Fact-check summary

Verified against OpenAI's post 'Sharing AI progress in mathematics' (openai.com, 2026-10-06: IAS advisory group, GitHub release, Lean formalizations for many proofs, 10 reasoning summaries, ~3h ChatGPT Pro compute per result, workshops, responsible release) and the openai/math repository README (722 manuscripts, 372 families, ~4,000 problems posed, 'Some of the unformalized results could have issues'). All figures are OpenAI's own.

OpenAI publishes 722 math manuscripts from an unreleased internal model

OpenAI released 722 mathematical manuscripts, grouped into 372 result families, produced by an unreleased internal model. The papers are on GitHub, with Lean formalizations for many but not all of them, and OpenAI warns some unformalized results could have issues.

On October 6, OpenAI published 722 math manuscripts in 372 result families, produced by an unreleased internal frontier model, in a public GitHub repository. Many, but not all, come with Lean formalizations, and OpenAI says some unformalized results could have issues. The model was posed about 4,000 problems, and each result used roughly three hours of ChatGPT Pro thinking compute on average. OpenAI says it will fund workshops and conferences around AI-produced math results.

OpenAI has released a large batch of new mathematical results produced by an internal frontier model it has not released to the public.

722 manuscripts went up on GitHub. On October 6, OpenAI published 722 manuscripts grouped into 372 result families in a public GitHub repository, with PDFs, source files and protocols for revisions and citations. A family groups related papers, such as a principal result, companion arguments, consequences or alternative proofs.

Not everything has been machine-checked. OpenAI is sharing Lean formalizations, which let a computer check a proof, for many of the results, but not all of them. The repository says some of the unformalized results could have issues, and OpenAI says it will add more formalizations as it obtains them.

OpenAI disclosed how the results were made. The repository includes 10 abridged summaries of the model's reasoning, compute estimates and problem statistics. OpenAI says the model was posed about 4,000 problems over the evaluation, and that each result used roughly three hours of ChatGPT Pro thinking compute on average.

Mathematicians were consulted on the release. OpenAI says it worked with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study and followed its recommendations. It is exploring community-hosted alternatives to GitHub and says future releases will improve citations, exposition and presentation.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.

Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.

Any contribution is appreciated. If not, no pressure. Thanks for reading.
