OpenAI proves Navier-Stokes forms finite-time singularity
OpenAI says an internal multiagent system produced an analytical proof, with a Lean formalization, that smooth three-dimensional incompressible Navier-Stokes flow can develop a singularity in finite time, establishing Millennium Prize statements C and D. Roughly 10,000 concurrent agents reached the result in about 88 hours after September 1, with Lean verification taking another 17 hours via GPT-6 Astra. OpenAI says it does not intend to claim the Millennium Prize for the result.
