OpenAI releases 722 mathematics manuscripts from an unreleased internal model
On 6 October 2026 OpenAI published 722 mathematics manuscripts grouped into 372 result families, produced mostly by an unreleased internal frontier model; some proofs have Lean formalizations, while others remain unverified.
OpenAI reports a forced Navier–Stokes singularity matching Clay C and D
On 8 September 2026 OpenAI published a 166-page writeup and Lean formalization arguing that a smooth, finite-energy 3D Navier–Stokes flow starting from rest, under a smooth force, blows up in finite time. That is Clay statements C and D, which have been part of the official Millennium Problem since Fefferman’s formulation. The search model was an unreleased internal system; GPT-6 Astra did the Lean step. Clay wrote on 11 September that the problem has “apparently been settled,” with formal evaluation still to come.
An unreleased OpenAI system produces an unforced 3D Euler blowup
While probing Millennium problems in early September 2026, OpenAI says a multi-agent run of an internal model more capable than GPT-6 Astra produced a finite-time singularity for unforced 3D incompressible Euler in about 50 hours.
