OpenAI claims agent-produced solution to 90-year-old Navier-Stokes Millennium Prize Problem

OpenAI announced that a group of agents, running on a next-generation model it says is significantly more capable than GPT-6 Astra, produced a solution to the Navier-Stokes Millennium Prize Problem — whether smooth three-dimensional fluid motion described by the equations can break down, unresolved for roughly 90 years.

Mathematicians reacted cautiously: TaliaRinger said it's hard to celebrate given how mathematicians have been treated, and worries specifically about possible Lean kernel bugs in this proof — unlike with FLT, this is exactly the situation where verification reliability matters most.
