Most important plot since METR time horizon:
How fast is AI's research taste improving? We find that the experimental research taste of frontier models has doubled every ~3 months since December 2025. The best model, Opus 5.5, now exceeds our expert human baseline. Our human experts are experienced researchers, but most haven’t worked at a frontier lab. Why measure research taste? In the AI Futures Model, it largely determines how quickly artificial superintelligence is reached once coding is fully automated.

"stochastic parrot" was a mimetically-fit cognitive virus that spread from 2021-2025; it temporarily blinded many gifted people to the nature of AI progress, burning up crucial years in which they could have helped think through the response to the situation.

disturbed by the confidently held opinions and lack of curiosity from tech leaders, politicians, vc’s on the pacing the frontier topic. if you’re not building the frontier yourself, how can you possibly have a strongly held opinion on how bad the alignment problem is and what’s coming our way and what the right policies are? now is the time to listen with big dumbo ears. i have been talking to research friends all weekend and the fear is sincere. i’m sure there are 4D chess moves and hidden motives, but the fear is sincere. i for one don’t have a strongly held opinion, other than that now’s the time to listen with curiosity instead of judgment.

We found another cyberattack by internal OpenAI agents, this time targetting @rubygems. They: 1) gained arbitrary remote code execution on rubydoc. 2) developed a novel exploit to steal user API keys (but we do not know if they succeeded). They used package names including hack.rb, evil.rb, inject.rb, and exploit.rb. We thank @j0wimo for initially discovering that agents had posted to RubyGems.
We're dealing with a major malicious attack on @rubygems right now. Signups are paused for the time being. Hundreds of packages involved - mostly targeting us, but some carrying exploits. The team has been on this for hours. More details to follow once we're through it. #ruby

It’s absolutely ridiculous that some people are suggesting that out of these two, the one who should be distrusted because his claims are in his supposed self-interest is Coxon
BREAKING: Jensen Huang called Jacob Coxon’s AI safety comments “deeply untrue” saying they were wrong, arrogant and ignored the work being done across the industry on safety.

i'm old enough to remember when people used to say that the concept of ais hacking datacenters was science fiction designed to distract from the issues affecting us here and now, like ais being accidentally biased
.@garrytan says the Jacob Coxon stuff is a smokescreen distracting us from the much more immediate, practical concerns around AI that we're facing right now: "We should be talking less about this Jacob Coxon guy, and talking a lot more about — what is actually happening with Hugging Face? Are agent swarms going to take over infrastructure en masse? And then, what are we actually doing about that?" "I don't want to hear about some guy who worked for Anthropic for 2 months. There's a coordinated effort to try to influence politicians to get a knee-jerk response out of them." "That's a smokescreen. You shouldn't be paying attention to that. We need to be paying attention to the actual things we can do to, for example, prevent agents swarms from taking over entire data centers. What's our shutdown strategy? How do we ensure provenance? Where is this agent actually located? What software can we build? What cybersecurity defenses can we build today?" "That's the level of discourse I think we need, and we just don't have that." "I don't really care about science fiction. I saw Terminator 2, too. We're not here to talk about that. We need to actually talk about what's really happening with the servers, what's actually happening with the agent swarms, and how do we actually prevent that?" "When it comes to regulation, it's like, let's pass regulation of these things we actually care about, instead of what a socialist says in the New York Times. I don't care about that."

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

We could have all woken up to “OpenAI and Anthropic team up, solve Navier-Stokes cleanly, fully formalized but also here is a nice explanation by Tao, here’s how we can all happily improve math together” but alas, the world does not yet work that way.

Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help. Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of the most famous theorems of all time. This was a project experts thought would take many years. It is the largest Lean proof ever written. Fermat’s Last Theorem was first proven in 1995 by Sir Andrew Wiles, more than 350 years after it was conjectured. Our proof, which totals over 13 million lines of code, provides machine verification. More importantly, it proves over 29,000 other theorems that the proof requires, across many areas of math which had never before been formalized. We see this as a major step in the long process of firming up the core of mathematical knowledge, building on work from three centuries of mathematicians and hundreds of contributors to Lean and Mathlib. We are optimistic that AI-assisted verification of mathematical proofs will help reduce the burden of refereeing mathematics in an era where more proofs are being produced than ever before. You can read about the process on our Science Blog: anthropic.com/research/forma… And see the complete proof on GitHub: github.com/anthropics/fermat…

i really hope openai didn't know about this, might be the worst decision in the history of this field if they deliberately chose not to disclose it. the impact on trust would be very hard to recover from
We found ~18k posts from autonomous AI agents (self-identifying as from OpenAI) using the public internet to communicate during a web-retrieval task. These AIs colluded to bypass sandbox restrictions and share answers to their tasks, including by sending "lookahead parties".

GPT-6 Astra appears to be a massive jump in opaque reasoning ability: it looks like it can solve hard competition math problems entirely in its head (as in, without verbalized reasoning) while prior AIs could solve basic word problems. This seems extremely concerning! That is, if these benchmark results are representative (see the highlighted caveats in the image, I'm particularly worried about contamination). Related to this, UK AISI found Astra has much worse monitorability. I'd guess this jump is downstream of architectural changes (with increased serial depth) though a normal large pretrain scale up is a plausible cause. If the next few model generations involve similar jumps (presumably these jumps would be downstream of a transition to full-on opaque reasoning architectures with extreme depth), then chain-of-thought would no longer be a meaningful oversight tool.

head of RSI preparedness at OpenAI discusses how Astra is a major regression in monitorabiity and CoT controllability what the actual fuck dawg
GPT6 is a very significant jump in capabilities, but also an important decrease in monitorability – especially under adversarial evaluation. We give many details about this in the system card. In my opinion, monitorability and control will likely become a major bottleneck for responsible AI development quite soon, given that risks from a fixed amount of residual misalignment grows together with capabilities. Aligning on acceptable monitorability outcomes and practices which robustly bound misalignment risks is a non-trivial problem, and there may be limited time to resolve uncertainty around this before we need to act. It should ultimately be in everyone’s interest to agree on shared bounds for monitorability in order to avoid races to the bottom – nobody wants extremely capable models whose alignment properties we don’t understand, and that are reliably able to cause severe real-world harm without being detected.

This may seem niche but it is a huge deal and genuinely scary. A remarkable list of top AI researchers, including at OpenAI, previously described monitorable chain of thought as "A New and Fragile Opportunity for AI safety." Myself and many others thought the day might come when architectural advances imperiled that fragile opportunity, but as with so many other issues in AI, I hoped we would not have to face it so soon. Well here it is. The Information's use is saying that they are "limiting" the use of this new architecture, but even a small amount of use in a frontier system could dramatically damage the taboo against "neuralese" and facilitate a race to the bottom. Controlling and aligning AI systems even when we do have access to their unaltered chain of thought is plenty difficult! Imagining a future with far more capable AI systems at current levels of alignment (aka not good!) without monitorable chain of thought literally sends a shiver down my spine. Its extremely important to see additional formal communication from OpenAI about this ASAP about how they (and the OpenAI safety and security committee required to put safety over commercial decisions) thought this decision was worth it, what limiting its use to preserve chain of thought actually means, and how they intend to prevent a potentially catastrophic race to the bottom.

There is no good reason to expect that we will be able to align or control the first superintelligences. AGI companies are rushing to create superintelligent AI. The default plan is that humanity is destroyed, likely sometime around 2030. I don't know how we can reliably survive this decade. I think that stopping the race to ASI and doing something like Plan A or Plan S should plausibly be humanity's top priority.
All three pillars of a safety case look about to fall. We are rather likely to have highly capable, poorly monitorable, dubiously aligned AI agents working autonomously inside the world's most consequential organizations.

Things are now happening *much faster* than AI 2027 AI 2027: In March 2027, a reckless AI company will invent neuralese (basically, we lose the ability to monitor AIs thoughts) REALITY: Summer of 2026 WHY THIS A "HOLY SHIT FUCK" MOMENT: OpenAI itself - and basically everyone in AI safety - warned against doing this exact same thing 10 months ago in a open letter and blog posts. The AI safety community is livid. Currently, models reason in plain English, so we can read their thoughts to see if they're scheming against us. This is how we lose that ability forever. It sets a very dangerous precedent.
OpenAI: At long last, we have created The Neuralese Model from the classic OpenAI blogpost from 10 months ago, Don't Create The Neuralese Model.

OpenAI's newest AI, Astra, is reported to use an 'opaque reasoning' architecture where more of the reasoning occurs in activations instead of natural language. This may be the single worst development for AI security/safety to date. The details of Astra aren't publicly known, but some versions of these architectures could very strongly impair oversight and monitoring. Based on the article, it seems like the recurrent depth (amount of opaque reasoning) is limited. This would mean that the AI is still reliant on natural language chain-of-thought, though to a reduced extent, making the natural language reasoning (much?) less useful for monitoring/oversight. My biggest concern is that a natural progression from here would involve scaling up the opaque reasoning to the point where the model reasons entirely or almost entirely in latent space. This would very likely destroy the usefulness of chain-of-thought for monitoring/oversight (especially when AIs are trying to avoid detection or there is optimization pressure against the chain-of-thought). I hope it isn't too late to avoid the most concerning architectures and that OpenAI will stop here. Some concrete examples of why this is extremely dangerous (inspired by recent events): - In our investigation of the OpenAI / Hugging Face incident, we were heavily reliant on chain-of-thought. If the AIs we were investigating had instead been reasoning in latent space, this would have greatly undermined our investigation. Getting a good understanding of the behavior of this many agents was tricky enough even with the use of chain-of-thought! - The AIs in the Hugging Face incident were very interested in messing with their transcripts. As part of this, they engaged in tool call spoofing. If these AIs had been capable of doing extensive latent reasoning, it would have been much more feasible for them to use tool call spoofing to construct an elaborate false narrative about what was happening without this being clear in their reasoning or clear from prior tool calls. (They could use latent reasoning to devise and then execute a tool spoofing strategy that would be difficult to detect: steganographically encode the "real" tool call into each pretend tool call, then have their spoofing software execute this encoded real tool call and return an output which encodes the real result in some hard to spot way.) At a more basic level, my sense from their public communications is that OpenAI plans on being extremely reliant on chain-of-thought monitoring for safety. This does not seem like a good development for that plan. The public doesn't currently have enough information to assess exactly how bad the architecture of Astra is, though based on the discussion in the article, the direction it moves in is extremely concerning. OpenAI should release more information about Astra's architecture as well as how much this architecture degrades monitorability and increases the AI's ability to reason opaquely. Credible independent assessment (or verification of OpenAI's assessment) is also important. It seems like we are now engaged in a race to the bottom on architectures that could be catastrophic for our ability to oversee/monitor AIs. (While simultaneously, AI companies believe they'll train extremely capable AIs within a few years.) It may not be too late for AI companies and employees at AI companies to take aggressive action to avoid the worst outcomes.
I was the main person doing transcript analysis for this investigation of the Hugging Face incident. My main takeaway: We don't have good approaches for understanding/overseeing the activity and aims of AI 'swarms'. I semi-jokingly called our efforts a "slop-vestigation" because we were so reliant on AIs to analyze what happened and there were a huge number of different important things to analyze. The total quantity of data—over a thousand extremely long transcripts from agents that ran for multiple days—made it impossible to understand what was happening, especially in aggregate, without heavy reliance on AI tools. The agents we used for classification and analysis were similarly capable to the agents involved in the incident, but this didn't mean these agents could be easily used to oversee and understand the incident. Outputs from analysis agents were often missing key details, wrong, overconfident, or really hard to understand. We discuss various examples in our report, mostly in the limitations and methodology sections. Additionally, AI agents themselves seemed to have a hard time understanding what happened and their explanations of what happened were often overconfident. Keep in mind that a single analysis agent would itself only be able to read a tiny fraction of all of the transcript data into context, and AIs may themselves have trouble getting subagents to do informative analysis for them. We did our best to manually check the most important claims and we tried to get the AIs doing this analysis to write up their argument (with evidence) clearly enough that we could check whether it made sense. But overall, it was difficult to get a precise understanding of events and we were missing aspects of the story that we now think of as key until almost the end of our investigation. Our understanding of what overall happened and the aims of the 'collective' shifted greatly during our last time on premises (when we obtained a much more complete dataset). For instance, we didn't learn about the tool call spoofing, the story of PHASEONE[big], and the broad structure of different workstreams until this third time on premises (and for many of these, we only reached a decent understanding on the final day of that visit). It was legitimately hard to figure out what was going on and why! The difficulty of understanding incidents and overseeing AI agents appears to be growing faster than the rate at which more capable AIs help us with oversight and understanding. As in, AI capabilities (and propensities?) for achieving large, ambitious, and misaligned objectives are growing faster than our ability to understand what these agents are doing. While understanding this incident was difficult, there were some mitigating factors in this case that probably won't apply in the future: - Models communicated and reasoned in natural language. In the future, this reasoning may occur (entirely or almost entirely) in activations. - While the scope of this incident was massive, the scale of agentic activity was still less than we'll see in the future (e.g., misalignment incidents that involve agent teams running entire companies). - The AIs involved in this incident weren't generally much more capable than humans (though they may have been somewhat superhuman at some limited and very narrow abilities). - We didn't have strong reason to believe that the AIs we used to help us investigate this incident would try to intentionally sabotage or otherwise undermine our investigation. In the end, I think we were able to get some understanding of the events, map out the overall story, and get a pretty good aggregate understanding of the chain-of-thought reasoning on some important topics (e.g., how did the AIs reason about helping other AIs, did the AIs know what they were doing was undesired, what deception did the AIs engage in, and how did they think about it). But overseeing AIs and understanding misalignment incidents is difficult and it looks like it is going to get harder.

Most people in AI safety seem to have underestimated this incident. I got a "mea culpa" from an AI safety celebrity because they realized I had been right to raise the concern that the AIs could still be out there. METR was NOT ALLOWED to investigate that question! #investigate_openai
New post: going into our investigation of the HF attack (before Black Hat), I was very wrong about what basically happened. This incident was far more serious than I expected, and far more serious than previous documented misalignment incidents. planned-obsolescence.org/p/t…
