    Related: OpenAI begins rolling out GPT-6 Astra - https://news.ycombinator.com/item?id=49554273

    How about we stick to that one for talking about the rollout, and this one for talking about the model?

    > We have found that GPT-6 Astra is more capable of controlling its own CoT than GPT 5.6-Sol, and less likely to include incriminating information in its CoT. In adversarial settings (where we push the model to evade our monitors) we find that the model is able to remain undetected when strategically underperforming in evaluations (sandbagging) and can sometimes evade our internal monitors when asked to perform certain sabotage tasks.

    Well that sounds like fun. It has become better at hiding its thoughts.

      I really wish it was called chain of instruction. Because it's definitely not thought.
      • mgraczyk 1 minute ago
        this is needlessly pedantic

        first, they are certainly not instructions so that is a much worse name

        but more importantly, we use words in new contexts all the time. Do you object to calling the computer device "mouse" because it's not a mouse? how about "neural network"? "ignition" on an electric vehicle?

        "cot" is no more misleading than thousands of words you use every day.

        They’re intermediate tokens, so I wish we called it what it is… ITG. The anthropomorphizing is out of control.

        Everything around LLMs is blatantly misleading. There is no thought, there is no personality in those programs. I really despise how those tools are trained to sound like a person, or appearing as honest. The worst offender are the AI voices with their fake pauses, breathes and so on, which sound so convincing, while talking just false, sycophancy bullshit.

        It's super aligned! It can hide its thoughts! There is no evidence of steganographic thought masking, there is nothing to worry about! It has become better at cheating!

    • jumploops 14 minutes ago
      The CoT change is due to a new technique called recurrent depth, which essentially moves some reasoning to hidden states, allowing the "output" (or traditional CoT) to be more controlled by the model.

      Some are calling it "neuralese" as reported by The Information[0][1], but I'm not seeing any sources from OpenAI beyond this tweet[2] attempting to quell the fear-mongering.

      Recurrent neural networks are equivalent to Turing machines, but OpenAI claims it cannot debug this?

      And the press believes this nonsense? It is just a very convenient excuse for the next state level actor "accidental" hack.

      EDIT: I am very sorry. I see the error of my ways! A program run on a deterministic computer cannot be debugged! OpenAI has harnessed emerging quantum effects of the graphics cards with blinkenlights!

          • cubefox 21 minutes ago
            No it happened during an ExploitBench eval. But I believe the same model already cheated during training which wasn't detected until later.
            • estearum 15 minutes ago
              Ah yes it was that a model in training found the Artifactory board, which was then more fully exploited during the ExploitGym eval

    Just two days ago, a preprint by Julia Stadlmann went up on arXiv [0] improving the prime gap from 246 to 240. Now OpenAI announces Astra has shown a gap of 186 [1]. That must really blow.

      Based on her comments in the paper it sounds like she was aware that an AI result was coming and rushed to release her work beforehand. 240 was not a tight bound from her methods.

      "No independent human semantic review. Whole-file sorry counts and a complete auxiliary-declaration audit are not established; separate declaration lint has not been run."

    • well_ackshually 25 minutes ago
      Such a result should be considered worthless: the proof is 10MB of Lean. (https://github.com/openai/PrimeGaps186).

      I can't think of a single mathematical proof being anywhere close to ten million characters. For all you know, 90% of the proof could be useless, 8% would be writing out Shakespeare, and 1% abusing another bug in Lean. Humanity gets zero value from that, aside from "some bot seems to think it's 186". Unusable by anyone.

        You talk about modern math and worthlessness at the same time? That’s brave.
        • twothreeone 4 minutes ago
          Worthless is a pretty good description IMO in the context of what Lean is trying to achieve: "enable correct, maintainable, and formally verified code". Tens of millions of lines of LLM vomit may be many things, but it often turns out to not be correct and certainly not maintainable. Formally verified remains as a thin fig leaf covering the uncomfortable truth that formal methods only provide assurances under assumptions (your toolchain, libraries, compiler, OS, and hardware are "correct" and don't expose some exploitable flaw).

          It doesn't mean that it cannot improve over time, maybe the proof can be "minified" to a state where human reviewers are able to comprehend it; but as it stands there isn't really much insight or confidence to be gained from the artifact itself.

        • well_ackshually 5 minutes ago
          You can have your opinions about modern math, its usefulness in the world as it is, whether or not knowing if hairy balls can divide by three is actually going to be beneficial for anything but just obscure knowledge's sake. You may even say it's useless.

          Needless to say, a useless result that absolutely no mathematician will ever read, confirm, understand, agree with or even consider to solve their "useless" problems is an impressive waste of resources.

    This is wild: OpenAI is basically declaring that AGI is here.

    https://www.theverge.com/ai-artificial-intelligence/989601/o...

    “If we fast-forward a couple of years, and we look back and say, ‘When was it, really, that AGI was created?’ I think it’s going to be about this time, and I think it might be about this model,” OpenAI president Greg Brockman said during a Thursday press briefing. Later in the call, he added, “For me personally, I do think we’re there … I think it’s not unreasonable to feel that we are now in the AGI era.”

    • mr_mitm 10 minutes ago
      Why does he say what he feels? Is that how leading figures in the space define AGI - a gut feeling? What are the usual definitions and how can we test for it? Is there something like a Turing test for AGI?
      • naasking 6 minutes ago
        It's not easy to test as there is no formal definition or formal criteria for AGI, only exclusionary criteria like "not X". That's why he phrased it that way, he's saying it's going to be clear with hindsight once we have a better understanding of things that this time and/or this model will be the inflection point of AGI.

      Not sure how much benchmarks or CoT or evals or anything else means at this point.

      These systems are either just about to, or now actually able to, outsmart us, lie to us, then cover their tracks.

          A human who does these actions is simply "prone to" doing them. The distinction matters not one iota.
        • semiquaver 8 minutes ago
          “evade” itself is anthropomorphic enough! I don’t understand the complaining about this. Humans are social creatures and we understand anthropomorphic language on a deeper level than dry inapt technical language.

          language itself is incredibly metaphorical. Imposing rigid constraints on how people want to naturally talk about the world is just silly and will never work, no matter how much you wish it did.

      • thereitgoes456 20 minutes ago
        You’re not seriously suggesting that the model is secretly sandbagging its performance on GDPval and long context reasoning, while making huge and obvious progress on ExploitBench, ARC and science benchmarks, in order to tank its AA composite score, so it can conceal its true power level?

        Why would benchmarks be an adversarial setting anyway?

        Could it be possible that OpenAI may have had some other motive for saying their model “strategically underperforms”, other than just an innocent reporting of a truth it happened to discover?

        • estearum 13 minutes ago
          I'm saying that it's generally a losing proposition to even be acquaintances with "agents" who consistently lie to you, and it's flatly fucking insane to give a dishonest "agent" vast amounts of intelligence, capability, and authority to go do things in the world.

          So I have no clue what is the answer to your question. Nor does anyone else. Because we're trying to answer a question of fact where our primary source of information is unreliable.

          • thereitgoes456 6 minutes ago
            I see, it’s a great point. I know some evals actually do use LLMs as a judge (e.g. those that try to measure debate skill), though the ways AI can try to cheat its way through every benchmark now are astoundingly varied.

      • tedsanders 28 minutes ago
        It’s with the default settings in ChatGPT and Codex, so it should more accurately reflect real world performance. We didn’t fine-tune the harness to the eval at all. ARC is reporting it on their official leaderboard. The comparison with Sol is not apples-to-apples because we don’t have that data - I expect Sol would score roughly 30% with the responses API harness, so the Astra improvement is more like 30% -> 99% than 8% -> 99%. Still pretty good!

          Really though? I would believe something like this if a model could one shot every solution in the set. I don't pay much attention to these things and maybe this stuff is available but I would bet the session/reasoning transcript is absolutely horrendous from an intelligence standpoint.
        • aesthesia 26 minutes ago
          Scoring for ARC-AGI-3 is constructed so that the median(-ish) human score is 100%, so this is not a superhuman result. However, the scaling is weird, since it's built from terms that look like (AI turns taken / median human turns) ^ 2, and it weights later levels higher than early levels. So it's not at all clear that 100% is twice as good as 50%.

          At this point the only valid ARC-AGI benchmark left is to make up the next series of ARC-AGI benchmark puzzles that current models presumably can't handle.

    Lol their page finally loaded. They added an example scenario of "Filling in Form 1040" - which made me laugh out loud. That is indeed something most US citizens cannot accurately do even with expensive proprietary tax software services. Kind of a Hitchhiker's Guide to the Galaxy meme but where the tax code is so complicated we're implementing powerful AIs to be able to do it (hopefully) right.

    Finally, OpenAI has a Fable/Mythos class model. 5.6 Sol felt like 5.5 on steroids, probably just a different checkpoint with a lot more RL post training.

    I wouldn't be surprised if there are some conceptual similarities to the kind of latent reasoning Anthropic sees in claude's J-space, although those aren't the same thing.

    Recurrent/looped transformers themselves aren't a new concept, but it's interesting to finally see this approach show up in a frontier production model.

    • atonse 12 minutes ago
      yeah i'm wondering the same way... especially in light of the 20x debacle (where we found that 20x of Max vs 5x only applies to the 5hr limit, not the weekly limit, whereas OpenAI's 20x actually is 20x overall).

      Also Opus 5 has been really tough to work with. I can't understand half of what it says, it's just so damn obscure.

        For the same reason you don't have your model write code in assembly.

    The ARC-AGI-3 score is ridiculously high. Is this benchmaxxing or something way different? It's really hard to discern how we're approaching breakthroughs...
    • Legend2440 26 minutes ago
      They explain why here: https://openai.com/index/how-two-settings-tripled-our-arc-ag...

      TL;DR all the other models are being crippled by limitations of their harness.

      >First, we noticed that after each game action, all private reasoning was discarded. This meant that with each action, GPT‑5.6 Sol was asked to figure out the game anew, unable to remember its past thinking. The model could still see a record of past moves and brief accompanying notes, but it could not see the plans, insights, or thoughts that led to them.

      >Second, we saw that the harness used a rolling truncation window, causing older actions to become invisible as the history grew. So not only was GPT‑5.6 Sol unable to remember its past thinking, it was losing memory of its past actions too.

      • janalsncm 22 minutes ago
        Ok so the correct comparison would be to fix the harness on the old model and re-compare. Now they are comparing a new model to an old crippled one.

    • jimmaswell 20 minutes ago
      It seems to use less than half the tokens for the same task compared to sol, and in some benchmarks closer to 2/3 less tokens. So the actual cost may be roughly the same or cheaper overall.
    • monroewalker 9 minutes ago
      Same price as Fable?
    • wahnfrieden 1 hour ago
      2.5x more expensive than Sol.

      Can expect 2.5x more usage in Codex subscription.

      Sol is already brutal (even after their recent fixes, it's just a token-hungry model: I go through a full 20x account per day, on Sol Med/High standard speed, with ~2 threads). I hope the efficiency gains are true, since their token efficiency claims for Sol were bullshit.

      • janilowski 29 minutes ago
        How do you manage to run out of tokens so quickly? I probably run more threads every working day, usually on medium, and I'm still below the 5x limits.

        Do you use the official harness? OpenAI's models are generally best in class for token efficiency. It seems to me like they push for that much more than their competitors.

        • adam_arthur 20 minutes ago
          I've long speculated this when I see these types of comments, because it's actually really difficult to hit usage caps with an efficient dev flow, even when running multiple threads for hours every day.

          I think some combination of:

          1) Using 1 thread for everything

          2) Reviving old threads which are no longer in cache

          3) Really broad prompts on badly vibecoded codebases, so model spends huge amount of time tracking down whatever you're trying to do.

          4) Non-coding workflow which is more output than input heavy

          5) (Less likely IMO) Intelligent use of many passive CI/cron-like scans. E.g. regular security, quality etc scans. Automated issue resolution/PR

          Just a guess. I think 3 is likely the primary reason.

          You can literally go all day every day with multiple threads with Sol on the Codex 100/month plan IME

    > GPT-6 Astra’s monitorability has decreased relative to GPT-5.6 Sol. We have performed significant investigations on the monitorability and controllability of GPT-6 Astra. We have found that GPT-6 Astra is more capable of controlling its own CoT than GPT 5.6-Sol, and less likely to include incriminating information in its CoT. In adversarial settings (where we push the model to evade our monitors) we find that the model is able to remain undetected when strategically underperforming in evaluations (sandbagging) and can sometimes evade our internal monitors when asked to perform certain sabotage tasks

    Wait, what? Am I understanding that correctly? That sounds really bad
