Dirac’s Conjecture (1970) (might) be resolved by this graph in the paper. This paper is part of a new research program in our group. We’ll b writing up a broader paper on methodology in AI-supported research in Econ theory and math (detailing this finding… and perhaps something else). Stay tuned!

New paper: public AI benchmarks don’t just measure progress—they shape what labs build. When scores move capital, labs rationally optimize toward the test, which can erode its value as a signal. This is the market-design problem I’ve been trying to convince a frontier lab to think about.
