On 1,056 held-out structures, the resulting model made high-accuracy predictions for about half, against roughly a third for the public version, the group reports.

OpenAI says AI agents resolved Navier-Stokes problem; formal review still ahead

OpenAI said on Sept. 8 that about 10,000 AI agents running an unreleased model found a finite-time singularity in the three-dimensional Navier-Stokes equations, which would settle a Millennium Prize problem. The proof was formalized in Lean. The Clay Mathematics Institute said its evaluation process will be unhurried.
