    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...

    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.

    > 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.

    • TuxSH 1 hour ago
      Exactly half as expensive as Opus 5.5 in every API pricing metric
      • bigwheels 58 minutes ago
        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).

          That's far too vague. I found Opus to be terrific at coding, but human text just seems so robotic with it. OpenAI models used to be the prototype for robotic text, but lately I've been finding them much more natural. What is "something difficult" in your workflow?
          • peterbell_nyc 24 minutes ago
            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.

            This was the biggest thing I noticed in the 6 models; their conversational prose is dramatically less grating.

        • sobiolite 18 minutes ago
          Are you comparing Opus 5.5 with GPT-6 Sol or GPT-6.1 Sol? Because they are different models.

          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.

        • beering 16 minutes ago
          This news and thread is about 6.1 Sol, not 6 Sol. You haven’t even had time to do a fair comparison yet.

          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.

          • krzyk 11 minutes ago
            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

        • Infinity315 56 minutes ago
          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.
          • phoghed 23 minutes ago
            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.

          • toasty228 54 minutes ago
            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

            • copperx 47 minutes ago
              The usage allowances are now insane, like they were when the Max plans were introduced. The $100 plan is usable again for real tasks.
          • colinhb 42 minutes ago
            Yeah totally agree, people keep jumping in w/ strong views hours after release, eg: https://news.ycombinator.com/item?id=49045430
          • beering 17 minutes ago
            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.
          • rspeele 33 minutes ago
            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.

              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
            • squidbeak 43 minutes ago
              If 5-10 minutes is enough, you need a more ambitious one-shot goal.
        • jauntywundrkind 46 minutes ago
          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.)

      • dom96 30 minutes ago
        Based on my benchmark[1] it is the same price as Opus 5.5 and just as capable.

      > 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).

      • redox99 5 minutes ago
        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 obviously true.

        With the 80% price cut, this is competitive with Opus 5.5 despite the subscription downgrade.

        Additionally, it was said that existing 20x subscriptions retain the higher limits for some time.

        I have seen you make these immature accusations that users here are OpenAI employees multiple times today.

        • sscaryterry 23 minutes ago
          It is not obviously true. Please provide real proof. OpenAI's customers are tired of their BS.
      • JimDabell 32 minutes ago
        > most people, get hardly a days usage out of a 20x account

        This is not even remotely true.

        • peterbell_nyc 27 minutes ago
          This is the distribution of usage. Spin up a bunch of loops or fire a semi-autonomous factory at a project and it's pretty easy to blow through a 20x account in a few hours if you can afford the sandboxes, CI and other infra required.

          If you're running 2-3 parallel agent session with a few sub agents and waiting for you to prompt them, you'll have a very different experience!

        if an openai employee is reading this plz hire me i am unemployed and i need a job

        (Usage limits are entirely dependent on what you're doing with them. If you're not running it on 1 million LoC codebases you can get a lot of mileage out of even a 5x account particularly with the recent cheap models)

  • the_duke 59 minutes ago
    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)

    • wkcheng 6 minutes ago
      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.

    • nxc18 54 minutes ago
      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.
      • sigbottle 0 minutes ago
        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 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).

      • user43928 6 minutes ago
        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.

    • btbuildem 17 minutes ago
      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.
    • jstummbillig 49 minutes ago
      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.)

      • phoghed 16 minutes ago
        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.

      • Eridrus 25 minutes ago
        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.

      • copperx 38 minutes ago
        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?

        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.

    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.
    • xyzzy123 4 minutes ago
      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.

      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)

      • luma 24 minutes ago
        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?

        • dgellow 15 minutes ago
          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)

          • moosehater 0 minutes ago
            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
      • sebzim4500 30 minutes ago
        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?

      • CuriouslyC 51 minutes ago
        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.
      • LPisGood 58 minutes ago
        Nvidia can start putting weights in silicon if model development slows down.
      • theturtletalks 57 minutes ago
        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.

        • mixdup 55 minutes ago
          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)

        >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.

      • semiquaver 1 hour ago
        What universe do you live in that you can look at the past six months and see anything like a plateau in capability?

        • arctic-true 46 minutes ago
          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.
          • famouswaffles 38 minutes ago
            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.
            • semiquaver 29 minutes ago

            The whole "pace the frontier" thing originated from Anthropic.

            With Opus 5.5, it doesn't seem like model improvement is plateauing. And Fable 5.5 will likely be dropped this or next week.

            You can only imagine what they've got going internally.

              Just because there are new capabilities, doesn't mean they've pushed passed the plateau, they've just expanded where the previous solutions work.

        > 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.

      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.

      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.

    “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.”

        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.

    • user43928 2 minutes ago
      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.

      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.
      • glub 21 minutes ago
        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.

        • latentsea 13 minutes ago
          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.
          • glub 3 minutes ago
            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.

      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.

      • 5555watch 26 minutes ago
        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.

        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.

        • MCArth 21 minutes ago
          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.

          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.

            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.

        It really does look like OpenAI is trying to gradually get rid of their subscription plans.

If this continues then the two pricing models will eventually be at parity.

        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.

      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.

    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?

    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.

    • unsupp0rted 15 minutes ago
      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.
      • ChaseRensberger 3 minutes ago
        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.

  • glimshe 1 hour ago
    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.

    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.

  • Alifatisk 52 minutes ago
    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.

      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.

        • lp92 57 minutes ago
          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.
          • HelloMcFly 53 minutes ago
            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.

      • IshKebab 18 minutes ago
        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.

            There are movements against consumerism and the environmental impacts of industry in general. Greenpeace is over half a century old.

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.

      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?

        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.

      • godwinson__4-8 52 minutes ago
        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.
