OpenAI publishes 722 math manuscripts from an unreleased internal frontier model on GitHub, claiming results on the quasi-Riemann hypothesis, the Hodge conjecture for CM abelian varieties and more
On 2026-10-06 OpenAI published Sharing AI progress in mathematics and released openai/math (Apache-2.0): 722 manuscripts in 372 result families produced by an unreleased internal frontier model, drawn from an evaluation of ~4,000 open problems at an average of ~3 hours of ChatGPT Pro thinking compute per result, with 10 abridged reasoning summaries and Lean formalizations for many results. OpenAI notes unformalized results may have issues; none are peer reviewed yet.

Key Takeaways
- Scale: 722 manuscripts in 372 result families, selected from an evaluation of ~4,000 open problems
- Compute: ~3 hours of ChatGPT Pro thinking per result on average, same unreleased internal model and fixed procedure
- Checkability: 235 of 372 families link to Lean; formalization.yaml lists 162 papers with a formalized main result, checkable via Comparator
- Transparency: 10 abridged reasoning summaries (irrationality exponent of pi, Mahler conjectures, free group factors, etc.) plus revision/citation protocols shaped with the IAS advisory group
- Caveat: OpenAI says some unformalized results could have issues; nothing is peer reviewed yet and the model is not released
