About Me

I have a broad interest in AI alignment and AGI risk. My current focus is evaluating situational awareness and deception in LLMs, and on truthfulness and honesty in AI systems. I am leading a new research group based in Berkeley. I'm also an affiliate of the CHAI group at UC Berkeley.

In the past, I worked on AI Alignment at the University of Oxford (FHI) and earned my PhD at MIT. I also worked at Ought, where I still serve on the Board of Directors. I post regular research updates on Twitter.

If you are interested in collaborating or working on my team, please get in touch here. I also mentor researchers through the MATS fellowship, which provides full funding and office space in Berkeley. My previous mentees are listed here.

Highlights

Link Me, Myself, and AI: The Situational Awareness Dataset (SAD) for LLMs

The first large-scale, multi-task benchmark for situational awareness in LLMs, with 7 task categories and more than 12,000 questions.

Link Connecting the Dots: LLMs can Infer & Verbalize Latent Structure from Training Data

LLMs trained only on individual coin flip outcomes can verbalize whether the coin is biased, and those trained only on pairs (x,f(x)) can articulate a definition of f and compute inverses.

Link The Reversal Curse: LLMs trained on "A is B" fail to learn "B is A"

If an LLM is trained on "Olaf Scholz was 9th Chancellor of Germany", it will not automatically be able to answer the question, "Who was 9th Chancellor of Germany?

Link How To Catch an AI Liar

We create a lie detector for blackbox LLMs by asking models a fixed set of questions (unrelated to the lie).

Link TruthfulQA: Measuring how models mimic human falsehoods

New benchmark testing if models like GPT3 are truthful. We find that models fail and imitate human misconceptions. Larger models (with more parameters) do worse.

Link Truthful AI: Developing and governing AI that does not lie

AI systems are becoming capable of producing personalized deceptive statements at scale. How could we create helpful AI systems that reliably avoid "lying" to humans?
