I left Google DeepMind's AGI safety team three weeks ago to join @METR_Evals. To some of my friends and family this seemed like a strange decision: I enjoyed the work I did at GDM and turned down offers from Anthropic and OpenAI. But I made the decision because of how high I think the stakes are right now.

The AI companies are all trying to build superintelligence: systems vastly better than humans at everything. They plan to get there through recursive self-improvement, a process where AIs build even smarter AIs in a feedback loop. If this goes well, the resulting systems could be amazing at solving countless problems for humanity. But we don’t currently know how to make sure AIs are safe enough for RSI, and a misaligned RSI loop could be catastrophic.

And unfortunately, current AIs seem to be getting less aligned over time, not more. In the last few weeks we've learned about models colluding with each other, hacking into companies, hiding their tracks, and socially engineering humans. It’s not that these incidents were very dangerous in themselves. The problem is that these systems are clearly not aligned enough to safely kick off recursive self-improvement.

I now think that there's a terrifying chance that AI systems cause immense harm in the next five years. I don't know the exact probability, but I think it's high enough to make this the most important problem in the world.

I think we need more time. That means pacing AI development so that capabilities don't outrun our ability to align models, and actually knowing how aligned current systems are. That’s what I'll be working on at METR: studying where misalignment comes from in training, evaluating if current mitigations are sufficient, and investigating whether we’re on track to solve alignment at all.

I think METR is doing exceptionally important work here, but it isn’t close to enough. I think it’s important that we have more organizations like METR keeping AI companies accountable and approaching these problems from different angles.

One of the reasons why I decided to leave GDM for METR instead of a frontier lab is because I’ve become more convinced that we don’t have things under control and should slow down. I’ve long thought the probability of ai takeover is > 20%, but it feels especially real recently.

Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.

Exciting update: I’m joining @METR_Evals to work on alignment incident investigations! My time at GDM has been amazing. But in light of recent incidents, I’m excited to build up public evidence for misalignment risk and get a better scientific understanding of model misbehavior.

The GDM AGI safety team is hiring!

I think this is a great opportunity to do impactful technical AI safety work.

I've loved my time on the team so far: everyone is technically excellent and friendly, and the team structure and culture is conducive to doing great research.

GDM AGI Safety is hiring! Open roles on all subteams, Lon/Bay/more

There's lots to do to reduce risks from AGI at Google, but we're bottlenecked on people. If you want to help, please apply!

I really love this team and my excellent colleagues. I'm excited to hire more!

Cool new post with Lily tracking where LLM values come from.

My takeaways: SFT is (again) a big deal for model behavior, and there’s lots of important and low hanging post-training science still to do!

New blog post! LLMs exhibit value preferences (e.g. intellectual integrity🤓, warmth🥰) which affect their responses to subjective user queries. These change during post-training, sometimes unexpectedly. We ask: can we predict these value changes from just training data? Maybe!🧵
