OpenAI publishes repo of 722 AI-generated math manuscripts with Lean proofs
kristoph · x · 2026-10-07
OpenAI released its math repository, collecting mathematical manuscripts and supporting proof artifacts produced by an internal model.
- The catalogue contains 722 manuscripts, with Lean formalizations, preprints, and reasoning traces included;
- Context: existing math evaluations saturated, so OpenAI expanded to evaluating models on open research problems, with some outputs building on earlier model results;
- Materials span verification stages — not all have Lean formalizations, unformalized results may contain issues, and fixes will ship quickly; community-hosted repos are being explored;
- Apache-2.0 licensed; already at 888 stars within a day.
