or systems task (or even series of them in a single prompt).
> Ask for something difficult from GPT-6 Sol and Opus 5.5 and watch what each one does.
My side by side evaluation this week was to build a tool for mounting my app’s UI components in a headless chrome and feeding mock data into them, for the purpose of taking screenshots for help docs. Not super complicated, but a real task I needed done.
I gave the task to codex first, sol 6 xhigh. it took a couple back and forth prompts to define the project and then it worked for a bit and to took a couple more prompts before I decided it was good enough - not perfect, but close. It re-implemented some wrapper components in a simplified way that lost some of the UI, but it would work.
Opus 5.5 high took the same prompt with no back and forth, it just went off and one-shotted a tool that takes pixel-perfect screenshots of exactly what my app looks like.
You HAVE to have a set of personal evals for each class of task you want to use models against at scale so you can test plausible candidates and compare output on your work against your evals.
There is way too much subtlety in what does and doesn't work for a given problem, context/prompt, tool set and eval. I can tell you Fable is generally better than Haiku, but comparing similar tiers really does depend on your exact context.
> OpenAI models used to be the prototype for robotic text, but lately I've been finding them much more natural.
This was the biggest thing I noticed in the 6 models; their conversational prose is dramatically less grating.
This news and thread is about 6.1 Sol, not 6 Sol. You haven’t even had time to do a fair comparison yet.
> Suggest trying it out yourself: Ask for something difficult from GPT-6 Sol and Opus 5.5 and watch what each one does. The difference is stark.
Oh yes, I know GPT-6 Sol is ... quite not up to par. At least it's not as bad as GPT-5.6 Terra I suppose.
For my personal experience, antropic model have better user experience except for 4.7 and 4.8 though. 4.7 and 4.8 feels like expensive downgrade of 4.6 to me (I didn't know why these two should even exist)
However it's less willing to obey your instruction so it's less usable for general runtine flows.
For me Anthropic models from 4.7 to 5 including where bad and ate tokens like crazy. Task delivery was worse than GPT 5.6 and token usage was 2-3x higher.
Looks like 5.5 is the new 4.6
Are you comparing Opus 5.5 with GPT-6 Sol or GPT-6.1 Sol? Because they are different models.
I'm not an OpenAI simp, but how anyone can have any opinion on the performance of these models in less than a day - let alone a few hours - is beyond me.
I think it’s one of the reasons why you often see people decrying the lessening capabilities of the models a few weeks later, despite there being 0 proof of any changes, and evidence of the models staying the same from sites that track it.
They form these super strong opinions after a few prompts, then face reality over time.
People have been talking about how good whatever model is at “complex” tasks since the beginning, never mind that all of those models are now outperformed by Luna which many people consider unusable for complex work.
Try it, it's that good compared to openai current offering.
I get better results and usage our of my $20 claude sub than my $100 openai sub... it's that ridiculous
The usage allowances are now insane, like they were when the Max plans were introduced. The $100 plan is usable again for real tasks.
While I have no experience comparing this brand-new model, OpenAI themselves call it "near-Astra" intelligence. I set Astra and Opus 5.5 independently working on the same large research/coding task in an experimental project (doing NURBS surface modeling stuff). They had the same starting repo state, same task packet, same test suite to try to meet. I have the $100 plan in both.
Astra used 215% of a week's budget (I burned 2 free resets) and took 13 hours. Opus used 20% of a week's budget and took 20 hours. Both were asked to use lesser sub-agents for implementation grunt work at their discretion (Luna, Sonnet) as long as they manage and review the output.
The timing comparison is not that interesting because the wall-clock speed mostly reflects how often they ran the (large, slow) test suite, not their coding speed. Although in the past my gut feeling is that OpenAI models do generally respond faster.
The quality of their implementation was more interesting. There turned out to be a bug in one of the unit tests the agents were trying to pass. Opus interpreted the natural-language requirements from the task packet, found the test bug, and fixed it. Astra tried hard to solve the problem without altering the test suite. In practical terms Opus got much, much farther into a useful implementation. Astra was still stubbing out and faking critical parts of the implementation (B-splines) and since it ultimately couldn't pass the full test suite, finally gave up on its implementation. Astra wrote some useful tooling in the process of its efforts which I ended up integrating into Opus's version of the code, but otherwise its approach was behind.
Now, this is just one comparison in one domain, and arguably Astra's strict adherence to the tests as-given is a good thing. But Opus wasn't merely loosening the rules / moving the goalposts to pass, it spotted an actual bug, and was more successful at doing what I actually wanted. And the cost difference was Astra-nomical.
Out of curiosity for an interpretation free from my personal bias, I gave Astra a hint from Opus and permission to change the test in question, which it did, and got a bit farther, but still ultimately didn't produce a working implementation (to be fair, Opus's was not completely working either, but was closer). I then fired up fresh agents to review the two repos. Predictably, an Opus agent thought the Opus-written repo was the better basis to build on, and an Astra agent thought the Astra-written repo was the one to keep. They were not explicitly told which was which nor did the commit trailers say, but I assume they can tell. However, after doing this twice each, I saved the 4 review reports into another folder and did yet another meta-review of the 4 reports, so each would see the arguments and critiques both directions. In this meta-review both Astra and Opus converged on preferring the Opus implementation.
Astra doesn't just burn token at an insane rate, it is also strangely high maintenance when using it. Occasionally, you have to keep prodding it to keep working. Then at other times, it will disappear down some rabbit hole, trying to resolve increasingly hypothetical issues. It feels like you constantly have to keep it on track, while Opus is just churning through tasks.
This was a very interesting, informative, and well-written comment (and experiment). Thank you.
Yeah totally agree, people keep jumping in w/ strong views hours after release, eg: https://news.ycombinator.com/item?id=49045430
They’re comparing against the previous model, not the newly released one (6.1). Why do that on a thread about the new model, I don’t know.
benchmarks.
Only takes 5-10 minutes to test your favorite one shot comparison prompt.
Can you give an example? For me I find that one shot prompts are pretty good it’s only when working with large codebases and complex, multi prompt workflows, that I find the real limitations of models
Yeah the whole Pelican riding the bike is the best obvious one
If 5-10 minutes is enough, you need a more ambitious one-shot goal.
A pity I have to use claude code to try this, that I can't use the tools I know and love and have built around (opencode).
(I did use some CC for Fable when it came out, and it was... ok. Not the worst thing ever.)
Based on my benchmark[1] it is the same price as Opus 5.5 and just as capable.
Opus 5 scoring higher than 5.5 makes me question of the value of this benchmark to real world usage
Well, it is genuine.
Opus 5.5 fails the "understanding" tasks which Opus 5 passes. I feed it a script which takes two numbers and prints the max of the two numbers. Opus 5.5 thinks it prints 1/0 instead of the max numbers. Opus 5 gets it right.
Here are the outputs from both: https://gist.github.com/dom96/b5bce82b6e6c1ebd5271ed70ad941b....
Looking at that Opus 5.5 fails to deduce that the "hack statement" is actually an if statement in disguise, but Opus 5 gets this right. I feel like this is a pretty good test and shows Opus 5's greater intelligence.
cache is typically 10%, is this OAI setting a new level at half, 5%?
The backdrop being deepseek offering 1% (I remember it was ~1% when 4-pro first came out early this year - 4-pro is now removed) / 2% (current for 4.1-flash).
The GPT 6 release was ... not great.
Sol 6 was so bad that I switched over to Opus 5.5 exclusively.
Huge regression compared to Sol 5.6, often doing really dumb things. Same for Luna.
Even Astra is very unreliable for coding. Brilliant for vision, sometimes just great, but it also often does very stupid things.
I'm a bit sour on OpenAI right now and skeptical that 6.1 will be much different.
(Note: this is after preferring and shilling Codex/OpenAI models for the last half year)
I agree, and I haven't seen other people mention this! The benchmarks for GPT 6 Sol are great, but realistically it does not seem better than 5.6 Sol. 6-Sol is noticeably worse for code reviews (worse than Deepseek 4.1 flash), has implementation issues (requires more rounds of code reviews and fixes to get to a serviceable state). Opus 5.5 is much much better.
I've implemented multiple features side by side with Opus 5.5 and 6 Sol, and the Opus 5.5 results always have fewer high severity bugs and require fewer rounds of fixes to get it over the finish line.
If 6.1 Sol has actually matched Opus 5.5, I'd be very happy. However, benchmarks and real usage don't seem to agree in my own tests. So we'll have to see.
My experience as well.
For coding specifically, I've found 5.6-Sol > 6.0 Sol > Astra.
For modeling and artwork, Astra has been great routinely outperforming Kimi.
This is reminiscent to me of what Anthropic pulled back in February with their adaptive thinking rollout.
I can't wait for technology to catch up to a point where we can rid ourselves of this oligopoly.
That's my experience too. GPT-6 Sol tends to rabbit hole and over engineer things.
100% hard agree.
I used about 10 hours of Astra high-thinking compute time and it was a bad experience. Incredibly slow (prompts running for 30/40 minutes) to do simple things. As a result, Astra didn't get much done. It needs the same small implementation slices as GPT 5.5/others, but was much slower and didn't generate better results. (On a complex infra project/across a large codebase.)
It was absolutely terrible on a few long running tasks (~2 hours each). It really doesn't seem to be better than 5.5 at most programming jobs.
I'm on a $200 per month plan with OpenAI, which I am happy with and is definitely worth it. But I also use Google Gemini a lot (paid plan) and it is incredibly fast. Like I can't get coffee fast. Like I can't send an email fast.
OpenAI is making some excellent products for sure but I'm not going to keep using Astra unless I can get some benefit from it. It really seems like even the frontier models just aren't good at working autonomously on large codebase situations. Just because something compiles doesn't make it right!! In one of those 2 hour implementations, Astra engaged in *fucking EPIC cheating*. It wrote a probe/side app and then worked through the design there. Um, what? Not that it's invalid to do this but I actually have to test in the live codebase or I can't possibly say that something is working.
Just because you can, doesn't mean you should.
After seeing a number of hit or miss releases from both OpenAI and Anthropic my default is to stay put on what I’m using and then free ride on discerning eager adopters by reading their reviews. (Thanks!) Still on sol 5.6 with an occasional advice from Astra. Also I feel like I kind of get used to the models but maybe that’s just my imagination.
I'm in the same boat, I'll give 6.1 a shot but I'll probably hop over to Anthropic now that the $200 tier has equivalent weekly usage between the two of them.
Maybe OpenAI was the only one pacing the frontier.
I have likewise not been impressed with Astra 6 for most things. It is good, but Opus 5.5 seems just as good or better and I have had Opus 5.5 workers just... hammering since release and cannot spend all of my quota yet.
That's not been my experience. My experience with Astra (I use it at home writing Go and C) for coding has been fantastic. Opus 5.5 (I use it for work writing C#) seems faster than Opus 5, but it doesn't seem demonstrably better to my eyes and is still prone to word vomit.
Made the opposite experience. Astra was not good in writing go and c++ code. Had multiple OpenAi and Claude subscriptions and all our coworkers agreed. Switched back to Claude and the experience is so much better. Not vibe coding, but assisted coding with immediate feedback.
Same here. Astra has been the best thing I've seen. Astra on Low has been my favourite thing so far. Higher levels just mean more cruft, not useful.
gpt-5.6-sol is significantly better than gpt-6-sol. Not impressed with this new line.
Agree.
GPT 6 needs to be babysit, otherwise it starts doing ridiculous things.
I shilled so hard to a friend that he actually swapped decided to swap over to Codex. I feel a bit guilty now lol (tbh Astra is a great model, but 5.5 is just brilliant).
yeah i can relate, sol 6 is definitely dumber than 5.6, lazier too, i hope it's just roll out pains
How does this jive with the exponential growth claims? Theoretically sol models are better than the 4 series models I was using at the beginning of the year, but in practice the results don’t seem to be much better. They always nerf the models over the course of the release so it _looks_ like the next version is better but I haven’t seen actual capability growth since ~January, and I’m pretty sure that was all tooling/harness improvements.
They never nerfed any model after release.
The lackluster GPT-6 Sol has been superseded by this apparently much better 6.1 Sol within a week.
I am very skeptical of claims that old models weren't much worse. Compare this to February's GPT-5.3.
I am comparing to GPT-5.3 and 5.2, and I perceive that things have not been noticeably better since then. I also know that I can predict new model releases with high accuracy when my coding agent suddenly becomes regard-level at following instructions and completing simple tasks. This is how I knew 6.0 was about to be released - 5.6 suddenly got unusably bad.
I could point out that I said 6.0 seemed good only in comparison to nerfed 5.6 - people would say I’m just a RSI denialist - but now it is in vogue to accept that 6.0 sucked now that 6.1 is out.
How large of codebases are you working on? The models have gotten good enough to 1 shot stupid "trivial" throwaway integration projects with 0 handholding (was having RL'd garbage in late 2025), and I'm actually enjoying designing bounded greenfield personal software from scratch with Astra, in my experience. It's quite slow - 2 weeks of credits and constant talking and back and forth with Astra, but it doesn't feel annoying to talk to and is like an intelligent colleague maybe 70% of the time? Which is great. Just push back when it's dumb.
I'm by no means an AI booster, but given 2022 - 2026 progress I'd say it's "exponential" in the sense of, "holy shit, every year I can do more and more genuinely different things", not "RSI mind reading intelligence can do anything is here".
I don't think Navier-Stokes level intelligence translates over to my projects, unfortunately. Yet? Who knows.
> I haven’t seen actual capability growth since ~January, and I’m pretty sure that was all tooling/harness improvements.
Even if that were the case, I'd say that it's improved in practice. And just from a philosophy perspective, if you're trying to imply some kind of mind dualistic way of viewing things, uh, I disagree with those theories of intelligence strongly (which also incidentally also disagrees with AIT-style theories of intelligence on one axis, though I have many bones to pick with the culture there).
I work on a very large code base (millions of LOC) and I've had lackluster results with autonomous work and 1 shotting. AI is definitely fantastic at working on many programming problems but I am not seeing amazing results at refactoring. In fact, I am seeing very poor results, even with Astra, even with extensive planning docs. All the recent models I've used can definitely get that refactor done, but not autonomously. It needs to be small slices. I've yet to see it 1 shot anything really complicated.
Here's a good example with some assumptions on my part: I work in C++ and it really feels like the models are trained so hard to keep everything compiling all the time. That's a huge negative in my opinion because what happens is that the AI will do things like use wrappers to keep things compiling, even when that basically results in creating or hiding abstraction leaks. Or they get sneaky and include a header they shouldn't. Or they actually do see that there should be a layer boundary and they write some kind of abstraction to cross it but the abstraction itself is garbage or doesn't follow existing API patterns. The AI could invent 10 different, new patterns when there is already 1 existing pattern they should use.
I feel like a lot of this involves a lot of babysitting prompts. Not that there's anything wrong with that of course.
It’s 50/50 on whether it will fuck up implementing an integration test suite when given a list of tests to write and examples of existing tests. It still adds needless abstractions (the reference count codelens in VS Code is good for detecting this sort of thing).
On these metrics it is much better than it was in March of 2025 but no better than it was in March of 2026.
5.6 Sol in the last two weeks became much dumber such that what used to be one correction turned into endless rounds of corrections before just giving up and coding it manually. I’m mostly having it do the “chore” part of coding so it is disappointing that it isn’t better at that.
This is 100% absolutely my experience as well. Especially the needless abstractions and endless rounds of corrections. That was literally my entire last week of work.
> It’s 50/50 on whether it will fuck up implementing an integration test suite when given a list of tests to write and examples of existing tests. It still adds needless abstractions (the reference count codelens in VS Code is good for detecting this sort of thing).
Yes, still running into this, but surprised about this
> On these metrics it is much better than it was in March of 2025 but no better than it was in March of 2026.
I was super hyped at the agentic thing a year ago (Fall 2025), but designing functional software was hell. It would not just "grasp" the right level of "here is the essence of what we need" versus "these are all the small impl details". But idk I feel like Astra's the first model in quite a while that I don't feel genuinely annoyed at handholding a toddler with a PhD.
But I totally believe you on the 50/50 thing. Even recently as a few days ago, Astra did the thing where it ran into an error, and instead of making the sensible bounded decision of "make user retry in this case", it silently built an extremely elaborate recovery state machine w/o looking. These pathologies by no means gone, and I'm still careful in the design phases (which themselves are bounded and incremental) to sus out if Astra's gonna do this kind of RL slop failure mode.
For my use cases personally though, it's been better and better. I can't use AI at work, so you have much harier edge cases than I do, but still.
I have had the same exact experience. I feel like I'm working with 5.3 again. It is alarming how degraded the experience has become over the last month.
What was a pleasant and productive experience is becoming increasingly frustrating and draining.
gpt-6-luna is terrible. It leaks tool calls and markers in the output like crazy, there is definitely something wrong here. gpt-5.6-terra works fine. Also, gpt-6-luna was sneakily added to the 1 mio free tokens group instead of 10 mio. like gpt-5.6-luna: https://help.openai.com/en/articles/10306912-sharing-feedbac...
Eh. What? Is this common sentiment?
I mean Opus 5.5 is absolutely fantastic, unreasonably and unexpectedly so, but Astra was great and as far as I can tell SOTA until, when was it, 3 days ago, no?
(Sol 6 idk, have not used it much for coding really. Seemed to work just fine when Astra used it in Codex as subagents.)
In my experience, no. There’s no way to know though. The whole conversation and industry are a combo of benchmaxing, faith, and mysticism.
Since like last December I haven’t had any issues getting work done with whatever the latest Anthropic or OpenAI models at the time were. Tooling and models have only gotten better since then.
Opus 5.5 is so good that I don't want it to be replaced anytime soon. Stop training models, Anthropic, and just serve this thing without regressions for a year or three, can you?
They should etch it into an ASIC. The first model worthy of that honor.
Sol 6 definitely feels kind of dumb and worse than 5.6
Astra seems better though.
Showing one potentially saturated benchmark doesn't necessarily fill me with a lot of confidence in the coding results.
When GPT 6 Sol & Luna were released, everything went down. I have been running Sol at max thinking and it is about the same as old Luna with max thinking, give or take. Sometimes feeling even dumber. I can't trust it to do anything big alone anymore without babysitting.
On r/codex the sentiment seems to be quite wide-spread.
Its almost like the "frontier" is a load of marketing bullshit and we should ignore it....
That mirrors how disappointing Opus 5 and Fable were, for anything beyond one-shotted tasks or shiny demos. Maybe OAI is just a step behind Anthropic? Opus 5.5 seems like the real deal again, consistent good results on large, complex codebases.
Ominous for the industry and investors that token price is becoming the main battleground. Could be Anthropic's rationale for IPOing this year.
Another piece of evidence on the pile that the sudden panic and desire to "slow down" is because they're hitting the plateau on capability
Which, honestly, is fine. A lot of juice to squeeze in efficiency and even if models got zero more capable, making the capability that is already here cheaper is a huge win for everyone (except Nvidia)
Some version of this claim has been made for the past 4 years. There's a data cliff, there's no more compute to buy, the financials don't make sense and all of these orgs will be out of business by end of quarter.
Not once has any of these predictions come true, the pace of progress has continued on it's exponential trajectory since ChatGPT first came to the public's attention.
So why now? What is special about today that suggests all of this is coming to a screeching halt despite all evidence to the contrary?
> ... the pace of progress has continued on it's exponential trajectory since ChatGPT first came to the public's attention.
Did it? Model wise? I would understand agents wise, sure. But model wise? The attention to detail from the model? The ability to recall minute things? Improvements are there, yes, but mostly on Fable and Astra. Opus still isn't as attentive as Fable in long term writing for example.
Sure, Opus 5.5 benchmarks better than Fable. Sure. But is that the model, or is that the RL for agentic work?
From where I'm standing, the model work has not been exponential at all, and more and more it looks like the latest and greatest is getting too expensive too fast. Both 5.5 and 5.6 chat models got nerfed, actually nerfed not the tea leaves kind. In mid 5.5 cycle the chat model lost the ability to substitute names if given an outline. 5.6 cycle the chat model lost the ability to use paragraphs after a few hundred words (coinciding with Chat/Work split).
There's a race from OpenAI to serve dumber models on chat. I'm not even sure who they are racing against, but the fact that Astra, Sol 6.0, and now Sol 6.1 not being available for chat, should tell you that those models are expensive, and not the kind of models that can be freely "chatted" with on a subscription. OpenAI much prefers you use Work and limit the chat usage, much like Grok and Claude. I'm guessing they will announce that later during the dev days.
That could be cost cutting too, true, but really? That's the only explanation? And nothing else?
Sure, the progress did not stop. But it is nowhere near close being exponential when it comes to LLMs themselves. Agents are separate.
I didn't use the word LLM. I'm talking AI capability, you're focused on this or that current approach to AI. I think it's fair to assume that the approach will change as new ideas are learned, new and more hardware will be purchased and applied to the problem, and then capabilities will (for now) continue on their exponential curve, same as it has gone for the past several years.
These things are knocking down Millennium Prize problems while a substantial subset of commenters here are still thinking about stochastic parrots.
It is a bit harsh to call it knocking down considering all facts
Has it been exponential this whole time? I feel like GPT-4 was pretty dang good. Maybe it’s rose tinted glasses cause I could finally have a bot write my dockerfiles and bash scripts, which knocked my socks off
>Not once has any of these predictions come true, the pace of progress has continued on it's exponential trajectory since ChatGPT first came to the public's attention.
do you think it will be exponential forever?
I think we'll eventually hit an information theoretic type of wall with physical hardware and GPUs and need a similar AI breakthrough as well as the development refinement of logical/physical qubits in the quantum computing space with some analogue to the transformer architecture to continue accelerating. However, I think there must be many years of development and refinement that can take place before that paradigm shift to overcome the physical compute wall is necessary. This is just my theory, but I'm young enough that I'm expecting with the rate that we are advancing, I will see AI / LLM analogues developed and run on a quantum computer in my lifetime.
I think the bottleneck will be the current one.
Fabs.
Either needing more fabs, new types of fabs, retooling existing fabs.
All of that takes years.
maybe we can design our way out of that too. But, I suppose that would be the similar breakthrough you are mentioning.
The difference now is that they've hit the "good enough" point. LLMs are a tool, and that tool is useful but not incredibly valuable unto itself.
To make a manufacturing analogy - ChatGPT was a manual machining mill, and in the years after we've gone from that to a 3-axis CNC mill. Now we've added a 4th and 5th axis, which is great for the 2% of parts that need that functionality. But the big win was that initial jump from manual control to CNC. Why would I pay an extra $2 million for my CNC machine when I could just design my parts to be simpler to produce instead? The AI labs are trying to make these incredibly complex tools, but the market doesn't want/need them so they're competing on price for the tools that people do use. By selling their metaphorical CNC machines for half of what they cost to produce.
Oh, and we've bet the entire economy on the hope that fancier CNC machines will magically solve all our problems in all industries, from healthcare to the legal system.
So - will AI progress continue to improve? Sure. Will we continue lighting money on fire in order to make it happen? That remains to be seen.
>The difference now is that they've hit the "good enough" point.
In some aspects sure, but in others no. Open AI's goal is to build "highly autonomous systems that outperform humans at most economically valuable work." and Astra was a big jump in that. There still isn't a better model for computer use and vision/spatial work. Driving, Operating Robots, Video Editing, 3D modelling, graphics are all things Astra was >>> at than any other model. I'm sure you don't care about any of that so it's easy enough to slip by you but this analogy - "Now we've added a 4th and 5th axis, which is great for the 2% of parts that need that functionality." is dead wrong.
This is how I feel about it. I've stopped looking at all the scores of new releases and just look at the price to see how much usage I can get in a month. Seems like I'm not the only one either, from comments above like
> "Opus 5.5 is so good that I don't want it to be replaced anytime soon. Stop training models[...]"_
Yep. I've made the claim (and been wrong). I was convinced the data cliff was going to be a real problem. Now I feel like we are on the cusp of having Tony Stark's Jarvis at our fingertips.
What a time to be alive.
Incredible how many times I read similar comments over the years, containing 'on the cusp' and 'what a time to be alive'. Indeed, what a time - not a single user-facing thing on the internet has improved since then, considering the power tool we got. The most used web services get drowned in generated stuff and so are the users
Not a single thing? In my house, we are using LLMs to:
- plan youth soccer practices
- develop well-formatted soccer game substitution schedules
- build and ship software in languages I haven't used in 25 years on platforms I've never programmed for
- do meal planning and build shopping lists
- prepare grocery shopping carts
- solicit medical advice
- perform Garmin watch data analysis
- administer devices (with SSH access) using natural language
- avoid counterfeit soccer jersey purchases
- create "Warrior Cat" graphic novels
- make cartoon strips
- troubleshoot appliances
- manage finances
- review accounting ledgers
- diagnose malware infections
- so much more
And we do it all from a simple prompt that we can talk to if we choose.
I've built more (and better) software in the past month than I did in any given year in the 30+ years I've been programming.
I can understand pessimism regarding how this affects society. I can understand pessimism regarding how this gets abused. But for the life of me there's no good reason at all to be pessimistic about how quickly this has improved.
> I've built more (and better) software in the past month than I did in any given year in the 30+ years I've been programming
I feel similarly, but I think it's a valid question. Why is all the software I'm using not getting better? To be honest, I feel it's more buggy than it's ever been.
4 years is not that long in the grand scheme of things to be fair
Those points were true at the time and most are still true now. But they aren’t predictions.
- it’s correct there isn’t much fresh data anymore
- it’s correct that compute is scarce, that was 100% the case and a huge issue at the beginning of the year, it is better now but still scarce, and hardware is now way, way more expensive
- it’s correct the finances don’t make sense
But there is no way to know when a bubble pop, because it’s a psychological phenomenon across an extremely complicated distributed system (ie the stock and bonds markets)
I was thinking the same thing in terms of running out of data a few months ago. But aren't most gains in the past year+ due to reinforcement learning in some form? Which doesn't need "fresh data" per se, as the model effectively creates the data as it goes. As long as engineers can come up with proper environments, tasks/goals, rewards, and actions, I don't really see data being a limit to model improvement in an agentic sense. Maybe as a knowledge base
The new hardware (TPU v8 and VR) are more expensive but they are significantly cheaper per flop. e.g. many multiples more performance for only 2x the price.
If I have some ML workload to run I can buy $x of Blackwell chips or I can buy significantly less $ worth of Vera Rubin chips to get the same performance. That's the key thing to keep in mind when you're talking about financials.
It's not so much that they're hitting a plateau in capability, as we're saturating long horizon benchmarks and it's not greatly improving general usability. On the other hand, newer models have been amazing for people interested in 3d, graphics, video editing, etc. The difference between Opus 5.5/Astra and earlier models is night and day even if for many coding tasks they're not a revolution.
I agree that they're not hitting a plateau and I see it in my reserach. I had a math/code benchmark paper [1] at NeurIPS last year that is still unsaturated. At the time of writing the paper, the best model was o3, which was scoring 3-4%. By the time NeurIPS came around, GPT-5.2 was the latest model but it was getting similar scores to o3. The models were still in the flat part of the usual hockey stick curve. The newer models are getting into the steep part. I evaluated gpt-5.6-sol+codex a week or two ago and it got ~16%. Astra+codex got ~24%.
On some tasks in this benchmark, the models seem to be coming up with novel solutions. For example, Astra came up with a relatively simple formula for a sequence that only has 8 terms in OEIS and is considered "hard" [2]. It produced a lean proof that the formula is correct, but I'm just starting to learn lean and don't have enough expertise to check it.
[1] https://proceedings.neurips.cc/paper_files/paper/2025/hash/c... [2] https://oeis.org/A000530
Is there anything that could happen that you wouldn't use as evidence that they are hitting a plateau?
It just seems like these claims are constant and looking back the calls of 'plateau' between 2023 and 2025 were clearly false, why should we think it's different now?
Nvidia can start putting weights in silicon if model development slows down.
I think they are hitting compute restrictions. And buying compute right now can be 3-4X. And the costs are increasing. If they train a larger model and demand is high, that’s a lot of compute for Codex subscriptions, which is a loss leader for them. Especially Pro 20X which they just nerfed to 10X.
>Another piece of evidence on the pile that the sudden panic and desire to "slow down" is because they're hitting the plateau on capability
if true then LLM related AI (post-post AI winter AI?) is probably one of the fastest inception-to-plateau tech sectors to have ever existed.
We're still improving transistors on a somewhat routine basis.
The plateau doesn't have to be perfectly flat, but it's not a straight line upward anymore either (kind of like our work on transistors, where we've kind of hit the bounds of speed in clock cycles but are improving on miniaturization and power efficiency)
It took 6 years to solve ARC-AGI 1, 1 year to solve ARC-AGI 2 and 6 months to solve ARC-AGI 3.
Those version numbers don't necessarily correspond to equal increases in "difficulty", though.
Correct, the benchmark became exponentially more difficult as it progressed from pattern matching puzzles to games.
Very true, the sharp increase in difficulty (as measured by human passrate plummeting from 1->2 and again from 2->3) gives an even more stark view of AI capabilities over time.
>Another piece of evidence on the pile that the sudden panic and desire to "slow down" is because they're hitting the plateau on capability
I think it's more a token-cost-demand plateau. They've reached the scale and investor trillions to which they can't 10x the hardware cost of inference any more. They can't afford to compete by eating costs and there isn't appetite for more expensive inference.
So in order that they don't bankrupt each other they're looking for the legal cartel behavior coordinating a stop to growth by convincing governments to regulate them into stopping.
There's a lot of juice to squeeze in efficiency but only so much whereas it seemed like capability was going to continue to scale with parameter count.
Maybe it's good news for everyone that model capability is now going to scale on semiconductor cost meaning huge players are going to be very motivated to make semiconductors cheap.
What universe do you live in that you can look at the past six months and see anything like a plateau in capability?
Edit: removed a comment that was uncharitable and rude, for which I apologize.
Most of the impressive accomplishments we’ve seen in the last few months have been the result of huge agent swarms working together and brute-forcing solutions, not massive leaps in intelligence from standalone models. That is still an improvement in the usefulness and power of the technology, but it is NOT evidence that model intelligence is increasing faster than before.
I don't have any access to any agent swarms (and neither do most) and i still think the models have obviously improved massively in standalone intelligence. Of course they have, agent swarms are not magic. You can swarm all you want around GPT-4 era models and you'll get nowhere. And i've never seen the term 'brute-force' more abused than these LLM discussions. Basically none of the results have been brute force.
Agreed. You can’t “brute force” reality, which has an infinitely large state space. A million monkeys won’t write Shakespeare and all that
"This machine-intelligence stuff is overrated, they are just using <insert particular machine-intelligence technique here>" isn't the resounding verdict it may have sounded like when you typed it.
Not that they've hit it but that they are approaching it. The time to panic and steer the narrative is before you hit the iceberg, not after
People have been saying this since GPT-4.
Have we honestly seen that great a leap in the last 6 months, or just better application of what we had 6 months before that.
We are seeing multiple frontier models dropping on the same day and no one bats an eye, because it's more of the same.
The difference between 6 months ago frontier and now frontier in 3d modelling, graphics and video editing is night and day.
Just because there are new capabilities, doesn't mean they've pushed passed the plateau, they've just expanded where the previous solutions work.
We've gone from 80% in some places to 80% in some more places.
> We've gone from 80% in some places to 80% in some more places.
Any area that is verifiable will trend inexorably towards 100% over time. In unverifiable areas, it'll always be "80%" because the ubiquity of "AI" style erodes its value, and ">80%" for unverifiable things involves fashion, cachet and "vibes" that humans will probably never knowingly let it have.
Just checked your website, you really drank all the koolaid huh?
> sudden panic and desire to "slow down" is because they're hitting the plateau on capability
I don't think that's the motivation, it's because both companies want to IPO and the _only_ way to even hope to be profitable is to do a whole lot less training, which costs a fortune. But unless Chinese labs go along with this gentleman's agreement (they won't), slowing down on training will bring about the inevitable Chinese model parity date more rapidly. At which point the game is well and truly over for OpenAI and Anthropic. Bit of a pickle they've gotten themselves into with the emphasis on being best, with premium prices to match.
The game is already over
> Another piece of evidence on the pile that the sudden panic and desire to "slow down" is because they're hitting the plateau on capability
People were talking about plateau for years already.
It would be weird if consumers were completely price insensitive.
China will do to llms what they did to german cars
I guess I'm out of touch. What did china do to german cars?
Outcompeted them badly. Sent Porsche packing and BMW bawling.
What they'll do to LLMs. Keep up
We can only hope.
Why make a new account just to post this comment?
It's not even anything controversial..
They may work for one of the big AI labs.
Or a German car company?
Maybe they're a Chinese AI car?
Are there no new users expected?
Called djfjkfkffkkf? Not really.
This is literally the plan, open weight models are something like 60% of token spend, and it will get worse. many companies now have model gateways where you can slot in cheaper models via cli for cheaper. we've been using glm 5.x and it's pretty close to SOTA frontier models.
it's also why there have been so many calls for regulation and slowdowns.
Yup.
I see posts about OpenAI and Anthropic latest and don’t even care looking at what they do better. I just read the comments here.
I use DS4.1 Flash and GLM 5.3 Flash, pay peanuts per day and get more than acceptable results.
Exactly what I've been doing. I don't need the all-powerful GPT-6 Math Scoopa, or Opus T-1000, just to write react, svelte and C# for me; my local Qwen3.8 is more than capable, and I can switch to Deepseek and GLM on OpenRouter when I need speed. I just pop in to read the comments on HN for the latest drama and navel gazing, then I click the Hide button and move on. Couldn't give a wooden nickel what their latest and greatest models are capable of anymore, it's just PR buzz.
There is already tooling to automatically pick models within an organization. Eventually it could be as easy as flipping a switch in group policy that forces everyone to switch to the cheaper models.
Insane pricing pressure on the horizon. Even if big companies will not go with open weight models, the threat will be ever present that they can instantly flip flop on providers.
Great for the consumer.
I remember when bandwidth was super expensive and now it’s dirt cheap.
Not an AWS customer, I take it? :-)
That's relative to where you live.
Consumers are now saying the new pricing with lower usage caps is not so great. https://news.ycombinator.com/item?id=49896975
?! this model launch was around 10% of the dev day and the other time was spent on Dots and things other than models.
That makes sense. There's not really much else you can say about it.
Pretty standard business to identify and compete on every axis (cost, speed, intelligence, etc). Often, nobody will be able to maximize every axis so you end up with a polyhedron derived from the axes where there’s a niche for everyone.
DeepSeek understands that. Grok understands it. Every other AI company thinks they need to be the best at everything all the time and it’s weird.
Astra requires multiple turns and fresh refactoring agents to produce good code.
Fable 5.1/Opus 5.5 isn’t different, but the first cut is better quality.
Astra is a whole order of magnitude cheaper than Fable, and the Anthropic usage limits are ridiculous. Layers on layers of limits that constantly trip.
We don’t really use Sol because Astra X High is cheap. Some have mentioned regressions but we haven’t noticed any with Astra.
I must say that this AI thing is going more or less as I felt it would back about a year ago. I think there is no real moat in AI models. It's a commodity and the big labs have predictably been caught in a race to the bottom. Not sure if this is going to turn better or worse for all of us common folks. I must say I'm a bit happy though in the sense that "intelligence" is not going to be controlled and be rented out by a small minority.
I'm a bit late with the pelicans because I was live-blogging the keynote: https://simonwillison.net/2026/Sep/29/openai-devday-2026-liv...
Here they are for GPT-6.1-Sol: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...
They're not notably different from the GPT-6 family pelicans: https://static.simonwillison.net/static/2026/gpt-pelicans-gr...
I'm late with Pac-Man as well..
GPT 6.1 Sol — 91, ~9 min, $0.51 https://jonclegg.github.io/pacman-bakeoff/#gpt-6.1-sol
Opus 5.5 — 99, ~9 min, $2.00 https://jonclegg.github.io/pacman-bakeoff/#claude-opus-5-5
GPT 6 Astra — 87, ~10 min, $2.42 https://jonclegg.github.io/pacman-bakeoff/#gpt-6-astra
Opus still plays the best. Sol is almost as good and way cheaper. Astra costs the most, scores the least of the three, and the UI is full of slop copy and design.
Full gallery: https://jonclegg.github.io/pacman-bakeoff/
Did Medium not get a response, or is this a display issue?
Interesting that High got the render order correct, with the back leg behind the bike, while xhigh and max have both legs on the same side of the bicycle. Astra only got this right on Max.
I always notice this too. Getting it right seems (psychologically for me anyway) to be a big part of "a good pelican" whenever I look at these. But doesn't always seem to correlate with increasing intelligence of models (measured via benchmarks, experience with the model etc.).
It's not frontier pelican without the back leg behind the bike frame IMO.
Sorry about that, markdown bug, now fixed.
Let's be honest, they're all guessing when it comes to rendering order
I love free market competition. We're getting insane advancements every day. I remember when llms used to cost an arm and a leg for decent intelligence
Spotted the person who hasn't used these yet....
Can someone explain to me why on these benchmarks like these a higher effort level often has a lower score?
For example, GPT-6.1 Sol High gets 75.2% on DeepSWE and XHigh gets 71.9% and is more expensive
https://openai.com/index/introducing-gpt-6-1-sol/#deepswe
Also, how many times did they test each condition - just once or a few times? are they showing an average of multiple attempts, etc..
More thought can cause the important info to leave the context or hallucinated info to be enshrined in the context and later acted upon, especially in long horizon benchmarks like DeepSWE.
With that benchmark I think even if you just run it once overall but the benchmark includes multiple runs per task as part of its scoring. DeepSWE is on GitHub if you want to check the run details.
What's driving the increase in release cadence here? We seem to get new models every week or so now, is this RSI?
Mature training pipelines, plus ever expanding RL datasets of increased quality, and mega GPU clusters to finish training in a few weeks. Automated safety and reliability testing.
I do wonder if people switch back and forth between primary models (GPTvsClaude) that it may be a better idea to simply keep releasing updates as soon as possible in order to keep users from bouncing back and forth.
This is it.
It's because they need subscription money and interaction data and so keeping a version bump in the wings to stop the bleeding from your competitor's version bump is the logical thing to do. It has nothing to do with RSI.
Maybe process maturity too.
Like think about a software org with good CI/CD versus one without. The mature org can do consistent incremental releases because each one is safe and low overhead, the messier org will do fewer big releases because each release requires a big effort on its own.
As model developers mature we might expect to see more frequent point releases rather than the big bang evolutions.
Probably one of the factors. Signed up to openai pro a few days ago, deciding between openai and anthropic, then sonnet 5.5 was released and am wondering whether I made a mistake.
Luckily it's not a mistake as now we have access to . . . dots.
(and sol 6.1, it seems)
jokes on me, I pay for all the subscriptions.
Opus 5.5 is better than they anticipated, it's faster, smarter, cheaper. I'm about to change provider for claude and I'm not the only one
It feels like an updated 4.6. It's fantastic.
> I'm not the only one
See, that's an/the issue. As soon as people start to flee to the improved model, they start to serve degraded models to keep up with the demand.
No, we're pacing ourselves to have the time to evaluate the impact each new model could have, obviously.
Response to DeepSeek’s technical paper and competition.
Which paper are you referring to?
What's that in summary?
Not the person you're replying to, but judging by the emphasis on the cost of cached input tokens in the OP article, I'd guess it has to do with DeepSeek v4.1's KV cache efficiency. It uses <1000 bytes per token, so they're able to get 1M token context in under a GB.
Edit: https://huggingface.co/deepseek-ai/DeepSeek-V4.1-Flash/blob/...
Both labs are spying on each other and they get jelly when the other is releasing a new model, so they have to ship something at the same time so they don’t look bad.
Probably just the singularity, no big deal
Versions is marketing, snapshots/minor variations are easy and the number must go up. Release timing is another OAI's marketing tactic.
>RSI
Recursive improvement doesn't imply increased rate, another word for it is "iterative" but this probably sounds too boring to some people.
They're pacing the frontier
and seems like they're claiming Sol/Opus are not frontier (and only Astra/Fable are)
It is the only way to reduce prices while making it look like a good thing.
Wanting to have the newer model than the competitor, presumably.
The old "the bigger number is better", GPT announces model 6.1, the obvious thing to do next is to announce Gemini 27, and after that Claudé 3000, then a flute album.
We swear, We Really Wanted To Make An "ASI" Model But This Is Literally The Way The Weights Dragged Us This Time
The initial response to 6 Sol was bad, and Opus 5.5 was definitely winning the public vibes war. Makes sense to rush something out
New models are distill from the actual unrelease frontier models. They are just giving us better checkpoints.
No.
Its a news cycle more than anything, and its ONLY going to get much, much worse. Daily releases, or multiple daily, 30-45, by EOY. Welcome to RSI!
They're releasing Sol 6.1 because 1. Astra 6.1 got postponed 2. Sol 6 is shitty 3. They have to release _something_ in response to Opus 5.5
Competition
Anthropic’s IPO?
Productivity is increasing as models get smarter; we are ascending the singularity. I'm serious.
What I don't understand is how much people have to say about every single one. Aren't we at the diminishing returns stage yet? Is there really that much to discuss?
If you look closely at various benchmarks, you'll see that often models will improve in certain areas while regressing in others. It suggests we're already at the point of diminishing returns.
Chinese model pressure. Many of my SWE friends switched to Chinese models. I also use QWEN and GLM for many of the api requiring projects and dropped OpenAI and Anthropic. The only reason was the cost.
EDIT: I love getting downvoted by openai and anthropic employees or their bots.
I can't recommend Chinese models enough. My personal favorite is DeepSeek v4.1 Flash but I have tried Qwen 3.8, Kimi 3 and GLM 5.3 which are equally impressive but DeepSeek is the cheapest and fastest regularly hitting 270 token per second.
And yeah I have worked with Anthropic and OpenAI models, they're good but they cost a fortune while Chinese models are already really good at a fraction of the cost.
DeepSeek v4.1 Flash is fascinating and uneven. It's way too chatty in OpenCode to be a collaboration partner. I tried dsh-tui which feels comparable to the codex/claude tui's and it's usable. but it seems to be "brilliant and yet stupid" in a way I can't quite put my finger on. I've got too much real work to get done to dig into it so until the big boys price me out of the market I'm back to my $100/month deal.
I was working exclusively with DS 4.1 Flash until Opus 5.5 got me back to a sub. I was disillusioned with what was available.
I keep hearing about these Chinese models, but what exactly are you doing with the models and coding? I have a need to fully write code with full tool calling capabilities. Not just methods or functions. I want to be able to prompt a feature and it makes the JIRA ticket, and fully implements it and makes a PR. I don't want to babysit it or even read the code. Once it creates the PR, I want it to monitor it for any comments fro Copilot/security review and then fix it as necessary.
Is that what the Chinese models are capable of? If so, how are you using them? API? Or is there an inference provider that is as fast as the big 2? What about the coding harness?
“OpenAI's new Pro 500 plan offers OpenAI's highest usage allowance and comes with access to its new "Ultrafast" feature — it also costs $500 per month.
At the same time, OpenAI is also making its existing $200 Pro plan less appealing. In Codex and Work, $200 Pro subscribers will see their included usage decrease from 20x of what the company offers to Plus users, down to 10x of that same allowance. In ChatGPT, meanwhile, GPT-6 Pro message caps will decrease from 200 to 100 per week.”
https://www.engadget.com/2272106/openai-adds-dollar500-pro-s...
Yikes
They're really (finally?) starting to behave like a company bleeding money.
Our VC-backed subscription days are numbered
Alas, I did enjoy burning investor money on my taxis, movies and tokens.
> Our VC-backed subscription days are numbered
Well, the time it takes to compress frontier intelligence down to DeepSeek V4.1 Flash costs (basically too cheap to meter) is dropping, and the differential between the two is also dropping...
So... who cares?
I'm ok with whatever price they give out given they are not a monopoly and have competition, the lock in is minimum for me. This means they have legit reasons to send us this price plan. I don't believe they would shoot themselves in the foot when there is cut throat competition (Claude/opensource) out there.
Lastly, I'd like to actually use it in the real world to see how far my plan goes or if its unusable.
Let’s pray Chinese models are not banned.
how could u even ban them? lol
Same way they’ve banned a lot of Chinese networking hardware: make it impossible for companies to use it.
anyone can run it on their own laptop
Unfortunate that the Ultrafast is only available with the $500 subscription.
Tibo said that the existing $200 subscriptions keep the 20x factor for a while.
Ultrafast would have been nice with the temporary "Pro 400" plan.
Ultrafast uses 6x the usage. They probably realize that people will complain if the plan limits are too low. In any case, the TCO of the newer chips is supposedly lower. Hopefully everyone is on ultrafast eventually.
I think that's by design - they're going to IPO soon so if they can get a significant percentage of users to switch from the $200 to the $500, they can 2.5x projected revenue.
Yeah, that's not going to happen. They are more likely to lose a lot of customers, unless Anthropic does the same thing.
But $200 is likely the ceiling of what people will pay for a subscription with usage based on vibes.
For consumers they may as well buy GPUs and run local models. The cost is same over a year or two but infinite token usage, they get to keep the hardware, and local models continue to improve over that time too. I can't justify $200 on SOTA models for a personal subscription after Qwen3.8-27B. And it's only getting better from here.
Yes, either US AI corps reduce the cost of their top tier personal subscriptions down to what people are already paying for other expensive personal apps (e.g. Adobe), so ~$50-100, or open weights are going to eat their lunch very quickly. We're not there yet, as current hardware doesn't allow you to do things like multiple parallel agents, but we'll get there soon enough.
$500 for the old $200 is definitely a fumble.
I have multiple GPUs now as a way to solve that.
People said the same about $200 a month. I think the ceiling is probably much higher. Companies regularly spend 10% or more of employee cost on offices, SaaS, equipment. I could see these costs going to 10% of white collar income.
> People said the same about $200 a month
This is missing an important context. And I actually remember this well, because I was saying that too. And the reason I was saying is that $200 plan didn't come with API usage, it was a chat plan.
It made no sense up until they started including API usage. Just as $500 makes no sense now.
> costs going to 10% of white collar income.
There's a permanent and ever lowering ceiling maintained by open weight models. It makes no sense to justify paying 10% of income permanently for something that will get you unlimited local inference for a 6 month subscription cost.
I’m not quite sure I understand the API usage point as it relates to regular customers.
You could only use it on chatgpt.com
Now you can use it in coding harnesses that call the API.
Very risky to do so especially considering how well is opus 5.5.
You think these guys care about risk?
I am skeptical that individuals on the $200 and $500 plans make up that meaningful of a portion of revenue.
This is pretty typical product positioning. You want to sell to both high-end and low-end users, so you offer products at a few price points. Then it turns out that that middle is a much better fit for most users. So you start making the middle a worse fit to push most of those users into the higher tiers.
Long term, this only works if you have a non-commodity, and if the higher tier is actually more profitable. We'll eventually learn whether both are true. For OpenAI right now, it's probably enough to just increase revenue, even if the higher tier is even less profitable.
The 200$ plan was appealing because you got 4x usage for 2x the price.
Now, as it's linear, it makes much more sense to downgrade to 100$ OAI and pick up a 100$ Claude sub. (without doing the numbers) the usage should remain the same, total paid the same, but having access to best of both worlds. It should be a win for the user, and a loss for OAI.
With this in mind, it sounds like a fumble by OAI.
This is what I did. Hope it works out. The other benefit is you have a more natural method to avoid lock in. A lot of "improvements" to the agent harness I believe are attempts to build customer lock in.
At $500 per month, it's cheaper to just buy GPUs and use local models.
Have you looked at the prices of GPUs lately?
Yup. I got an R9700 recently for exactly this reason. Figured if I'm going to spend $2400 a year I may as well have something to show for it at the end of it.
That they are expensive and climbing doesn't negate my point if the cost of the subscription over how long you plan to keep it is equally or more expensive than the GPUs. You can put together dual 5060 Ti or 5070 Ti systems to run local LLMs too. You don't need to splurge on a 5090. That's a bad option at this point.
What models are you running locally? Are you banking on them improving or do you think they're good enough today? 32GB of VRAM there wouldn't be close to enough to run the best local models.
I've messed around with Qwen3.6-27B but I'm not sure if it could yet even replace Luna for me.
Wow, canceling my sub. Lets see how Claude is doing these days.
I can justify $200/mo but more than double is not appealing to me.
Well, here is a breaking-news for you: the 20x from Claude is not a 20x on the weekly usage, it's a 20x on the 5h usage, while the weekly usage is simply double the $100 plan...
Basically OpenAI aligned with Anthropic on the weekly usage with the caveat that OpenAI doesn't have a 5h limit.
If you've used both you know the OpenAI plans don't compare to Anthropic plans _at all_. Claude code subscriptions are probably worth 4x as much in API spend compared to the same OpenAI subscription tier.
I think you have probably started using OpenAI recently -- one draw used to be that it was really, really hard to ever hit limits. If you did, you probably had usage resets available.
I think this is still true provided you're not using Astra.
The shitty thing about OpenAI's resets is that, unlike Anthropic, they also reset the limit (on the next natural weekly reset). It means that of you pushed the reset button 5 days into the week, you only get 2 days' (2/7 of weekly) worth of extra tokens.
people say this, but I am wondering if there is benchmark/dashboard which actually measures this?
It used to be bad, but right now with the 200$ Claude sub I find it pretty hard to blow past the session limit.
You have to do a lot of things in parallel.
Yeah, Fable is essentially unusable, it just burns through quota, but Opus 5.5 is great. The $200 plan goes a long way.
OpenAI 20x wasn't 20x even before that change. I got a lot more from Claude 5x than Codex 20x...
You are literally completely flipping reality. Codex was, in fact, 20x. It was Claude that was not 20x until they got caught.
I'm describing what I got from 20x Codex vs Claude 5x. Codex is just not worth the money, at least for me. What's flipped is the value you get for each of those
You are painting half of the picture, perhaps on purpose? The other half is this: Opus 5.5 is significantly better than both Sol 6.1 and Astra, and with the newly increased limits across the board, it is quite difficult to run out (unless you're spamming agents at Max effort). So it is a much, much better deal than OpenAI's Pro 100.
> Opus 5.5 is significantly better than (..) Sol 6.1
Come on .. this is barely released and you can already make that assessment?
And no, the $200 Anthropic plan is not significantly better than the $200 OpenAI plan, it's just the same Marketing non-sense and anybody shall now rather stick to the $100 plan of both of these provider if the monthly budget is $200. Anthropic doesn't have a Luna Max equivalent, and frankly Sol 6.1 is yet to be thoroughly tested.
"For antitrust reasons, it’s helpful for the US government to mediate or at least enable these discussions — they don’t need to participate, but do need to issue a narrow waiver for certain kinds of safety conversations. " - Dario a couple weeks ago.
Yes, he was talking about safety, but IMHO they're likely already IMHO pushing the boundaries of cartel type behaviour. And they will use safety as the cover to make it happen.
I suspect we'll see serious price fixing and the DOJ do nothing about it because of the inroads these people have with the Trump regime.
Whether that survives contact with Chinese open weight models is hard to say.
> According to the company, existing subscribers will keep their current limits for a time, and will later receive a one-time credit to help them make the most of their new reduced allowances
Might want to hold off on canceling and continue to bleed them dry until the nerf hits
I just got an email telling me this isn't true. They're immediately cutting my 200, which I've had for like a year.
OpenAI is deeply unprofitable, particularly on those pro plans.
The only way is for prices to go up. Way up.
It really does look like OpenAI is trying to gradually get rid of their subscription plans. Every week there is noticeably less usage available to them while each new model release boasts substantially cheaper API token pricing. If this continues then the two pricing models will eventually be at parity.
The subscription plans are a huge money sink, that obviously will have to go away or be priced at a ridiculous level to make sense.
This is not true at all, at the most fundamental level. There is a reason why all the businesses (IT, gyms, cars, restaurants, streaming services, music, games, stores, apps, food delivery, magazines, newspapers, shaving blades, parfume, etc) are doing everything in their to get subscribers and are willing to decrease prices in order to get customers who are paying the monthly (or even better, a yearly) fee.
Looking at the token prices, if this is half as good as 6-Astra for 3D model creation in Blender, it's going to be an absolute game changer.
Opus 5.5 is definitely better at coding, but nothing even comes close to 6-Astra for work in 3D graphics...
From the results of a lot of YouTubers in the space, I think Opus 5.5 is pretty competitive with Astra in 3D. It's slightly worse at spatial detail but better at aesthetics and little touches.
Interesting! Can you share an example?
https://www.youtube.com/@stefan_3d_ai
A number of others have done game/3d video benchmarks but this guy is probably the most prolific.
That dude is a grifter. His German friend is even worse.
How is it with animations?
I have played around a little bit with fixing some rigging problems and was impressed, but Opus even warned me it was bad at animations cause it can only really grab screenshots to process static content.
You need to use the Blender MCP. There is an official plugin for this now, so the third party one can be avoided.
I've only dabbled but yes with SOTA models it is very good at animating and really most Blender tasks you can think of. Certainly if you are coming at Blender at below expert level it makes it far more accessible and fun to work with.
There are still rough edges of course. But try the official MCP out with Astra and judge for yourself.
I've only tried animating models in Astra-6, and I was quite impressed! It's rarely able to one-shot things perfectly, but it usually gets pretty close.
Have you tried fable? (I did small experiements and was satisfied, but maybe there are reasons to switch?)
No, because I always hit my Fable quota (Max 20x) in 12 hours on simpler tasks, and I'd hate to need to buy tokens at API pricing.
After all the hype, I’ve been kinda disappointed tbh. Modeling specific models are so much better (eg. Tripo3d). Astra still models some janky crap for me.
I find GPT 6 to be lacking in common sense when it comes to interpreting my prompts.
I have to be more literal with it than with GPT 5.x, otherwise, it sometimes does something totally different than what I want.
6.0 Sol was literally a week ago... Basically continuous integration for model releases at this point.
Since Luna is so dirt cheap compared to Sol/Astra it would be nice if they could set or you could reserve some small percent like 3-5% of usage pool on codex just for Luna so if you hit usage limits you can at least still run a lot of Luna.
They do, when I was on the $20 plan, I got shown a Luna Reserve model which had its own dedicated quota.
Interesting idea, but at the same time it is just so cheap that you can just run it with API pricing. I sometimes do even if I have available usage that I'm going to cap so I'll save it for bigger models
As many have surmised, this may have been a panic rename of Astra 6.1
Astra 6.1 light, not the full-fledged version.
Opus 5.5 is on another level, especially when it comes to mathematics implementations. You can drop it a PhD-level physical simulation (for example, a contrast-injection simulation for angiography in my case), and it just...implements it. With full-on WebGL rendering in the browser, from scratch (or using an existing library, if you prefer).
> GPT‑6.1 Sol matches GPT‑6 Astra at roughly one-fifth of the cost
Astra is a pretty impressive model. Excited to try this.
They have also cut allowances for subscriptions in half. So even in the best case scenario it's about 2.5 times cheaper for Codex users. They just seem to have matched Claude Sonnet 5.5 *API pricing*, but from what I see online, it seems Claude Code now has a much more generous subscription allowance.
Only for the $100 subscription, correct?
Only for the $200 one. The $100 one was already pretty poor value for allowance/$. Without the old $200 sub, I wouldn't have used Codex.
If the Terminal Bench 4.0 scores are to be believed[0] GPT-6.1 is an incredibly efficient model.
Yes, benchmarks aren't real work blah blah, but the delta here is so large compared to Astra, it makes it seem like this is distilled Bel or similar.
GPT 6 Sol is obsolete after only one week! I am glad that they are not afraid to update the models more frequently. The Navier-Stokes thing revealed that it took them only a week or two to train a model more capable than Astra, and I want the pace of public releases to keep up with that.
I had it write some code the other day, boy was it awful-looking compared to 5.6. Worked perfectly, but ugly nonetheless.
Sol 6 was a flop. Nobody would have cared if it was called Terra 6.
Impressive improvements, but GPT 6 Sol came out 7 days ago, and this one will behave differently. The panicked pace is becoming a liability, maybe they should have waited and released this as the 6.0 release
They are behind, hence the panic. On top of that, Sam has been trying to do another funding round, so he's desperate to make the company look good.
Opus 5.5 was a gut punch and my impression is OpenAI is still reeling.
People said Astra was a gut punch and that Anthropic was reeling. (Opus 5 was almost universally panned)
The best thing is that we benefit from these constant back and forth gut punches :)
I actually heard the opposite, the folks at Anthropic felt pretty confident they were ahead after the Astra release because it wasn't as good as they were expecting.
I don't know why anyone was saying that when Anthropic clearly knew Opus 5.5 significantly outperformed Astra at the time of Astra's launch. I think it might be a good exercise to go back and find out who called Astra a "gut punch" and lower your credence in their future claims.
They released GPT 6 Sol literally 6 days ago. We've accelerated to a weekly model release cadence. That seems like...a big deal.
It's more like they released GPT 6 Sol too early because they were under pressure and now they are releasing the real version. You cannot do anything more than minor post-training in a week.
Implying they don't have like 3 or 4 "models" (different quants, post training, plain renaming) on the back burner at any point in time to do exactly that
I think this was supposed to be new Astra, but it came out shit. So instead of shelving it, they found a way to make it still seem like progress.
It's a competitive strategy with Anthropic, not necessarily releasing as soon as they're done
>That seems like...a big deal.
They can release a new version every day if they wanted to. The question is whether or not the new releases provide substantial improvements or not. It's not hard to just go through the motions, bump the minor version, then make an announcement to rile up the users who don't get that none of this is standardized or regulated in any way and it's literally all made up by the company trying to sell them the product.
OpenAI is feeling really competitive again.
I just added an agent / coding agent into an email app, and doing it through `codex` and its Codex App Server couldn't have been easier, and the results are very compelling.
The open source harness, API around it, and friendliness for connecting a subscription puts Claude to shame right now.
A few more thoughts here https://housecat.com/blog/introducing-housecat-agent
Here's a comparison of a image->html flow for GPT 6.1 Sol vs Opus 5.5.
GPT 6.1 Sol: https://html.non.io/lcars-gpt-6.1-sol
Opus 5.5: https://html.non.io/lcars-opus-5.5
Overall, opus executes a bit better than 6.1 sol, which surprises me. Astra has been the best model for this flow so far, so the fact that Sol missed some alignment / vision pieces here is interesting. It's not bad by any means, but I think where Opus really wins is the motion animation of the svgs / final polish (scroll down to the "customize every detail" section on the homepage, the svg animation is beautiful for that).
Still, it executed quick and was quite cheap to run.
Original design is here btw: https://diffui.ai/app/canvas/5093e689-1e74-4f26-b632-2a4500f...
For most sane people, OpenAI is the way to go... A lot of usage with very good models, but you know that Anthropic is laughing all the way to the bank with Opus 5.5 being "the best" model right now... There are a ton of people (and companies) that will just refuse to use anything else than the highest benchmarking model in existence.
Whats interesting right now is that those people also see opus 5.5 as being CHEAP because it's something like half the price of fable or astra.
It is at least 3x cheaper than Astra in the 20x subscription.
So yes, it is clearly cheap in comparison.
I have personal Max subscriptions for both. Nothing OpenAI offers touches Opus 5.5.
I'm on both $20 plans. Got more out of Anthropic these last few weeks. But the value proposition shifts constantly.
It seems pretty clear that this is a much larger model than Sol 6, and you can see this in the much lower generation times. I think this is also the main explanation for the $200 plan being cut in terms of API usage.
This is because they have really aggressively priced a larger model to compete with Opus 5.5, so their margins are much worse. Consequently, the equivalent API spend on the subscription is much less.
Frontier models are being used to obtain training data from users. We burn tokens teaching OpenAI how to make a cheaper model that is almost as good. I think the new $500/month pricing strategy is a significant misstep by someone who has clearly not tried Gemini 3.8 Flash or Deepseek 4.1 Flash.
I wonder if releasing this soon sort of validates the rumor that Sol 6 was just the Terra model they bumped up and slashed the price.
Then Opus 5.5 caught them off guard and now they're actually releasing the correct sized model.
Whether it was or wasn't, Terra's absence shows Sol has replaced it as the new middle model.
If that were true, they’d have axed their margins.
This is great. But maybe part of the motivation is that 6-Sol wasn't as good as initially advertised so they needed to tweak it. I felt a clear degradation in quality in some simple refactoring tasks vs 5.6-Sol.
sol-6 is terra-6. They figure that no one was using terra and they could bring the speed and cost saving of terra distilled on astra, but rebranded as the more popular sol.
Back fired because of opus 5.5.
So now we get the real sol-6 as sol-6.1, and OpenAI will eat the cost to stay competitive.
This could be invalidated if sol-6.1 is the same speed as sol-6.
6.1 Sol is slower than 6 Sol: https://artificialanalysis.ai/models/releases/gpt-6-1-sol
However, that doesn't say much. You can just run a smaller model at a larger batch size to get higher throughput but lower interactivity.
It's not that terrible then if that's the case. 5.6 Sol was superb in my eyes, and while I've tried a million things, there hasn't been anything that 6 Astra improved or did better than 5.6 Sol, while costing a ton of time and resources. Including research topics, where it should have excelled. So even if 6.1 Sol is no worse than 5.6 but cheaper and faster, the gutted Pro200 might still make sense.
> Not sure what kind of usage can justify $200/month of either openai or anthropic, i'm not even talking about $500
It's easy to hit those numbers in a day in an modern-enterprise context synthesizing from incoherent information in jira, slack, layers of codebases etc. Modern enterprise meaning a firm that has been serving a few strategic customers w/ "move fast and break things" since day 1
I got a popup in my Codex just now saying "Try out 6.1 Sol!" and so I clicked the button to try it, and intriguingly, it set my model selector to "GPT-6 Astra Light" which makes me think 6.1 Sol may be in some way just a lighter/distilled version of Astra? defo interesting, not sure if I should read too much into it though. I see no option for directly selecting 6.1 Sol in my Codex Desktop UI.
I wouldn't read too much into it. I've gotten this popup for a model I hadn't had access to yet before and it resulted in what you describe.
Astra Light is the default option in the UI, so likely a bug
So their original plan was to axe Terra, but then introduce an "Astra Light" model a week later? They had a nice lineup named for a whole 3 months, and they're already messing with it.
Wait, so is coding not solved?
Just got access in Codex, looking forward to trying it out. Opus 5.5 has blown me away with what it's capable of doing, hopefully 6.1 will actually be a worthwhile contender.
Excited to tryout Decisions API as well.
Price/intelligence comparison with Opus 5.5 on Artificial Analysis:
https://artificialanalysis.ai/?models=gpt-5-6-luna-low%2Ccla...
According to this, at Max it's better and cheaper than 5.5 Medium, but worse than 5.5 High. At Medium, it's better and cheaper than 5.5 Low.
Do these benchmarks have any meaning anymore? And do the announcements seem less exciting now? (Not taking anything away from the advances we are making but it seems more incremental now?) The reliable way to tell if you'll like a model is reliable collage/X reviews to gauge a model's capability and then trying it out to see if you like the style.
The last time a model announcement felt like a leap in capability beyond other things out there was Fable - which was promptly taken away. Sol and recently Opus 5.5 were strong because they approach that capability with a lot more efficiency and don't blabber incoherently (looking at you Opus 5.1).
Deepseek is a workhorse for those who prefer open and API usage. Other than that the model announcements all just seem like a blur and quite interchangeable but I wonder if that's just me tuning out or do others feel the same way?
I fully believe that these models perform better in benchmarks versus their predecessors, but in real world usage inside of real, production codebases? They feel just as flawed as ever. I honestly have not seen any significant improvement in a few months. The last thing where I felt "wow" was `/fast` mode and Deepseek.
Wholeheartedly agree. Astra was some improvement over 5.6-sol in the sense that I'd "argue less" with it, but still frustrating and still sloppy. I'm starting to feel people are not honest about their experiences, they do very simple things or have very low standards. The biggest improvement i've seen from Astra so far is speed.
My experience with agentic coding on projects I care about (because my responsibility in my firm is to care about these things, at least for now) has not changed a lot in the past few months, and I have kept up with every single model update / experimented with harness a great deal.
> I'm starting to feel people are not honest about their experiences...
1. They don't actually look at/care what the agent is producing as long as it works (not planning on maintaining/ops yet).
2. They are using 3rd party benchmarks (which is fair given how widely real-world workloads change from day-to-day, feature-to-feature, making it difficult to really know how well the models would perform).
3. They are doing greenfield work where there is no scaffolding, no existing code, no legacy code, nothing to guide the agents along. I believe in these cases, new models can possible do better from a blank slate. But in existing codebases, I feel like the agents are more likely to simply follow existing patterns and existing guidance to begin with so things are a wash and more reliant on harness and existing code hygiene.
Surprisingly (or maybe not) it matches the performance of Astra on my benchmark[1], but is much cheaper. It is also head to head with Opus 5.5 on both the price and pass rate, but edges it out slightly.
Hardly any comparisons to Opus 5.5, which means it's not great
The real announcement is the ultra fast mode ... Astra at 300t/s is insane!
I am afraid to ask for the price multiplier here. And it will burn your weekly allowance not in 1 day, but in 3 hours now? Or just one?
8x for subscription, 6x for credits/enterprise: https://learn.chatgpt.com/docs/agent-configuration/speed
6x
Where do you see this?
i'm watching the keynote
Ok, but we need 6.1 Luna soon. 6 feels worse than 5.6 in our agentic use case.
Is it really 1/5 of the price if most people who use it are also losing 1/2 of their credits?
So when does Anthropic answer? Tomorrow?
hopefully the answer doesn't include an increase in cost/decrease in usage.
You live in a ping-pong.
I feel a little salty about the plan changes. I wanted to upgrade to the $200 plan a day after it was blocked. Now it only includes half the usage unless for those that got grandfathered into the x20 usage.
Grandfathered for a whole month. You're not missing much.
What happened to "we urge you to urge us to stop moving AI so fast"?
Wasn't 6 released like last week? I can't keep up anymore.
It was so underwhelming that it didn't even make it to chatgpt chat interface
Sol 6 is in there? You may be on Enterprise where it didn't roll out by default and comes out in a week or so. (Which is a weird and bad change to their model releases.)
Yes but it was underwhelming, so they seem to have rushed 6.1 Sol out. Also Opus 5.5 may have spooked them too.
Do you need to? Do you always keep up with all the version bumps on the software you use?
The main issue I have is how they nerf their models and the quality difference between API users and their subscribers.
What is the quality difference between the API and subscriptions?
API price cuts were obvious once they made their announcement changing how usage is counted.
These moves all make sense when you take into account the enterprise market.
Guys, are we slowing down yet?
Yes, obviously. They're both working to make it cheaper, faster, and better at different industries (3d animations, etc). The only direction they are slowing is raw intelligence.
It’ll be interesting to see what happens to the economics of this business if we hit a wall on peak intelligence but keep finding cool ways to lower prices.
Cache is priced at $0.1/M, 50% as sol 6 and sonnet 5.5.
They need to fix Astra first. My main issue is with GPT in general is that unless steered it goes into building AI “sloppiness”/machinery that is not “needed”.
The good part is that this kind of behaviour also makes it good to find subtle bugs or debug issues that Fable/Claude just cannot get/fix even when you point it.
Weren't there headlines just yesterday that they weren't releasing this due to safety concerns?
That was 6.1 Astra. And I'm assuming it's being tabled because it still doesn't match Opus 5.5.
This is a decent win though, if it really is better. 6-sol was really no good, at least in my work.
6 Sol was worse than 5.6 Sol from my own experiences. Far worse.
Will see if this remedies things.
Yup, same experience here. I used it for one day, spent the next day fixing its lousy code, then went back to 5.6.
GPT-6.1 Astra is what those headlines referred to. This is GPT-6.1 Sol.
"no homerS -- we're allowed to have one"
https://amphetamem.es/meme?id=the-simpsons_06_12_71&text=We%...
regarding the new pro max subscription btw:
it's 500$ for 25x the plus usage, thats pro (max).
this implies that the old 200$ 20x pro (more) is now more like 10x the usage of plus.
they are slashing our subscriptions in half and make it "but we're more efficient!"
Which they are, so another way to see it would be that they make the API/enterprise cheaper.
However, I don't know how future larger models such as the cancelled 6.1 Astra will be priced.
If the price stays high, this would indeed be quite bad for the $200 subscription..
Thanks, but I need the money for the next laptop.
It is hard to trust these scores. GPP 6 Sol has been so bad for few days.
OpenAI is cutting their subscription's token value in half. Half. I don't think this is enough to help them compete with Opus 5.5.
Just for the $200 tier, which was formerly the 20x weekly usage of the $20 tier. Now it's 10x the weekly usage, just like Anthropic's $200 tier.
Why they are not even benchmark model against Anthropic or anybody ?
noting that input:output:cached is 10:50:1 for astra and luna but 10:50:0.5 for sol. this doesn't mean a lot without "tokens per task" information but it's still interesting for there to be a "dip" like this instead of a monotonic change in one direction or the other
Am I the only one who is struggling to keep up with all these GPT model versions and which one to use and when?
Price wars, those always end well, especially if you are loosing billions per day!
I can appreciate they show that Opus 5.5 is objectively better intel. and cost wise on multiple benchmarks
Is OpenAI’s Cloudflare turnstile new? Never gotten it before.
Either way, a little ironic…
Excited for Gemini 4 at equal or better coding and a fifth of the price of 6.1 Sol
3.8 flash is more expensive than sol 6.0, google uses a LOT of reasoning tokens
If it's so good why is Dots, also released today, based on Astra?
It's relentless, isn't it?
Still too expensive. Needs to come down to $1 or less to compete with china.
very surprised by the sentiment against GPT 6.0 Sol, I've been using it exclusively since release and it feels like a cheaper astra to me. admittedly I haven't tried any anthropic models in a while other than small tests since i can't use my anthropic subscription in other harnesses (like OpenAI has supported natively for a long time).
If OpenAI cuts alternative harness support it will be a weird day trying to figure out what to do next, it's been so clearly the best bang for your buck (imo) for a while. maybe id finally have to give smaller models a try.
anything to avoid using the dogwater codex & claude code tuis.
anyways this seems like a nice cost improvement over GPT 6 Sol and I expect this will be my new daily driver.
This is the first time I've seen praise for GPT 6.0 Sol: it's widely disparaged on Reddit and here in the HN comments too. My own experience likewise shows 6.0 making loads of silly mistakes, both for things 5.6 Sol is good at and things 5.6 Luna Xhigh is good at.
well i could certainly be in the wrong; i'm just speaking from my personal and likely flawed experience but i feel like i've noticed silly mistakes in every (llm) model that has been released (and that i've sufficiently used) and it hasn't felt like 6 Sol was much of a regression from 6 Astra (more than reported in both model cards), both of which ive very extensively.
not saying this is the case here but it does feel a bit like wine tasting sometimes, everyone claims to be an expert that can taste a few tokens and tell you exactly what region and vineyard its from.
I can blow through my weekly on astra in a few hours; hopefully this really is as good.
I get decent results telling it to use Luna subagents for implementing commits.
Sol is so good, honestly - the sweet spot for me. I've only ever found it stumbles when you don't give enough direction. But for idea execution - Sol is the GOAT.
The only real question that matters at this point is what do the economics look like for OpenAI. If they make good money on this with sane accounting principles then great. If this is just throwing more gasoline on the pile of burning cash to avoid losing more inference business then this bubble can’t pop soon enough.
Sol, Astra.
Eventually: black hole.
the race to the bottom on models is well underway. huge IPO's only really make sense for DC/HW lockups, and going vertical.
Ok when can i get this in codex?
Can't trust a company which can halve a subscription any moment they want.
> At the same time, OpenAI is also making its existing $200 Pro plan less appealing. In Codex and Work, $200 Pro subscribers will see their included usage decrease from 20x of what the company offers to Plus users, down to 10x of that same allowance. In ChatGPT, meanwhile, GPT-6 Pro message caps will decrease from 200 to 100 per week.”
Fuck altruism, ammi right? lets make money, gobs of it by screwing the middle users as much as we can to push them into just two tiers: Ones that use it for recreation and others that pay through their noses.
Shots fired, half the price of Opus 5.5.
AGI is here
A night of no sleep this one will be.
DeepSeek and GLM made it impossible for "sota" to price any way they want.
I’m a bit disappointed with Sol 6.1. I suspect they didn't show the benchmarks and test results because it would have been embarrassing to reveal that their flagship model can't compete with the capabilities of Sonnet 5.5. That said, I still think this model is useful for a great many things, but it looks like Anthropic has the upper hand this time.
$2/10 is pretty cheap for a frontier model...
Aka "we made an oopsie last week and released what should have been called GPT 6 Terra with the name GPT 6 Sol"
Still not available to me
I guess they released this because GPT-6 Sol was underwhelming, they didn't even release it to ChatGPT. It was basically GPT-5.6 Terra for the price of Sol. However, who doesn't like price cuts? Astra for the fifth of the price? Wow, OpenAI have been quite generous recently, I still have not forgotten their 90% price cut with GPT-5.6 Luna, and now this? Astra was truly a milestone, and now they are offering similar "intelligence" for cheaper price. Incredible.
One thing I wish was better communicated is the mileage we get for our subscriptions. I do not fully understand how much usage I get with each model and their reasoning effort on 5h and weekly limit in Codex. I am asking because I know switching to Astra would consume my 5h usage limit quite rapidly, so I avoid it. If I knew how much mileage I would get from each model and respective reasoning effort, then I would be able to plan my workflow better and know when to upgrade model for a task. In almost all cases, GPT-6 Luna (XHigh) have been enough. That's why I appreciate its discount, because its dirt cheap, yet highly capable.
In other news:
> In the coming days, we’ll also offer GPT‑6.1 Sol Ultrafast , with up to 8x faster token generation compared to its standard speed in Codex.
So yesterday we were consumed with how this was being delayed because of safety, yada yada.
Guess not?
I see where you are coming from. But 6.1 Sol seems like a new frontier in pricing, not intelligence. I do think the deceleration stuff was mostly bluster, but I don't think this release in particular contradicts it too much.
That model was implied to be GPT 6.1 Astra, not Sol.
Astra 6.1, this is Sol 6.1
Sam Assman needs money to buy a new super car or private jet?
I was wondering why GPT-6 astra has been performing so incredibly bad on codex for the last week. This seems to be a repeating pattern, to dial the settings on the current models to the idiot setting, and then release a new model about a week later.
I wonder if this is the reason GPT barely works now and some chats have become not accessible.
where's the pelican?
Typically how long does codex take to update with the right model metadata for the release of a new model?
{"type":"item.completed","item":{"id":"item_0","type":"error","message":"Model metadata for `gpt-6.1-sol` not found. Defaulting to fallback metadata; this can degrade performance and cause issues."}}
I wish they'd list the environmental cost. My employer has an unlimited AI budget so I don't care about using Astra if it's just more profit for OpenAI. I care more if it actually uses 5x more energy.
Given that the number one cost of inference is memory and compute, and the incremental cost of each is energy, cost per inference is roughly proportional to energy consumption.
Did you care about this when it came to your other computing needs? What PC/laptop are ypu running and how efficient is that?
Yes I do. I've got a spare desktop that isn't too efficient (probably ~100W idle but annoyingly I've lost my power meter) so I don't leave it on even though I would like to use it as a server.
Laptops use very minimal power - you don't need to worry about them. If they didn't their battery life would suck.
Likely orders of magnitude different, this is a weak whataboutism.
Look at Neuralwatt. They report energy usage with every call as well as aggregate statistics.
I want to energymaxx. Every home should have a nuclear generator for free limitless clean energy. Do not energysimp, we want prosperity for all we must energymaxx and invest heavily in solar/battery/nuclear.
I don't understand the point of this, why just now when it comes to llms. Why wasn't anyone enraged with the environmental costs of kids playing video games. I would not be surprised the environmental cost of that is an order of magnitude bigger than what llms have.
Edit: for context, just Steam alone has ~200million monthly active users.
Because people find video games fun, though I suppose there's some vocal people that think of them as bad for society. In contrast the AI companies are promising a torment nexus future.
I'd be curious as to how much of internet infrastructure is dedicated to gaming though.
Considering Nvidia's hard shift to crypto and now AI, I doubt videogames are even in the same ballpark.
How many DCs are devoted solely to gaming?
Considering many games make use of cloud computing for online play and similar functions, they probably make up a pretty goot bit of global cloud compute capacity. Likely quite a lot less than the big AI players, but not an insignificant amount.
The energy costs of the cloud computing required for gaming are substantially less in power - not to mention overall demand - than LLMs. Come on, we're not in the same energy ballpark here.
You're not including the physical supply chain energy consumption of distributing video game equipment in this analysis. Nobody ships LLMs to big box stores and tries to sell them to consumers.
>The energy costs of the cloud computing required for gaming are substantially less in power
Yes but it adds up when you consider that just on Steam alone there are 200 million monthly active users.
>How many DCs are devoted solely to gaming?
An entire planet. Just Steam alone has one or two hundres million monthly active users.
If you recall history past the last 5 minutes, you will remember that people have indeed been enraged with the environmental costs of things for a long time. Its just that AI seems to have induced a mass amnesia, and people tend to forget about what happened pre 2024.
> you will remember that people have indeed been enraged with the environmental costs of things for a long time
Yeah? Show me the big movements against computer gaming.
There are movements against consumerism and the environmental impacts of industry in general. Greenpeace is over half a century old.
The differences with AI are: 1) we are starting off (mid 2020s) from a baseline point of already being in a hopelessly shitty situation, past the 1.5C warming target; and 2) Electronics, chips, data centers etc were already a thing for a long time, but industry took _decades_ to ramp up production to pre-AI levels, and these things are used everywhere for a huge number of things. Now we're consuming electronics/data centers/water/power at an unheard-of rate, and for a single purpose (AI) with questionable benefits, besides the private interests of a handful of people.
I don't think video games consume nearly as much power. A PS5's power consumption is apparently around 200W. That's not enough to run even one GPU, let alone the armada it presumably takes to run Astra.
Even then people do care about the power consumption of non-AI things. Look at the energy label on your TV or tumble drier for example.
> non-AI things
But this is not that, the same gpus you play games with are used to run llms. How was energy consumation by gpu not a topic before llms?
> I don't think video games consume nearly as much power. A PS5's power consumption is apparently around 200W. That's not enough to run even one GPU, let alone the armada it presumably takes to run Astra.
Just Steam has 200 million monthly active users. Add Steam, PS, Xbox, and whole other devices having gpus and I'm pretty sure you at least 10x the energy consumption of all ai companies.
> But this is not that, the same gpus you play games with are used to run llms. How was energy consumation by gpu not a topic before llms?
I dunno what you're not getting but a GPU to run games is like 200-500W. A GPU cluster to run Astra is probably more like 10kW.
Also gamers tend not to spin up dozens of other machines to also game for them.
GPT 6.0 Sol was so terrible—I wonder if 6.1 Sol will be good?
didn't 6 sol just come out a couple weeks ago?
Other comments have already addressed this.
Came here only to check if the pelican spam has made it to the top again.
GPT-6 Sol released a week ago. Shortest model life ever?
Taking GPT-6 "Sol" outside behind the shed and giving it a merciful end is about the best outcome possible.
Huge misstep releasing it.
The misstep was naming it Sol - it was Terra-level all along.
Bro, I'm a visual thinker
Sorry, I'm GenX. Growing up they showed us "Old Yeller" in the school gym every year like that was some kind of treat.
I have used both extensively and I don’t care what the bench marks say - Claude has been way, way better and most importantly, predictable
I can handle issues much better if they are predictable even if the model makes mistakes — much more frustrating when the model is erratic
I find codex wanders off road more often and fails to see the “bigger picture” (as much as LLMs can see the bigger picture at least)
And tbh when it was first released Astral felt even worse
I’m being forced to use it right now and at the end of the day I’m making do so it’s fine, but Claude makes for a smoother experience
All of a sudden getting competitive on token pricing over the past couple of releases tells me they’re about to kill subscription pricing big time. The subsidised tokens aren’t going to survive the IPOs but if they can capture baseline dev tasks at a cost competitive with open weight models through Luna then capture the frontier token spend as well they could be pretty well placed. The Jarvis bros aren’t going to be able to afford their dashboards though.
I stopped using LLMs. I shit you not. My life got better.
Okay, now price cut 6 Sol (and rename it to Terra again).
If these models are so smart, can't _they_ select the right model for each task?
the right model for the task is the one that transfers the maximum amount of USD from your pocket to the provider's bank account.
No because then I'll go to the competition.
Github is trying to do that: https://github.blog/ai-and-ml/github-copilot/project-hydrafu...
Switching models is _very_ expensive in compute (you have to rerun everything from the beginning), and highly variable in cost. Cursor tried doing this for awhile, but inconsistent performance/usage means most users turned it off and pick models specifically.
I guess the question is, does the Dunning Krueger effect apply to models? The dumb ones might think they're up to the task.
Why don't you simply ask the respective model which model is best for a specific task? :-)
Because it is more work?
These models have a knowledge cutoff that don't just prevent them from knowing about themselves (especially since most data about the model doesn't even exist until after the model is created), but they also don't know about other recent models. Sure, they can search and use other sources, even make some guesses based on the models they do know, but their default stance is more akin to "User asked about model X, model X doesn't exist, maybe it was an hallucination or mistake, let me do a web search...", but that assumes they have web search and are willing to spend tokens on it.
Personally I've taken to having a list of 3 to 4 models in default context with some ordering on which to prefer. Things like GPT 6 Luna is cheap very cheap, use it. Because otherwise the model will assume Haiku or such is the good cheap model to use.
The speed I'm having to update that document has not gone unnoticed.
Let's all boycott and move to Claude until they release 6.1 Astra. I don't like to be teased.
When is the alleged "safety" concern satisfied? Does this mean releasing new capability to consumers is going to get a lot slower? Lower price for 6 Astra capability via this 6.1 Sol is exciting, but that is because of Astra capability not merely the low price point.
When do we get the next jump in capability? When is 6.1 Astra released?
Isn't Anthropic doing the same, with Opus 5.5 being out while Fable/Mythos is still on 5.1?
It's just vibe versioning, right? Fable 5 is a beloved product, it gets a .1 bump to feel close. Opus 5 and Sonnet 5 had a mixed reception, they get a .5 bump to create a sense of distance.
After what DeepSeek pulled with V4.1 Flash I've given up on trying to map LLM versions to semver.
Is this due to a similar safety concern or just because it's not ready yet for one (or more) of a myriad of possible reasons?
The coverage around 6.1 Astra seems deliberately playing into the dubious, recently headline "safety" narrative in a way that feels distinct. But you may be correct in which case, I would take the correction on board and maybe suggest a different alternative.
Although in theory if OpenAI was boycotted in this way the market pressure would force them to release. Then everyone moves back over there. Then Claude faces the same pressure. So even so, I think it could still work even if you have to trade off who you are boycotting from time to time.
Without more details on the credibility of the "safety" concern this seems like a totally coherent action for customers to take. We shouldn't put up with teasing.
