OpenAI releases mathematical work tied to 377 unsolved problems

7 OCTOBER 2026·2 MIN READ·7 SOURCES

OpenAI has published mathematical results produced by an internal model, in a repository listing 722 manuscripts across 372 families. Separately, Ynet reports that the work addresses 377 previously unsolved problems, a figure that describes problems rather than manuscripts or manuscript families.

OpenAI releases mathematical work tied to 377 unsolved problems

Key takeaways · 4

  • 01

    The repository lists 722 manuscripts grouped into 372 families; Ynet separately reports work on 377 previously unsolved problems.

  • 02

    OpenAI says it tested the model on approximately 4,000 problems after existing mathematical evaluations saturated.

  • 03

    The collection contains results at different verification stages, and not all have Lean formalizations.

  • 04

    The model has not been released publicly, so independent replication remains a limitation for assessing the reported work.

Evaluation and compute figures

OpenAI says it expanded its evaluations after the model’s performance on existing mathematical evaluations saturated, and that it posed approximately 4,000 problems to the model.[2] The evaluation figure is not the same as the 377 previously unsolved problems described in Ynet’s account of the published work.[2][3] OpenAI says the average result used compute equivalent to roughly three hours of ChatGPT Pro thinking, and the repository includes 10 summaries of the model’s reasoning.[1] Those figures offer some information about the work’s production, but do not by themselves establish the novelty or correctness of each result.

Verification is still in progress

Scientific American reports that many results had already been verified in Lean, which it describes as a programming language that validates proof logic.[4] The model that produced the work has not been released publicly.[4] MIT mathematician Andrew Sutherland told Scientific American that one-agent, one-shot claims should be treated as unverified until the model is released and results can be replicated.[4]

High-profile claims need scrutiny

Ynet reports that some papers concern challenges linked to three of the seven Millennium Prize Problems.[3] Scientific American reports that the work includes a claimed solution to the four-dimensional Kakeya conjecture and progress toward the Riemann hypothesis.[4] It also reports that mathematicians may need months to determine whether the proofs contain novel ideas or combine existing techniques.[4] OpenAI says it has consulted an independent advisory group on best practices and will fund workshops, conferences and special programs to help people understand major AI-produced results.[1]

For researchers and teams evaluating AI-generated technical work, the release offers a substantial body of material to inspect, but the reported problem count should not be mistaken for a count of independently validated breakthroughs. The model’s public unavailability and the collection’s varied verification status make careful review and reproducibility central to any decision to build on the results.

How this developed

  1. 7 October 2026

    Ynet reports that OpenAI’s release describes work on 377 previously unsolved mathematical problems, with coverage across several fields and challenges linked to three Millennium Prize Problems.

  2. 7 October 2026

    Francesco Maggi said he had heard that something like 400 AI-generated proofs might be released on a public server; a Wired-quoted speaker said no release time had been set.
