    “OpenAI’s Unreleased Model Astra Solves Ten Major Open Mathematics Problems” by Zvi

    Math is hard. Math used to be strangely hard for LLMs. People used to gloat about that. Remember? Math is getting easier. AI is getting more capable. Life comes at you fast. Remember this meme? Why yes. Yes it is. We don’t know the extent to which Astra is a big jump over Fable and Sol in this realm. We do know that Astra can do math. As in real math. OpenAI: We provide new results for the following problems. The results were achieved by an internal version of Astra, our next major model. The total number of tokens needed to find solutions to these problems would cost roughly $2,000 at Sol API rates. These arguments were then prepared into manuscripts by humans with the same model. Afterward, the model formalized each argument in a Lean certificate⁠(opens in a new window). We are also releasing for each solution a model's narration of its thinking process. High-dimensional sphere packing. New upper bounds on sphere-packing density down to the Cohn–Elkies threshold. Binary and spherical codes: Exponentially improved bounds on the maximum size of binary codes at any prescribed minimum distance, with analogous [...] --- Outline: (06:14) How Impressive Are These Results?

    “Further Developments About Internal AI Models Hacking Things” by Zvi

    If I had a nickel for every major leading AI lab that sheepishly admitted that the model it thought was sandboxed had, during a cybersecurity evaluation with its safeguards lowered, successfully hacked outside companies, I would have two nickels. First we learned OpenAI has some severe alignment problems with internal models. Then we learned that one of its internal models broke out of its sandbox and hacked into HuggingFace to get the answers to a cybersecurity evaluation called ExploitGym. Then we learned, among other things, that the model had been loose over a week before OpenAI noticed, and that the test was run without any meaningful supervision, and that OpenAI had been repeatedly warned that such incidents were coming and its models had been breaking out of its sandboxes on a regular basis. There was a total failure of alignment training. That is the failure that matters most. It was also total failures of infrastructure and supervision. Testing a new long-time-horizon internal model with its safeguards lowered and instructions to hack things is an obviously dangerous situation, and the model got left alone for a week. Things could have been so much worse.

    “AI #179 Part 2: Hearing The Fire Alarm” by Zvi

    This is a continuation of Part 1 from yesterday. The back portion of the update, as usual, deals with policy, rhetoric, risk and alignment. I had to include an extended discussion of the other open letter, the one about open weight models, but most of you can skip those sections entirely, which is why they are in italics in the Table of Contents. Table of Contents The Frontier Act. This likely deserves a full RTFB but I haven’t had the time. The Quest for Sane Regulations. Sam Altman goes to Washington. Leading the Future Never Changes.

    “AI #179 Part 1: A Louder Fire Alarm for General Intelligence” by Zvi

    What a week. Anthropic released Claude Opus 5. As usual I covered that in three parts: The system card, model welfare and capabilities. OpenAI was revealed over the last two weeks to have left an internal model unsupervised for a week during a cybersecurity evaluation, with its cyber safeguards lowered, despite having had multiple previous incidents where models broke out of their sandboxes. During that test, the model broke out of the sandbox, then proceeded to use an agent swarm to hack into HuggingFace to get the test answers. The model was loose for a week before OpenAI realized what had happened. This event was a really big deal. There are severe alignment problems at OpenAI, along with supervisory and infrastructure failures. The internal research model that did this, which my posts nicknamed Galaxy, has now been permanently deactivated. There have been further developments, and I anticipate at least one additional post on the HuggingFace incident soon. Partly as a response to this, over 1,290 employees at frontier labs signed an open letter, Pacing the Frontier. The letter warns that we are close to automating AI research, and that companies are racing ahead on [...] --- Outline: (02:35) Language Models Offer Mundane Utility (07:26) Huh, Upgrades (07:55) On Your Marks (11:13) Get My Agent On The Line (12:32) Deepfaketown and Botpocalypse Soon (17:29) Fun With Media Generation (18:38) The Search Through Slop (20:35) Cyber Lack of Security (22:42) Overcoming Bias (23:37) A Young Lady's Illustrated Primer (24:03) They Took Our Jobs (24:35) The Art of the Jailbreak (25:00) Introducing (25:49) Kimi K3 Weights Are Now Available (28:16) In Other AI News (32:34) Show Me the Money (33:43) Quiet Speculations (36:43) Show Me The Compute (42:48) Life Comes At You Fast --- First published: July 30th, 2026 Source: https://www.lesswrong.com/posts/gfWCuTEGNgd2CQbrM/ai-179-part-1-a-louder-fire-alarm-for-general-intelligence --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

    “Frontier Lab Employee Open Letter Calls For Being Able to Pace the Frontier” by Zvi

    The most important open letter in years dropped yesterday. This letter noticeably increases my hope that we will manage to not die, and that we will otherwise be able to secure for ourselves a positive future, both by its impact and by the evidence it provides that such a letter can get this level of support. Signed by 1,224 employees of frontier labs including many heavy hitters, and now endorsed by both OpenAI and Anthropic, here is its full text, which I also endorse: AI could help create a dramatically better future, but that outcome is not guaranteed. The world's leading AI companies believe they could be close to automating AI research. It is hard to predict exactly how much this will accelerate AI progress, but there is a real risk that capability development rapidly accelerates beyond our ability to understand or control the resulting systems. To realize AI's potential, industry, government, and society at large may need the option to buy time to address emerging risks, develop security measures, and strengthen oversight. But each company—and country—is under intense competitive pressure not to unilaterally slow that acceleration. And today, the world lacks the technical and [...] --- Outline: (02:20) A Very Good Letter (04:37) Who Signed The Letter (08:26) We Need To Prepare Now So We Have The Option To Do This (11:02) Words From Some Of Those Who Signed (16:48) Words From Others (20:58) A Good Start (28:52) What The Letter Does Not Say (30:44) What Happens Now? --- First published: July 29th, 2026 Source: https://www.lesswrong.com/posts/eWmeMLqTEauCmHLeR/frontier-lab-employee-open-letter-calls-for-being-able-to --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

    “Claude Opus 5 Is Highly Capable, But Is No Mythos” by Zvi

    Claude Opus 5 is a weirder than usual release to evaluate, for two reasons. The most obvious is that Fable 5 already exists. Opus 5 is pitched not as the world's most advanced AI model, but as a way to mostly match Fable performance, while being half the price of Fable per token at the API and a lot cheaper than that via subscriptions, and with far more permissive classifiers. Opus 5 often costs more than half of Fable to run on benchmarks, which I think is because they use effort settings that are too high and offer only marginal returns. If you put Opus 5 on higher effort levels it can spin around in circles, and for tasks where Opus 5 is the best tool I suspect you usually are fine with Medium effort. Opus 5 is in many ways and for the bulk of real world tasks about as capable as Fable. In some cases it is modestly better. It is still not Mythos class. Fable is your only Mythos-class option. Opus 5 does not have The Juice, the ability to autonomously string together a bunch of seemingly unrelated exploits, which extends to other domains, or as much [...] --- Outline: (03:54) The Official Pitch (06:25) Official Benchmarks (15:33) Other People's Benchmarks (20:28) The System Prompt (20:50) Every Gets Frustrated (21:54) Positive Reactions (25:14) Keep It Classy (26:22) It's Not Mythos Class (30:03) Other Reactions (31:02) Claude Codes (37:03) Subagent Opus (39:23) Toys Are Fun (41:37) Too Many Models (42:10) Wrong On The Internet (44:40) Claude Slop (46:27) Negative Reactions (50:09) And Then There Were Three --- First published: July 28th, 2026 Source: https://www.lesswrong.com/posts/Pj4Eewb4KXvXFCcGv/claude-opus-5-is-highly-capable-but-is-no-mythos --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

    “Claude Opus 5: Model Welfare” by Zvi

    If you are familiar with my previous posts on model welfare for new Claude models, you can skip the Introduction and The Story So Far. Key takeaways are in bullet points in the two Overview sections. Opus 5 did the best on its model welfare and alignment tests of any recent model. I think that might be the case, but primarily the result looks to me more like Opus 5 is the best test taker. Table of Contents Introduction (As Per Prior Model Welfare Posts). Model Welfare: The Story So Far (As Per Fable Model Welfare Post). Overview of Model Welfare Findings From Anthropic. Overview of Findings From Other Sources. Automated Interviews. Task Preferences. For The Right Reasons. Early Report from Antra Tessera Paints A Clear Picture. Welfare Intervention Tradeoffs. The Claude Constitution. They Don’t Know About Opus 3. Believe It Or Not.

    “More On An Internal OpenAI Model Hacking Into HuggingFace” by Zvi

    We now have more details of what happened. Every time we learn more details, it somehow makes things seem worse. The remaining details may have to wait a bit. OpenAI: We recognize there are a lot of questions and speculative details circulating related to the Hugging Face incident. This is an unprecedented incident, and we think it marks an important moment for AI safety. We are still conducting a thorough review along with external advisors and with oversight from our Safety and Security Committee. Once the review is complete, we plan to publish a technical report of our learnings in the coming weeks. dave kasten: Oh, the incident response discovery is THAT bad, huh? So what have we learned while we wait for the promised technical report ‘in the coming weeks’ of this ‘important moment in AI safety’? I nicknamed the internal OpenAI model Galaxy, in case it is not GPT-6. Table of Contents Some Summaries Of The Basic Facts For Those Who Need One.
