Fields Medalist Jacob Tsimerman Announces Move to OpenAI for AI Safety

新智元 · wechat · 2026-08-22

Fresh Fields Medalist Jacob Tsimerman announced at his award ceremony that he will join OpenAI to work on AI safety—a snapshot of mathematics' current predicament.

The backdrop: AI is churning out math results. An unreleased OpenAI model refuted the unit-distance conjecture in May; in August OpenAI published 10 AI-generated discoveries across math and CS subfields. An Anthropic employee used Claude to construct perpendicular vector pairs on a 668-dimensional hypercube; another had internal Claude seriously attempt the Riemann hypothesis, yielding a new finding on a related problem. A closed-door summit of 40 mathematicians at OpenAI HQ featured a talk titled 'The End of Mathematics.'

The community is split: over 3,000 mathematicians signed the Leiden Declaration urging responsible AI use, while others want to reject AI outright. Critics note AI proofs are hard to understand and models can't identify which parts of an argument are truly difficult; some see mathematicians as 'canaries in the coal mine.' Organizer Bubeck sketched four futures—math as software engineering, as physics, as museum curation, or mathematicians pivoting to AI safety—with no consensus reached.
