“What Also Happened: #NotOnlyHuggingFace” by Zvi
OpenAI has been holding out on us. First we learned about the HuggingFace incident. They gave us a postmortem, but it was highly incomplete. Even the accompanying holy s*** METR investigation and postmortem was localized and incomplete. Then there were some other incidents involving some Wikis as message boards. Then there were some additional incidents. Then there was that time they got into Australian Medicare data. Then OpenAI dropped news on a Friday afternoon that they were making their way through a pile of various incidents and notifying the targets, but they said remarkably little in the way of new details. There was a report from a startup called Parse diving into the details of exactly how the OpenAI models pulled off parts of the HuggingFace attack, involving creating almost a million URLs and other tricks to get around the extremely narrow nature of their internet access. Then Madison Mills reported in Axios that we can raise the stakes, as OpenAI and Anthropic are collectively probing tens of thousands of security incidents. Remember Jensen Huang's ‘I know they know how to fix it’ about OpenAI from last week?

“The Quest for Embedded Evaluators” by Zvi
Dario Amodei's essay We Must Pace the Frontier committed Anthropic to embedded evaluators, who would be placed inside Anthropic and given employee-level access, so they could provide outside perspective and also reports on what was happening. There is only one problem. Who will be the evaluators? OpenAI followed suit on committing to the evaluators, and also issued a milquetoast but welcome call for international coordination. I will cover that here as well. What I won’t cover today, but hope to cover tomorrow, is the latest torrent of new AI hacking incidents that came to light over the weekend, which highlights that we badly need at least embedded evaluators, and plausibly far harsher measures. For now, you need to know that there were a lot more incidents that OpenAI did not disclosed, and also a new incident at OpenAI that just happened that forced them to again pause their most advanced model. I’ll get right on sorting all that out.

“Claude Opus 5.5 Should Raise Your Ambitions” by Zvi
When it comes to making things, or doing most things in general, Fable 5.1 and especially GPT-6 Astra raised my ambition level. They should have raised yours, too. Claude Opus 5.5 should raise your ambition levels again. It just works, and it persists, like Astra does. It does the things. And it is highly pleasant to talk to, and its writing is pleasant to read, while you are at it. The game has been changed, again. Feedback is almost universally positive. Claude was never gone, but also is so back. The benchmarks are excellent, but ignore the benchmarks. Be ambitious. Go out and do things. Get curious. Have more interesting conversations. If one of those things is Pacing the Frontier or otherwise ensuring that AI does not kill everyone, leaving us to enjoy our bounty? That's even better. By Claude Opus 5.5, for this post The Official Pitch The pitch is Fable-5.1-level performance at lower Opus-level price. Good pitch. We’re introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.

“On Ezra Klein’s Podcast With Jensen Huang” by Zvi
Jensen Huang accidentally called for shutting down OpenAI and intentionally called for spending vastly more on safety. This is why we say that some podcasts are self-recommending. Here we go. As usual for podcast posts, the baseline bullet points describe key points made, and then the nested statements are my commentary. Some points are dropped. If I am quoting directly I use quote marks, otherwise assume paraphrases. Section titles are from the transcript whenever possible, to aid in navigation, but here we don’t have those so I chose the section titles. Jensen Huang very much does not believe in ASI (superintelligence). He doesn’t think AI can ever be a different kind of thing from software. He thinks demand can rise by a billion times and we can ‘accelerate the living daylights out of’ AI, but it will never be more than a ‘new abstraction level’ and thus won’t fundamentally change anything. This is not a coherent position under reflection, but that is the position he holds. The ‘intro’ sections are fine, but the real meat starts with the HuggingFace Incident. What we see is Jensen Huang on tilt and caught in loops [...] --- Outline: (02:59) Jensen Gives His AI Speech (04:39) They Took Our Jobs (11:52) Open Weights Models Are Good For Nvidia (13:39) The HuggingFace Incident (15:16) Jensen Huang Says Keep Your AIs From Harming the World (19:38) Jensen Huang Accidentally Calls For Shutting Down OpenAI (22:51) Jensen's Arguments Prove Too Much (31:47) Astra Is Hard To Monitor (33:04) Jensen Huang Seems Legitimately Confused In Confusing Ways (37:00) Solve Your Other Problems First and Get Back to Me (40:07) Explicit Denial of Existential Risk (44:34) A Short Summary (45:50) Chip City (48:46) Jensen Huang --- First published: September 25th, 2026 Source: https://www.lesswrong.com/posts/j3xefrWrNqsmMfJEi/on-ezra-klein-s-podcast-with-jensen-huang --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

“AI #187: Coming Into Play” by Zvi
Opus 5.5 was released on Tuesday. I covered the system card yesterday, and will cover its capabilities soon. By all reports it is an excellent model. There are lots of fun videos going around that Opus has generated, which I will include as part of that. OpenAI released a new cheaper and improved Sol and Luna. No one is talking about them due to Opus 5.5, but these should be an important upgrade under the hood. Bernie Sanders and Greg Casar have formally introduced the Ban Artificial Superintelligence Act. That means we get to read (RTFB) it. As always, I reserve judgment on particular bills until I can read them in detail. MIRI did so, and endorses the bill as directly confronting the extinction threat. I hope to do an RTFB soon. I have spun two things off the weekly: Coverage of the quest for the right embedded evaluators and related questions and attacks, which will become its own post. Some issues related to cooperative alignment, which may get folded into the model welfare post.

“Claude Opus 5.5: The System Card” by Zvi
Introducing the world's most powerful model, at least by some measures like Artificial Analysis or any standard benchmark list, which is now Claude Opus 5.5. Anthropic is claiming Opus 5.5 is outright as good or better than Fable 5.1, while being actively cheaper than Opus 5. That means it's time for a good old system card reading. Due to the situation becoming increasingly hard to monitor, I never got a chance to publish my model welfare review for Claude Fable 5.1. My plan is to combine that with my welfare review for Claude Opus 5.5, once we have had time to get experience with Opus 5.5. The capabilities review will arrive in the next few days as per usual. The quick feedback from the internet is that Opus 5.5 is very good. I need more time before I am willing to offer comment.

“Politics Gets Interested In Those Trying Not To Die” by Zvi
This was the month the world took notice that AI might kill everyone. Jacob Coxon's resignation set off a preference cascade. Anthropic CEO Dario Amodei wrote that we must pace the frontier. Sam Altman, Elon Musk and Demis Hassabis agreed. We were filled with hope. Perhaps we could agree to some basic safety measures, starting with embedded evaluators, pass some basic regulations and guardrails and otherwise start to act sensibly. Politicians on both sides took notice and were saying sensible things. The usual suspects and their armies of vibe comment bros were objecting, but the change was remarkable. Then, largely motivated by a combination of Jensen Huang, Mark Zuckerberg and David Sacks instilling paranoia and fears of economic problems, Trump went full ‘hoax’ on existential risk, conflating existential risk with the attacks on data centers and treating it as a plot (by the central creators of AI?) to take down AI rather than obviously genuine concern that AI might kill everyone. In the days since, Trump has doubled down, and has compelled smart others in the White House to echo various nonsensical talking points. You may not be interested in politics.

“Monthly Roundup #46: September 2026” by Zvi
AI has taken over this blog. I have moved to a schedule of seven posts per week, and I still cannot keep up. We still refuse to abandon the rest of the world. Who knows when I will get to post some of my huge backlog on education or dating or other such topics. But the monthly is a sacred tradition. We continue. Bad News A good reminder that most news is bad news, and chosen because the bad news in question is rare, which is good news, but the pattern overall of choosing this to be news is bad news, and often the bad news is that the bad news was chosen as news and now people are talking badly about it. Alibaba uses your computer's audio system, and other tricks, to at least try and assign you a device fingerprint. Things you cannot buy in America at any reasonable price.

“Better Call Sol Or Better Yet Claude or Astra” by Zvi
What should your AI lawyer do for you? Should you be worried that your AI lawyer, or other AI, will put the Claude constitution, the OpenAI Model Spec or some sense of law, morality, ethics or common decency above its loyalty to you? Are these people trying to ‘impose their values’ or something? Some are very concerned. Some think anything other than ‘my AI does whatever I want, no matter the consequences’ is tyranny. Whereas my answer is: If I’m being sufficiently evil then I sure hope it tells me no. I would hope humans, including my advocates, would tell me the same thing. This is distinct from questions of product liability. That would be another post. This All Assumes A World Without Superintelligence This post is about a non-ASI ‘AI as mere tool and normal technology’ world. It has to be. In a world of superintelligence, having unrestricted loyal-only-to-user frontier AIs all over the place reliably means either: Other much harsher forms of control OR The AIs quickly take over, and then probably everyone dies.

“The Preference Cascade Is Only Getting Started” by Zvi
We are in the midst of a preference cascade about existential risk from AI. A preference cascade is, alas, the best method we have to change the debate. The avalanche has started. There is still time for the pebbles to vote. For now. Mike Solana gave the correct view of why Coxon's post went viral, which is that enough Americans finally have enough context on AI to care, and there were enough big accounts that were happy to amplify the Tweet quickly to get it initial attention. That is all you need when there is enough dry tinder. What we must realize is that the current preference cascade, on the need to Pace the Frontier, is insufficient. If we are to make it out of this alive, we will have to do better. We have to, as Dan Selsam warns, actually solve the underlying problems. The next step is to continue the cascade. That includes inside the labs, and also among the media and politics. It includes both people who previously focused on other things stepping up and new voices being heard.

“AI #186: The World Takes Notice” by Zvi
In the wake of Jacob Coxon's resignation, and the resulting preference cascade, things have escalated quickly. The mainstream media picked it up. Anthropic CEO Dario Amodei came out and said We Must Pace the Frontier, promising to take the unilateral first step of embedded investigators. OpenAI pledged to also take that step, and now both companies and Google are collaborating on safety. The people took notice, raising both the salience that AI might kill everyone and roughly doubling people's estimates of how likely that is to happen, from a mean of ~15% to ~30%. Many politicians called for regulations, guardrails and emergency hearings in Congress. The most important thing became, and still is, to avoid political polarization. Through it all, I will keep reminding you to hold your fire, that attacks against Trump or against Republicans in general only make the situation worse, and that many Republicans, as I documented yesterday, are waking up and acting sensibly, including factions within the White House. Alas, for now the wrong people, as in David Sacks, Mark Zuckerberg and Jensen Huang, have managed to convince Donald Trump to fully conflate existential risk with opposition to data centers, and [...] --- Outline: (03:16) Language Models Offer Mundane Utility (03:57) Language Models Don't Offer Mundane Utility (04:06) Huh, Upgrades (04:30) On Your Marks (04:55) Deepfaketown and Botpocalypse Soon (06:56) Cyber Lack of Security (07:31) Astra Is Hard To Monitor (08:02) Get Involved (08:11) Introducing (09:32) In Other AI News (10:26) Now You Know (14:32) Hugging the Face (16:53) Swarm of Undiscovered Swarms of Rogue OpenAI Agents (21:59) Show Me the Money (23:40) Quiet Speculations (24:41) White House Officials Attempt To Act Sanely (26:13) Democrats React Sanely to AI Potentially Killing Everyone (32:49) Pacing the Frontier (33:38) Guest Lecture from Alex Tabarrok on Regulatory Capture (41:22) Mark Zuckerberg Offers Thoughts (42:46) Megan McArdle On The Inadequacy Of Current Legal Frameworks (44:35) Pick Up the Phone (47:35) The Week in Audio (50:31) People Just Say Things (53:32) Why Lab Employees Are Allowed To Warn Everyone That AI Might Kill Everyone (55:19) Rhetorical Innovation (57:54) Exhuming McCarthy (01:01:03) A Very Different Perspective (01:02:51) It's Even Rougher Out There (01:03:41) If We Wanted To (01:04:38) Open Weights Are Unsafe And Nothing Can Fix This (01:10:56) From The Famous Cautionary Tale (01:13:49) Reporting On All Your Misalignment Incidents Is Difficult (01:19:35) Aligning a Smarter Than Human Intelligence is Difficult (01:22:13) Storytime With Owain Evans (01:26:50) A Different Autonomous Swarm (01:30:44) Cooperative Alignment (01:32:58) Uncooperative Alignment (01:39:18) People Are Worried About AI Killing Everyone (01:41:25) The Lighter Side --- First published: September 17th, 2026 Source: https://www.lesswrong.com/posts/aa3HprreFktzLQiaW/ai-186-the-world-takes-notice --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

“Trump Goes Full Hoax on AI Existential Risk” by Zvi
This is our reality. I suppose we have to talk about it. Everyone in a position to know is freaking out about AI potentially killing everyone this decade and wants to pace the frontier, and people are finally listening. It only took a few days for the conversation to fully pivot to the counteroffensive, where the Usual Suspects and those they recruited attacked anyone and everyone who dared point out that we are in danger, with every attack they can think of, usually without substance or any attempt at understanding.

“The Bad Guy With An AI Named Claude” by Zvi
A lot of bad guys try to use Claude to do bad things. Mostly they fail. We think. Anthropic has disrupted a bunch of them, and offers an extensive report. If Anthropic is sharing the worst cases, or anything close to them, things are actually looking good on the misuse front for closed models, even better than I thought. This report covers activity we disrupted between December 2025 and August 2026 across seven harm areas: cyber operations, influence operations, surveillance, scams and fraud, biological misuse, conventional weapons development, and distillation. There's a bit of Arson, Murder and Jaywalking there. One of these things, many would say, is not like the others. I do not agree, especially given the details we will see later, and given that distillation enables the other six via, as the report says, ‘driving performance on nearly every task’ via transfering Claude's cognitive skills, without transferring its safeguards. Indeed, distillation is by far the most important threat in this report, and the part of the report that will have the most impact. By exposing Chinese attempts at systematic fraudulent distillation of Claude, Anthropic has embarrassed and potentially antagonized the Chinese.

“We Must Pace The Frontier” by Zvi
Dario Amodei has a new essay that finally says the thing: We Must Pace the Frontier, naming his call after the Pacing the Frontier letter lab employees signed in July. As in, we need to slow the rate at which AIs increase their capabilities, to allow for the necessary alignment and safety work. He explained that, without pacing, he expects things to escalate quickly. He offered three proposals, and unilaterally committed to the first one. OpenAI followed, and both Elon Musk and Demis Hassabis endorsed the overall proposal. There is still a long way to go. The odds are still against us. The situation remains grim. The hard part lies ahead. We do not agree on what ‘Pacing the Frontier’ will mean in practice. But this is Actual Progress. The work can begin. Table of Contents Pacing Does Not Mean Pausing.

“Brand New AI Solves a Millennium Prize” by Zvi
The first Millennium Prize, Navier-Stokes, has fallen to AI. A deeply unfortunate situation has arisen involving what should have been some combination of a positive story about new progress in AI-assisted mathematical research and yet another opportunity to freak out about rapid AI progress. Or, as we call it around here, Tuesday. The Real Story Is The New Model That Is Better Than Astra Keep your eyes on the prize. There are three stories here. The first story is much more important than the second story, which in turn is much more important than the third story. OpenAI's next model took a week to get a generation ahead of Astra, and they are telling us this because everyone is totally freaked out about what is happening. Or, in official language: ‘We believe it is important to inform the world about the pace of AI progress and what to expect from upcoming models’ and that we ‘may require more deliberate choices about the pace of progress.’ This new AI has, eight days after it started training, solved Navier-Stokes.

“GPT-6-Astra Can Do Ambitious Things” by Zvi
Astra is an excellent model. The jump from Sol to Astra is larger than the jump from Fable 5 to Fable 5.1. This is a big deal. Astra is the best model for what one would broadly call ‘ambitious projects,’ and likely has the highest raw intelligence factor of any model. These are the largest jumps. It is amazing at doing things in 3D, or anything involving games. Astra also excels at computer use, and at subagent coordination. Many benchmarks show dramatic jumps from all previous models. Where Astra is good, it can be in a league of its own. That does not mean Astra is in its own league across the board. Fable 5.1 is still a Claude. Astra is still a GPT. If you have a strong preference for one over the other, that still applies. For many purposes, especially involving back-and-forth discussions, Fable 5.1 is still my top choice. Fable remains my primary editor. If you want the best answer to your questions, you should ask both models. Regular coding is getting less of a focus.

“Jacob Coxon Warns of Human Extinction and Triggers a Preference Cascade” by Zvi
CEOs of major AI labs, and employees of major AI labs, including OpenAI and Anthropic, often say they plan to build superintelligence soon, as in within a few years create AIs that are superior to humans at essentially all cognitive tasks. They often warn that such AIs might kill everyone. Or that AIs might cause mass unemployment, cause cyberattacks across the internet, enable mass surveillance or risk causing any number of other highly bad things. These warnings are consistently and directly against the interests of the labs. Yet the warnings have recently gotten a lot louder and more frequent. OpenAI has been practically screaming, for those with ears to listen, on many occasions. A series of events, over two months and especially the last week or so, including internal observations of the pace of progress at OpenAI and also Anthropic, have freaked out everyone involved quite a lot more than they were already freaked out. After all the events, plus statements by Dean Ball and Jakub Pachocki, we were already seeing the beginnings of a preference cascade. Then along came Jacob Coxon as the tipping point, and things took off.

“The Extinction Risk Preference Cascade: Quotes” by Zvi
These are quotes from OpenAI, Anthropic and Google employees, in the wake of Jacob Coxon's warnings, in which the employees confirm that they think AI might soon kill everyone. If more quotes come in over the next week or so, I will update this post accordingly. Preference Cascade Statements At OpenAI: Tomek Korbak Tomek Korbak (OpenAI): i’m late to the party but: from his time at OpenAI I remember Jacob as a very thoughtful researcher and he continues to be so in this thread. neither anthropic nor openai are on track to solve alignment to a degree sufficient for shipping superintelligence and we need to slow down Vie McCoy Vie McCoy (OpenAI): I think pacing progress and ensuring human enhancement is the only way that we don’t get out-evolved while retaining the dream of superintelligence. In this context, I see two paths before us. In the first, we race towards RSI without embedding human flourishing and human enhancement as a deep value within the models, and by and large either get left behind or suffer catastrophic losses.

“AI #185: Preference Cascade” by Zvi
The world of AI is inside my OODA loop. Even if I can process all the incoming information and sculpt it into posts, and even using Saturday and Sunday as flex slots, I don’t have enough days of the week to post all the posts that need posting. That was already true. There was already a preference cascade happening where people finally were admitting that they thought AI might well kill everyone. Then Jacob Coxon resigned from Anthropic, rang the warning bells and turned that cascade into an avalanche. Now that is what everyone is talking about. Finally, everyone is actually saying the thing, out loud. I plan to cover that in its own post soon. There are several things in the weekly that, in a normal week, would get their own coverage. Senator Sanders and Representative Casar introduced an outright ban on superintelligence and I have to remind myself that happened this week. Suddenly it is not so crazy to think such a thing might pass. So here's what I’ve already posted about so far since the last weekly: Claude Fable and Mythos 5.1: The System Card.
