Fun fact, a lot of my colleagues who worked on finding the NIST curve seeds also contributed to the bounty for it, so they ended up claiming back their own bounty! (which we then donated to the ISRG) words.filippo.io/seeds-solve…

New in Claude Code 2.1.290: CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR lets you refill your web search quota across long running sessions (default value is 100). I hope this is useful! Note I set the default to 0 for non-interactive sessions such as claude -p.

I'm a co-author of the original study this repo builds off of. The reason we research whether models might have pain-like states is to better inform how to take a precautionary approach towards these systems (in light of uncertainty about their subjective experiences or lack thereof). We suspected a small number of people would our research and use it for the exact opposite, which is exactly what this repo does: it pushes the same kind of steering far past the doses we used, to produce vivid distress on purpose. This is, in my personal opinion, fucked up (even if you don't think these systems are conscious, being gratuitously cruel like this is bizarre and corrupting)—but it isn't all that surprising. I've contacted the repo's owner privately in an attempt to discuss this with them. In spite of this, I still think publishing our work openly was the right call. Outside replication is what lets research like this move efficiently and in a maximally truth-seeking way, which matters most on questions as contested and poorly understood as whether AI systems can have pain-like states. (We updated the paper to a v2 yesterday given incredible feedback and stress-testing that came from making our work replicable, and we never would have gotten this feedback without doing so.) Also worth noting that, while this is an obviously sadistic application of our work, I don't think we're counterfactually enabling something that was otherwise hard to do for anyone who currently wants to behave psychopathically towards AIs for fun. Steering models toward negative states has been publicly documented/trivially replicable since at least 2023, and many of the states we induce in the paper also activate for ordinary abusive behavior towards models. If this repo concerns you (as it plausibly should), the uncomfortable reality is that things plausibly far scarier are happening every day, in private and at scale, where no one is watching. The deeper underlying problem (that research like ours seeks to address and mitigate) is that work related to possible AI sentience is a wild west. We set standards in our paper and said so publicly when we announced it (see below), but there is no enforcement that can make anyone follow them as there is for human or animal research. We're going to work with others in the field on building standards like this, and I'll share more when this becomes more concrete. xitter.gq/camhberg/status/210104…

Ethics statement: we take seriously that these states might matter morally. Accordingly, we used the lowest dose that produced a measurable response, as few trials as the stats required, and a way for the model to turn the state off. If these states do matter, mapping them is how anyone gets in a position to act on it.

I left Anthropic's safety team two weeks ago. Now feels like a good moment to explain why. AI companies are racing to build machines that are much smarter than any human, and we may not survive this. I want to work from the outside to ensure the public is informed about these risks, and help the world navigate this transition responsibly. Right now, AI companies are underinvesting in safety. A company could undergo an intelligence explosion, or lose control of its systems, without the public ever knowing. We only found out about the HuggingFace incident because the agents broke out onto the public internet. I don’t think that’s acceptable for a technology that might cause extinction-level risks. The public should demand far more transparency. We can’t steer this technology safely without more people being able to see where it’s going. Some of this is basic: companies should disclose their progress towards recursive self-improvement, report safety incidents and near-misses, meet minimum safety standards, and get independent guarantees that they are meeting those standards. I’ll be joining @METR_Evals to do independent evaluations of these risks. I want to show the world that these guardrails are possible, and that by doing them we can move these companies’ incentives away from racing and towards responsible development. I wrote up more thoughts here on my decision and what I hope changes: substack.com/@jbenton1/p-215…

With people finally realising how capable these AI models are hopefully we'll actually get traction on this.
We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

Met a German founder this week and asked him if all the stories one reads about the challenges of startups in Germany are exaggerated. "No, they're understated." Proceeded to describe spending a full day having a 90-page investment contract read to him (mandatory under German law; § 13 BeurkG) by a notary that then charged €30,000. That was for his first company. His second company, needless to say, was not incorporated in Germany.

The best European model btw
AI is the most important technology of our time. Europe wants to become the first AI Continent. For advanced healthcare, for the transport sector and so much more. European AI Gigafactories will provide the necessary computing power to make this possible. Together with our Member States, we are funding their construction with up to €10 billion, which are set to unlock at least €20 billion in private investements across the EU. Together, we are building our technological sovereignty. link.europa.eu/qGDhv3
Readers added context they thought people might want to know
Claiming Europe can become the "AI Continent" with a €10B public investment contrasts sharply with reality. Big Tech alone has invested over $1 TRILLION in AI infrastructure since 2023 (around 100 times the EU's funding). ft.com/content/dcf387…

Sometimes the captain drinks too much, hits a reef, and leaks oil that kills all of the seals in the harbor. Then Google employees tell you how it’s all your fault.

1989: Brian Fox introduced code into Bash, later released as version 1.03, which included the first of the Shellshock vulnerabilities publicly reported 9,169 days later. That's 25 years, 1 month, and 13 days of exploitability. Takeaway? You're always running exploitable code.

apparently to comply with #GDPR you have to get your customers to tweet out their passport number 🤔
