OpenAI has shared a proposed solution to the Navier-Stokes existence and smoothness problem, one of the seven Millennium Prize Problems carrying a $1 million bounty. According to the company, the breakthrough was achieved by an unreleased AI reasoning model described as significantly more capable than Astra. The Navier-Stokes equations govern fluid dynamics and have remained unsolved for centuries. OpenAI's purported proof attempts to determine whether smooth solutions always exist for the mathematical equations in three dimensions. The submission is currently undergoing scrutiny by the broader academic and mathematical research community globally.
