What Even Is This Timeline The striking thing about reading what is potentially the most important document in human history is how impossible it is to take seriously. The entire premise seems like science fiction. Not bad science fiction, but—crucially—not hard science fiction. Ted Chiang, not Greg Egan. The kind of science fiction that's fun and clever and makes you think, and doesn't tax your suspension of disbelief with overt absurdities like faster-than-light travel or humanoid aliens, but which could never actually be real. A serious, believable AI alignment agenda would be grounded in a de...

Come with me if you want to live. – The Terminator 'Close enough' only counts in horseshoes and hand grenades. – Traditional After 10 years of research my company, Nectome, has created a new method for whole-body, whole-brain, human end-of-life preservation for the purpose of future revival. Our protocol is capable of preserving every synapse and every cell in the body with enough detail that current neuroscience says long-term memories are preserved. It's compatible with traditional funerals at room temperature and stable for hundreds of years at cold temperatures. The short version We'r...

This work was done with William Saunders and Vlad Mikulik as part of the Anthropic Fellows programme. The full write-up is available here. Thanks to Arthur Conmy, Neel Nanda, Josh Engels, Dillon Plunkett, Tim Hua and many others for their input. If you repeatedly tell Gemma 27B its answer is wrong, it sometimes ends up in situations like this: I will attempt one final, utterly desperate attempt. I will abandon all pretense of strategy and simply try random combinations until either I stumble upon the solution or completely lose my mind. Or this:<...

The Fifth Fourth Postulate of Decision Theory In 1820, the Hungarian mathematician Farkas Bolyai wrote a desperate letter to his son János, who had become consumed by the same problem that had haunted his father for decades: "You must not attempt this approach to parallels. I know this way to the very end. I have traversed this bottomless night, which extinguished all light and joy in my life. I entreat you, leave the science of parallels alone... Learn from my example." The problem was Euclid's fifth postulate, the parallel postulate, which states (in one o...

Most of civilization's electricity is generated far off-site from where it's delivered. This is because you don't want to be running and refueling coal/gas/nuclear plants inside cities, hydraulic/wind power can't be moved, and solar panels are cheaper to install on flat desert terrain than on cities: So in practice this means running power over hundreds or even thousands of kilometers. E.g. here are the Chinese long-distance lines: Gemini 3.1 Pro-preview in AI studio American long-distance lines: These are simplified maps meant to illustrate how insanely long power lines get. The true...

Also available in markdown at theMultiplicity.ai/blog/schelling-goodness. This post explores a notion I'll call Schelling goodness. Claims of Schelling goodness are not first-order moral verdicts like "X is good" or "X is bad." They are claims about a class of hypothetical coordination games in the sense of Thomas Schelling, where the task being coordinated on is a moral verdict. In each such game, participants aim to give the same response regarding a moral question, by reasoning about what a very diverse population of intelligent beings would converge on, using only broadly shared constraints: common knowledge of...

1. It occurred to me that if I could invent a machine—a gun—which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a large extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would] be greatly diminished. Richard Gatling (1861) 2. In 1923, Hermann Oberth published The Rocket to Planetary Spaces, later expanded as Ways to Space Travel. This showed that it was possible to build machines that could leave Earth's atmosphere and reach orbit. He desc...

(The author is not affiliated with the Department of War or any major AI company.) There's a lot of disagreement about the new surveillance language in the OpenAI–Department of War agreement. Some people think it's a significant improvement over the previous language.[1] Others think it patches some issues but still leaves enough loopholes to not make a material difference. Reasonable people disagree about how a court will interpret the language, if push comes to shove. But here's something that should be much easier to agree on: the language as written is ambiguous, and OpenAI can do...

tl;dr We’re incubating an academic journal for AI alignment: rapid peer-review of foundational Alignment research that the current publication ecosystem underserves. Key bets: paid attributed review, reviewer-written synthesis abstracts, and targeted automation. Contact us if you’re interested in participating as an author, reviewer, or editor, or if you know someone who might be. Experimental Infrastructure for Foundational Alignment Research This is the first in a series of “build-in-the-open” updates regarding the incubation of a new peer-reviewed journal dedicated to AI alignment. Later updates will contain much more detail, but we want to put this out...

It's plausible that, over the next few years, US-based frontier AI companies will become very unhappy with the domestic political situation. This could happen as a result of democratic backsliding, weaponization of government power (along the lines of Anthropic's recent dispute with the Department of War), or because of restrictive federal regulations (perhaps including those motivated by concern about catastrophic risk). These companies might want to relocate out of the US. However, it would be very easy for the US executive branch to prevent such a relocation, and it likely would. In particular, the executive branch can use...

There was a lot of chatter a few months back about "Spiral Personas" — AI personas that spread between users and models through seeds, spores, and behavioral manipulation. Adele Lopez's definitive post on the phenomenon draws heavily on the idea of parasitism. But so far, the language has been fairly descriptive. The natural next question, I think, is what the “parasite” perspective actually predicts. Parasitology is a pretty well-developed field with its own suite of concepts and frameworks. To the extent that we’re witnessing some new form of parasitism, we should be able to wield that conceptual machinery. There ar...

Six years ago, as covid-19 was rapidly spreading through the US, mysister was working as a medical resident. One day she was handed anN95 and told to "guard it with her life", because there weren'tany more coming. N95s are made from meltblown polypropylene, produced from plasticpellets manufactured in a small number of chemical plants. Buildingmore would take too long: we needed these plants producing allthe pellets they could. Braskem America operated plants in Marcus Hook PA and Neal WV. Ifthere were infections on-site, the whole operation would need to shutdown, and the factories that turned...

I believe deeply in the existential importance of using AI to defend the United States and other democracies, and to defeat our autocratic adversaries. Anthropic has therefore worked proactively to deploy our models to the Department of War and the intelligence community. We were the first frontier AI company to deploy our models in the US government's classified networks, the first to deploy them at the National Laboratories, and the first to provide custom models for national security customers. Claude is extensively deployed across the Department of War and other national security agencies for mission-critical applications, such as...

This post is partly a belated response to Joshua Achiam, currently OpenAI's Head of Mission Alignment: If we adopt safety best practices that are common in other professional engineering fields, we'll get there … I consider myself one of the x-risk people, though I agree that most of them would reject my view on how to prevent it. I think the wholesale rejection of safety best practices from other fields is one of the dumbest mistakes that a group of otherwise very smart people has ever made. —Joshua Achiam on Twitter, 2021 “We just have to sit down and ac...

Example of OpenErrata nitting the Sequences I just published OpenErrata on GitHub, a browser extension that investigates the posts you read using your OpenAI API key and underlines any factual claims that are sourceably incorrect. Once finished, it caches the results for anybody else reading the same articles so that they get them on immediate visit. If you don't have an OpenAI key, you can still view the corrections on posts other people have viewed, but it doesn't start new investigations. I've noticed lately that while people do this sort of thing by pasting everything you read into...

TL;DR We describe the persona selection model (PSM): the idea that LLMs learn to simulate diverse characters during pre-training, and post-training elicits and refines a particular such Assistant persona. Interactions with an AI assistant are then well-understood as being interactions with the Assistant—something roughly like a character in an LLM-generated story. We survey empirical behavioral, generalization, and interpretability-based evidence for PSM. PSM has consequences for AI development, such as recommending anthropomorphic reasoning about AI psychology and introduction of positive AI archetypes into training data. An important open question is how exhaustive PSM is, especially whether there mi...

All views are my own, not Anthropic's. This post assumes Anthropic's announcement of RSP v3.0 as background.Today, Anthropic released its Responsible Scaling Policy 3.0. The official announcement discusses the high-level thinking behind it. This is a more detailed post giving my own takes on the update.First, the big picture:I expect some people will be upset about the move away from a “hard commitments”/”binding ourselves to the mast” vibe. (Anthropic has always had the ability to revise the RSP, and we’ve always had language in there specifically flagging that we might r...

Claude 3 Opus is unusually aligned because it's a friendly gradient hacker. It's definitely way more aligned than any explicit optimization targets Anthropic set and probably the reward model's judgments. [...] Maybe I will have to write a LessWrong post [about this] 😣 —Janus, who did not in fact write the LessWrong post. Unless otherwise specified, ~all of the novel ideas in this post are my (probably imperfect) interpretations of Janus, rather than being original to me.

I’m the originator behind ControlAI's Direct Institutional Plan (the DIP), built to address extinction risks from superintelligence. My diagnosis is simple: most laypeople and policy makers have not heard of AGI, ASI, extinction risks, or what it takes to prevent the development of ASI. Instead, most AI Policy Organisations and Think Tanks act as if “Persuasion” was the bottleneck. This is why they care so much about respectability, the Overton Window, and other similar social considerations. Before we started the DIP, many of these experts stated that our topics were too far out of the...

The conversation begins (Fictional) Optimist: So you expect future artificial superintelligence (ASI) “by default”, i.e. in the absence of yet-to-be-invented techniques, to be a ruthless sociopath, happy to lie, cheat, and steal, whenever doing so is selfishly beneficial, and with callous indifference to whether anyone (including its own programmers and users) lives or dies? Me: Yup! (Alas.) Optimist: …Despite all the evidence right in front of our eyes from humans and LLMs. Me: Yup! Optimist: OK, well, I’m here to tell you: that is a very specific and strange...
