SITUATION EXPLAINED: OpenAI says an unreleased model solved the Navier-Stokes Millennium Prize Problem in 88 hours. • The result: an initially smooth fluid at rest, with a smooth external force and finite energy throughout, does develop a singularity in finite time. The solution is a vortex spiraling inward and elongating like spaghetti • OpenAI has been training the internal model since August 28, less than two weeks, and calls it significantly more capable than Astra. Training is still…

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.
