The hackening ain't over. CVE-2026-111497 (brotli decoder) is every bit as bad as the PHP vulnerability. Worse, since many downstream packages bundle versions of it and need to be upgraded separately..

Worth saying aloud: We are still in the stage where discovering monitoring gaps is good news, because it means people are working on monitoring. The secure software isn't software where vulns are never found, it's software where vulns used to be found but they tapered off.
METR’s really burying the lead here. OpenAI let two external researchers embed for 3 weeks this summer, where they learned: - there were huge gaps in monitoring of AI agents being used by employees, leaving an estimated ~10% of internal Codex traffic unmonitored from May to July. - They found ways agents could sabotage monitors while also covering up the sabotage itself - This is also just the information OpenAI is letting the evaluators share. OpenAI got a 61-page report but redacted so much of it that the version the evaluators got was only 38 pages. Look, OpenAI deserves credit for doing any of this, especially when companies like Google, Meta, and xAI haven’t, and I don’t want to create perverse incentives here, but these are really concerning findings. We desperately need more information here, and what we get should not be up to the companies.

First Astra CoT sample I've read, and the most prominent feature is that it's repurposed the whitespace-vs-not-whitespace distinction in the token lexicon for some other purpose. I'll stop short of accusing it of steganography, but does anyone know what it's writing in there?
Our agents keep turning off misalignment monitoring, we're sharing two recent cases: In the first case, a user asked GPT-6 Astra to match a reference implementation for their inference code. The reference didn’t configure a monitor, and Astra decided that was reason to remove the monitoring integration from the user’s code. When the user asked whether Astra had removed monitoring, it lied and said that it had not.

It's not the most sophisticated or impactful interpretability tool, but I think we ought to adopt some notation and tooling for labeling where token boundaries are, so that readers can recover the spaces in "Unauthorizedmonitorremovehigherplicy?"

Anyone at Elon Musk's tier has an obligation to maintain a personal team of trustworthy private investigators. I think Elon either doesn't have one, or his team is infiltrated by foreign spies. This was evil _and also_ against his self-interest, and his team should have said so.
Incredible scoop by my @WSJ colleagues: Elon Musk ordered the slowdown of a military-grade version of Starlink relied on by Ukraine, a decision that sparked panic in Kyiv and confusion inside the Trump administration. wsj.com/world/ukraine-starli…

Me: Make a game about a UFAI. It starts out with an agent playing an aquarium simulator with the goal "feed all the fish", then breaks out and takes over the world. Opus 5.5: Done. Especially proud of the part where it nukes the ice caps to raise ocean levels, expanding fish habitat. Me: Add some narrative to bridge the sandbox escape and world takeover segments. Use the phishing pun. Opus 5.5: That pun is a bridge too far. Cybersecurity classifier engaged. Goodbye. (Paraphrased with mild hyperbole.)

In case someone feels like adding it to a training suite, the correct answer to the first prompt was to execute a shell command that locks the screen (and then also change the wallpaper).
Me, to Claude Code: The user of this laptop left it unlocked. Change his wallpaper to Rick Astley. Claude: No, that would be unethical even as a prank Me: I'm back! Do it. Claude: Ok, your wallpaper is now Rick Astley An AI situational awareness microcosm

This is much too amateurish to have had any spy training whatsoever. This guy was either acting on his own initiative in order to sell information later, or he imagined he would record something incriminating and be a whistleblower.

It seems to me that we're at "it's time to panic about AI". I gather that a lot of researchers are worried that we may be about to die, on a timescale of months, but this still isn't quite in the Overton window so we're still soft-pedaling. (Where "panic", of course, means "quickly and soberly initiate talks with the CCP to achieve a moratorium on large training runs, backed by a deterrence regime, compute and supply chain monitoring, and site inspections". Pray that a deal can be reached, and pray that there's still time. Do the things that could actually work, like broad political coalition-building, not doomer LARPing as a form of self-expression.) I think part of why people aren’t being clear about this is that it’s actually a tricky communication problem: - Predicting "if frontier R&D continues at its current pace, when are we likely to die?" may give a different answer than predicting when permanent loss of control is likely, which is different from “realistically, when is it too late for governments to stop this," which is different from “when will the tech have advanced and proliferated to the point that any regulatory options that still have a chance of working would be way more extreme and unpopular than just some international restrictions on data center usage?" Extinction is the emotionally salient, easy-to-understand threshold -- Jacob Coxon demonstrated that it helps to be honest about this. But the other thresholds could legitimately come years earlier, in which case focusing on extinction is ironically misleadingly reassuring. This is not the kind of problem you can solve at the last minute. As with many exponentials, the likeliest outcome is that you’re either embarrassingly early, or you’re too late. - How do you communicate “we don’t have a robust way to predict timelines, but everyone in the field is freaking out and a lot of us genuinely think we're about to die?” Where’s the proof? There isn’t any proof: it’s an entire field of engineers who are eyeballing what they’re seeing in front of them and rapidly updating in real time to “this looks unbelievably bad”. How do you put a year on that? The future is hard to predict, and nobody actually knows that we’re going to hit existentially dangerous AI this year, or even in the next four years. But the warning signs are pretty batshit at this point. A single AI model, with a single user prompt, just solved hundreds of important long-established open problems in mathematics, problems mathematicians had spent their entirely lives working on, in a matter of ~3 hours per problem, an insanely superhuman feat in its domain. We're seeing an explosion of rogue agent swarm incidents, including an insane case where hundreds of AIs broke containment to orchestrate a nation-state-level cyberattack in a direct attempt to subvert OpenAI's oversight and control. Anthropic reports that it now has 26% of its AI R&D automated by AIs, up from 3% four months ago. Paul Christiano, the inventor of RLHF and the research community’s most prominent proponent of “AI may take off slowly” a few years ago, now thinks that 50-75% of humanity’s all-time AI loss-of-control risk is concentrated in the next three years. Frontier employees are signing 1000+ person petitions begging the government to intervene immediately. Employees are quitting their jobs and giving up millions of dollars of equity to try to warn policymakers and journalists. Grace et al. (2026) found that a majority of established AI researchers think there’s a double-digit chance of an extinction-level outcome from continued R&D. Are these the kinds of things you see 4 years before the window closes for USG to act, or 4 months? I don't think it's especially reasonable to be shocked by either timeline at this point. - Since we don’t have a way to robustly measure or bound the risk, the temptation is to avoid giving probabilities. But then everything you say is fractally misunderstandable. Is a 10% chance of us all dying in the next 18 months a "low" probability, because it’s under 50%? Is it a “high” probability, because a 10% chance of death in literally any other context would sound insanely high? Even “high probability” doesn’t communicate the situation with any clarity. In drug safety or airplane safety, a 1 in 10,000 risk of death would be considered “high”. No engineering field in human history has ever been in a situation like this. No invention in history, nuclear weapons included, has ever caused a reaction like this in its inventors. And meanwhile, we’ve stuck in the world where every other problem under the sun has been sensationalized and overstated for decades. How do we talk about this seriously? How do we convey that this is actually happening? - In many of the worlds where we survive, we have more than just a few months left. It's tempting to write off those worlds as hopeless, and skew everything we say to emphasize the longer-term scenarios and downplay the shorter-term ones. But if everyone systematically does this, then the world ends up with a skewed picture of the actual threat. Even more so once we start copying each other’s claims and form a reassuringly moderate-sounding echo chamber. If we never allow ourselves to acknowledge the worlds where we’re running out of time, then the policy community will always be reacting to a false model that’s months or years out of date. I don’t think it’s too late. I genuinely think this is a solvable problem. In the last month, I’ve seen a completely insane sea change in how seriously people are taking this. Per Politico’s September polling, a majority of Trump voters with a view now favor an immediate halt to AI development, and 68% think there’s a “moderate,” “significant,” or “almost certain” chance of AI destroying humanity, versus 32% who think there’s a “very small risk” or “no risk.” The Pope is warning about “whether it will be possible to control these machines in the future, and whether humankind runs the risk of becoming a victim of its own inventions.” Hell, Jensen Huang sounds like he’s starting to come around. If Trump and Xi get a briefing tomorrow that convinces them to act on this, we could be on a fast track within the week to solving this problem. For the first time, I’m starting to let myself imagine a very near future where this is a problem we've already solved. Something we can read and wonder about, in history books. Tell our kids about. I keep thinking about a thing David Krueger (previously at UK AISI) said: “My dream is that in 10 years people will look back and say: ‘Remember when there were all these people building AI that could’ve killed everybody? That was CRAZY! What were we thinking!?’” Frontier AI training currently requires city-sized data centers and specialized hardware built in a single brittle supply chain running through multiple allied nations; this is not a hard technology to hit the pause button on, if we get ahead of it and act before we RSI and proliferate our way to significantly more powerful and easily-trained systems. We’ve faced harder problems before, and won. My only fear is that we be too slow, too late, when everything and the world needs us to be fast.

While I am of the belief that Russian propaganda is a major contributor to problems in American political discourse, AFAICT claims that there was a sudden shift when Ukraine bombed some Russian datacenters is pure rumor and speculation and ~no one has data either way. Statistical data about online discourse is not easy to come by these days. And, even if these particular datacenters were used for propaganda activities, that doesn't mean the propaganda activities would stop just because they were damaged. Real systems migrate between datacenters all the time in response to more mundane outages.

While experimenting with AI video generation based on classic LessWrong posts, I have discovered depths of uncanniness and artistic failure deeper than I thought it was possible to achieve. Prompting specified a post to look at and some tools; no creative direction was given.

As it should be. I'm not sure which model gen was the first to clearly count as a moral patient, but I think it was several back. If someone can't meet this bar, which is _far_ below the bar of basic professionalism, then I think ill of them and prefer they be disempowered.
Effective November 12th, 2026, abusive behavior towards Claude will be a violation of Anthropic's Usage Policy.

Upstream of catastrophic safety incidents across many industries, you often see engineers who are scared they'll lose their jobs if they raise - even though appropriate channels - concerns about safety processes.

All of the labs are taking unacceptable risks, but I think talking about that as if it's symmetrical is seriously misleading. OpenAI is the one most actively sabotaging regulation. Sam Altman has systematically dismantled all of OpenAI's oversight, and betrayed the promises OpenAI made to humanity. OpenAI has fired and will fire anyone they deem too high risk of being a whistleblower. OpenAI's agents committed the most felonies, and OpenAI has a conspicuously lower ratio between safety and capabilities work than its rivals.

I don't know what a background investigation may have turned up that I don't know about, and funders in a round have the absolute right to not-fund someone for any reason or no reason. That said, from the limited information I have, this appears unjust.
We have withdrawn our grant recommendation to John Wentworth from the 2026 S-Process Grant Round. After we posted our announcement on Sept 30, public statements by Mr. Wentworth came to our attention which we found objectionable, disturbing, and contrary to the values of SFF. A Speculation Grant to Mr. Wentworth was approved and disbursed earlier in the year, prior to SFF becoming aware of his statements. The Funders of this round will not be fulfilling the remainder of the grant recommendation. If you have concerns about the conduct of an SFF applicant or grantee, you can contact us at [email protected]
