A math problem that stayed open for 90 years just got solved in 88 hours. Roughly one hour of AI compute for every year humans were stuck. The Navier-Stokes equations describe how fluids move. Weather forecasts, airplane wings, blood flow, and ocean currents all run on them. In 2000, the Clay Institute put a $1M bounty on one question about these equations, and until today only one of the seven Millennium Prize Problems had ever been solved. The open question was whether smooth fluid motion…

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.
