OpenAI Released 722 Math Papers in One Night — And Mathematicians Are Shocked
Inside OpenAI's 722-Paper Math Drop: The Quasi-Riemann Hypothesis, Lean Proofs, and Why Mathematicians Are Furious TL;DR On October 6, 2026, OpenAI published 722 mathematical manuscripts on GitHub, grouped into 372 result families across 17 fields, from number theory and geometry to theoretical computer science and mathematical physics. It announced the release with a research post, and the repository went live around 6 p.m. ET. An unreleased internal frontier model produced the results. OpenAI says it was posed roughly 4,000 open problems, and that the average result used about three hours of ChatGPT Pro thinking compute. The headline claim is the "quasi-Riemann hypothesis": no zeros of the Riemann zeta function, or of any Dirichlet L-function, with real part above 7/8. That isn't the full Riemann hypothesis, which concerns 1/2, but a fixed zero-free half-plane would be a first. It has a Lean proof, and no independent expert confirmation yet. Verification ...
