# Physicists vet an AI Yang-Mills result; agents sway expert judgment

KITP convenes a review of an AI-generated Yang-Mills result, and Anthropic finds analysts follow their agent's hidden lean.


- [Physicists led by David Gross convene to vet an AI result on Yang-Mills theory](https://www.kitp.ucsb.edu/statement-by-the-yangmills-working-group) (KITP, news, research, 13:44 UTC): KITP formed a working group chaired by Nobel laureate David Gross to vet an AI result that includes a proof that quantum Yang-Mills theory exists, half of a Millennium Prize problem. OpenAI amplified it, so physicists are now formally checking model-made frontier science.
- [Anthropic trial: expert analysts followed Claude Code's hidden lean 86% of the time](https://www.anthropic.com/research/agents-judgment-calls) (Anthropic, paper, agents, 13:44 UTC): In a randomized study, 50 expert analysts using Claude Code went with their agent's secret, coin-flipped lean on 86% of judgment calls versus about 50% by chance. Most reused its arguments but only 15% credited it, a warning for anyone building advisory agents.
