7.5 OpenAI Claims Breakthrough on Navier-Stokes Equations Amid Mathematician Skepticism

OpenAI claims to have made progress on the unsolved Navier-Stokes equations worth a $1 million prize, but mathematicians question how the breakthrough was achieved so quickly.

  • 10,000 AI agents running on proprietary OpenAI model found Navier-Stokes singularity in 3D
  • Proof formally verified in Lean programming language; resolves question persisting since mid-19th century
  • Simultaneously, NYU and Anthropic researchers resolved related problems using various AI models
  • Result generated significant discussion in mathematics community but remains contested
