OpenAI Releases 722 Math Manuscripts Solving Hundreds of Open Problems Through Reasoning Model

OpenAI has released 722 mathematics manuscripts from an unreleased frontier model, claiming solutions or substantial progress on hundreds of major unsolved problems in pure mathematics and theoretical computer science. The release, published to GitHub on October 6, 2026, represents 337 distinct mathematical results derived from posing approximately 4,000 open problems to the model. Each accepted result required an average of just three hours of ChatGPT Pro-equivalent thinking compute—a dramatic efficiency gain compared to OpenAI's earlier Navier-Stokes proof, which consumed 88 hours across 10,000 parallel agents at an estimated cost of $22.5 million.
