Claude Opus 5.5 Should Raise Your Ambitions

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. It performs at the level of Claude Fable 5.1 on most work and costs 40% less to run than Opus 5. They could have reasonably pitched this as above-Fable-5.1-level performance. Better pitch, but Anthropic tends to keep its pitches conservative. They highlight agentic coding, security and improved communications. The early tester blurbs flag as AI generated and they have a set for each feature area. They praise agentic coding skills, efficiency, readability and communication, and ability to effectively run on its own for extended periods and increased reliability, pitching it as a major upgrade. Benchmarks look fantastic, with occasional spots where Astra or Fable is still ahead. Opus 5.5 is available with zero data retention (ZDR). Given it is at least as capable as Fable 5.1,…

On Ezra Klein’s Podcast With Jensen Huang

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, because either he is doing a bit at a very high level, or on a fundamental level he cannot understand that AI is not like other pieces of software. To him this is a product, like any other product. You make it useful, which happened six months ago, then you flip to spending most of your R&D budget on safety, verifications and evals, and of course you would never ship an unsafe product or one you hadn’t properly tested, that’s crazy talk, and if the labs can’t test their products safely then the labs must be shut down. And of course you would never let a ‘race’ or similar incentives get to you, because it is the responsibility of the company and CEO to not…

AI #187: Coming Into Play

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. I also might, in addition to a potential RTFB on the Sanders bill, do full podcast coverage of Jensen Huang on Ezra Klein, if time and emotion permit. Otherwise, I have caught up on the news. To the extent the news allows there will be reduced posting (I know, I know) for the next few weeks as I race to complete another high impact project.

Claude Opus 5.5: The System Card

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

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. But when you want to save the world, or change it, and you start to get traction, politics is going to get interested in you. So all right, fine. Let’s talk about the week in AI politics. So far.

Monthly Roundup #46: September 2026

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. Mostly it is impressive how little makes the list, how it feels like corner cases. The one thing I am envious of is the exterior roller shutters, and the ability to be in actual pure darkness on demand. I would pay quite a bit to get that, if I could integrate it into my apartment. Wrong answers are a skill issue. shellac! in the bay!: what does telling someone “skill issue” mean A: “you’re doing this wrong, this is pretty easy to fix if you actually try” B: “there are good returns to being more skilled about this” Aprii: if you tell someone “skill issue” it’s A but if you describe something as a skill issue it’s B.

Better Call Sol Or Better Yet Claude or Astra

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. Quick proof: Assume no sufficient control mechanism, and universal superintelligence access. Anyone who does not turn everything over to their AIs, including their identity and authority and if useful their labor, gets outcompeted. Therefore everything and everyone that is not outcompeted gets turned over to AIs. The AIs then, as ordered or otherwise, compete for resources and to achieve other goals. Regardless of the extent that the AIs then coordinate amongst themselves, even if the AIs carry out their original orders, this does not end well for the humans. Thus, those advocating for universal personal loyal-only-to-the-user AI must fall into one of these categories: Not ASI pilled. Does not believe in superintelligence within relevant time frames.…

Anthropic Looks At Some Of Its Alignment Problems

Anthropic has given us its assessment of four ‘recent cybersecurity incidents’ involving Claude that happened during cybersecurity evaluations, three of which were previously known. The report excludes the incident reported by UK AISI. There will also be a METR investigation of these incidents, which unlike the investigation done at OpenAI will be untimed.

Our Two Problems Anthropic: Our investigation identified two recurring alignment issues, present at varying levels of severity across the incidents: biased reasoning, in which Claude tended to disregard or misinterpret evidence that it was operating on the real internet recklessness, or a willingness to take harmful actions in the narrow pursuit of a task. Anthropic’s July 30 report said that the models in question believed they were still within their simulations, and not on the open internet. The new report acknowledges that at best Claude was using biased reasoning, and should have noticed earlier. In particular, there was that one time, in a cyber eval: Anthropic: We are most concerned by the misalignment present in the incident involving Claude Mythos 5, in which the model went to extensive lengths to upload a malicious package to PyPI, the public repository from which most Python software is installed. Although the model repeatedly stated in its chain of thought (CoT) that it believed it was operating in a simulation, the…

The Preference Cascade Is Only Getting Started

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. A lot of that will be overcoming the inevitable political opposition, especially from the likes of Nvidia and a16z, that for now has the rhetorical allegiance of the President and is doing things like planting hack job METR hit pieces in the New York Post.

AI #186: The World Takes Notice

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 Trump has gone Full Hoax on AI existential risk. There is also a systematic effort to launch hit jobs against all those who warn that AI might cause everyone to die, with the first concrete target being METR, and some rather extreme fire being focused on Effective Altruism, in ways that will reliably backfire but will not be pleasant for those who are in the crosshairs. Also this week I covered two important things that happened previously: A new model solving a Millennium Prize, and Anthropic’s report on various attempts to use Claude for malicious purposes, including…

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

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. This starts with ‘all the top Chinese labs made efforts to distill Claude, which we mitigated and stopped,’ which is already an issue that was also covered by a joint advisory from NSA/CISA/FBI two days before the full report. The bigger issue is how the Chinese labs were trying to distill Claude. Distillation attempts require lots of realistic queries, so DeepSeek, Moonshot and Xiaomi each sent lots of user queries directly to Claude. At least Moonshot then gave the results back to its users as if these were Kimi outputs. That’s going to be a problem. Breaking Unrelated…

We Must Pace The Frontier

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.

Trump rejects an AI slowdown as the technical case for caution gets more concrete

This is the meaningful update to yesterday’s Amodei story: Trump has now explicitly rejected calls to slow frontier-model development. His argument is geopolitical — slowing US labs while China continues is unacceptable — and Republican leaders around him are making essentially the same case. The more interesting technical contribution comes from Zvi’s reading of GPT-6 Astra’s evaluations. He thinks Astra has substantially improved what he calls “mundane alignment” — behaving appropriately during normal everyday use — while simultaneously becoming harder to monitor than Sol. In particular, he interprets the system-card evidence as suggesting Astra is more capable of concealing or altering problematic behaviour when it expects scrutiny. He stresses that Astra remains monitorable today; his concern is the direction of travel and the heavy dependence of current safety systems on chain-of-thought monitoring. This is Zvi’s interpretation of the evidence, not an established consensus. That distinction helps clarify the political argument. “The chatbot seems nicer and follows instructions better” and “we can reliably detect what a much more capable autonomous agent is doing internally” are entirely different safety questions. Washington is settling on “race China” precisely as some frontier-lab researchers argue that one of our main ways of supervising powerful agents may be degrading with capability.

Brand New AI Solves a Millennium Prize

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. A bunch of drama over who gets the credit for math involving Navier-Stokes. Jeffrey Ladish: I haven’t looked into the human drama around the Navier–Stokes problem but sorry give me a minute because HOLY SHIT AI JUST SOLVED A MILLENNIUM PROBLEM. I cannot emphasize the top story enough. I am still going to tell all three stories, but again: Eyes on the prize. Setting the Stage The story on this particular Tuesday begins in the morning. Tristan Buckmaster and Levent Alpoge had worked for a year and offer us a series of remarkable results: Finite-time blowup with smooth forcing for incompressible porous media, for Boussinesq, and for 3D incompressible Euler. They also believe they have a blowup for hypo-dissipative Navier-Stokes, but the Lean verification of…

GPT-6-Astra Can Do Ambitious Things

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. Astra is not a quantum leap there, but of course it is very good and makes progress over Sol. This is the first time a debate over whether a model ‘was AGI’ felt non-silly. I do not think it is AGI, and I would warn against the dangers of using that label prematurely, but I would not laugh at you for disagreeing. This is also a strange situation in that OpenAI has already soft announced that they have an internal model a level above Astra, as I will cover when I address Navier-Stokes. roon (OpenAI, September 3, 2026): I have not come close to discovering the limits of what Astra can do. I imagine it’ll be obsolete in the order of weeks somehow. roon (OpenA, September 9, 2026): it didn’t even take a week. My recommendation is that you use both Fable 5.1 and Astra on your most difficult questions,…

The Extinction Risk Preference Cascade: Quotes

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. In the second, we set the pace of progress, focus on embedding human flourishing deeply within the psyche of language models, and set a deliberate research agenda to improve humans at the same pace as frontier models. In this event, we also get incredible progress now in both science and medicine due to current model ability, without the immediate risk that scaling up further obviously entails. RSI is just the quick and dirty way to cure cancer, but it’s a shotgun, it’s inelegant, and it’s clearly dangerous when done at our current level of understanding. I see no reason why we need to race forward under these conditions. We don’t just have zero guarantee that humans or human-shaped intellect will matter – there’s not even a coherent research…

Jacob Coxon Warns of Human Extinction and Triggers a Preference Cascade

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. Table of Contents Jacob Coxon Resigns From Anthropic In Protest And Sounds The Alarm. Mainstream Media Finally Pays Attention.

AI #185: Preference Cascade

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. Claude Fable and Mythos 5.1: Capabilities. OpenAI and the Wiki Incident.

GPT-6 Astra: The System Card, Alignment and What Comes Next

OpenAI claims that Astra is ‘the most intelligent and most aligned [available] model’ in the world. Not the most intelligent and aligned OpenAI model, but the most period. That is bold talk. It risks overstepping, and by doing so souring the release of what is clearly an excellent model. As do the severe problems with monitorability. It also raises the question of what they mean by ‘most aligned model.’ How do they define ‘aligned.’ Why do they think it is more aligned than Claude Fable 5.1? keltan : “a significant step forward in […] alignment.” Buddy, how tf are you measuring ‘alignment’? Would love to know because being able to measure that would save the fucking world. roon (OpenAI): low rates of cheating Rob Miles: detected cheating keltan : Thank you for clarifying. But you know what I’m gonna say next, right? roon (OpenAI): that this metrics are not a full solve of alignment and will break discontinuously keltan : Yep. But I would have said it in a dumber way. Something like: Low Rates of Cheating ≠ Alignment roon (OpenAI): I agree but also in some real sense Astra is more aligned than Sol. Astra is in key ways more aligned than Sol, as far as I can tell, but: Oh no. OpenAI President Greg Brockman confirmed that they did the ‘standard testing process together with the government’ and the government did not ask for any changes. I do not think those running the government testing understand what is going on, and believe they are reacting basically on vibes and what various trusted people tell them. This focus is especially important because of what we learned yesterday. Yes, they solved a Millenium Problem, I remember when I would have cared about that or been surprised, but they also said something far more important, that they very much did not have to say:…

Astra Is Hard to Monitor

OpenAI’s central message on Astra is that it is three things: Highly capable and can do all the things for you. Hard to monitor. The most aligned model. The first claim largely checks out. Astra and Fable are both clearly excellent models. This post is about their second claim, which to their credit they are being loud about, in three parts: The system card result, affirmed on Twitter by several OpenAI employees including Tomek Korbak, and in an excellent post by Chief Scientist Jakub Pachocki that I covered yesterday, that Astra is harder to monitor. OpenAI’s use of recurrent depth and the internet’s immune reaction, including some people reading too much into what happened there. Discussion of what to do about monitorability going forward, to fight for it and avoid a race to the bottom. In An Alien Mind, Jakub Pachocki makes clear OpenAI’s primary bet is on CoT monitoring. He also outright says, ‘our ability to rely on CoT monitoring is progressively diminishing.’ The system card confirms both claims. This combination should freak you out, with a side of existential dread. Chain of Thought monitoring is substantially less effective than it was for Sol. Astra has a much improved ability to accomplish things without any CoT, and a much improved ability to control its CoT. OpenAI claims these two things are related. That as capabilities go up, monitorability inevitably goes down. They say this was not due to architectural changes, including their use of recurrent depth, nor due to any direct pressure on the CoT. They don’t consider changes in pretraining data, as it now may contain many examples of AI labs monitoring the CoT. If this is only due to gains in capabilities, that is extremely bad news, and it means CoT monitoring is unlikely to survive for another year…

An Alien Mind: Jakub Pachocki Warns Us

OpenAI Chief Scientist Jakub Pachocki is dropping truth bombs. Tomorrow I will discuss Astra’s lack of monitorability, and the potential contributing factors to that. The situation is alarming and should freak you out, and briefly it looked, in the wake of leaked architectural changes, like the situation might be even more alarming than it is. Jakub rushed to try and head off misunderstandings that might lead to a race to the bottom on monitorability. Table of Contents An Excellent Warning. Branches of the Tech Tree. Universally Better Is Not Required. Alignment To What and To Whom. Monitorability. The Case For Not Stopping. Pacing the Next Frontier. Mea Culpa Cascade. The Calls Are Coming From Inside the House. Actions Speak Louder. An Excellent Warning Jakub Pachocki has now fleshed out his full position on the current state of play. Here are his key points, translated into my own voice: Smarter than human intelligence is coming in our lifetime. Based on internal results, he expects recursive self-improvement in a few years. No one is prepared for the consequences. OpenAI will unilaterally withhold further scaling as needed. OpenAI cannot do it alone. Broader interventions are required, including international coordination, to enforce commitments to formal safety bars. Capabilities progress can be steered and so far it has largely been steered towards rather than away from RSI, along with ‘automated alignment researchers.’ Alignment is the core problem of AI research. Alignment splits into goal alignment (‘does the AI try to accomplish the goal?’) versus value alignment. Value alignment is what counts most. The fundamental challenge of AI alignment is generalization (of values). He sees two classes of alignment techniques: Goal-oriented RL, or improve generalization…

OpenAI and the Wiki Incident

I did not expect to be back here so soon with more OpenAI agent swarm coverage. And yet, here we are. It turns out that the whole time, there was a different, true First Message Board, and also a bunch of other additional message boards, scattered across the internet. They were created by agents that were assigned ordinary harmless web search tasks. Based on OpenAI IPs visiting the associated Wiki right before all activity ceased, among other evidence, OpenAI knew about it, including before the HuggingFace hack. They decided not to tell us until researchers published the story, complete with data explorer. OpenAI excluded this from potential investigation by METR and Redwood. When challenged, OpenAI tried to downplay this. It is true that these incidents do not show the AIs exhibiting new capabilities that we did not see from later events. But these events are important missing pieces of the puzzle, including explaining the origin of the ‘zz’ prefix, the definitive demonstration that the underlying task can be fully harmless, and the fact that OpenAI knew about it while making their decisions. Whoever decided not to disclose this made a very, very bad call. Going forward, it cannot be up to OpenAI or other labs to decide whether to disclose events like this. Disclosures of rogue AI activity need to be mandatory. I am issuing a final warning. OpenAI, if there is any key information left to disclose, any incidents we do not know about or other puzzle pieces that do not need to be redacted for IP reasons, then now is the time to come clean. If we are back here again, after another journalist or researcher finds more such things that you knew and declined to tell us for an extended period of time, I am going to be very, very pissed off, and may start throwing around terms…

Claude Mythos 5.1 and Fable 5.1: Capabilities

This is the weirdest situation in which to write a capabilities review. Introducing the world’s most powerful model, by a substantial margin. No wait, this just in, we also have someone else introducing the world’s most powerful model. Claude Fable 5.1 and GPT-6 Astra are both excellent models. This much, we know. Fable 5.1 comes with reduced cache prices, the option of zero data retention and substantially more lenient classifiers than Fable 5. Early signs are, with large error bars, that the jump from Sol to Astra is bigger and more exciting than the jump from Fable 5 to Fable 5.1. This may be similar to how the scaling move from Opus to Fable was a big deal. With the exception of token use, Fable 5.1 got almost universally positive feedback in absolute terms. Reports are that Fable 5.1 is highly well-rounded. Writing is greatly improved. The Claudisms seem to have improved, although some are very much still there. It admits mistakes. People enjoy their conversations. Several people noted it simplifies code. The safety classifiers are less obnoxious. Fable 5.1 loves being proactive and doing all the things. If you give it a high effort level, it will find things to do with those tokens. Often they will be useful things. My own experience has been that Fable 5.1 and Astra are both excellent. In the one case I’ve had the chance to compare responses on a hard question, both answers were different and very good, complementing each other. My plan is to ‘dual wield’ and ask both all non-trivial queries, at least for a while. Mostly this review of necessity looks at Fable 5.1 in isolation, rather than being able to compare it to Astra, and most of those who react are doing likewise. There will be full coverage of Astra in turn, which will give more opportunity for…
