OpenAI has published an AI-generated solution to the Navier-Stokes Millennium Prize Problem. The release includes a written solution and a formal proof written in the Lean theorem prover, which allows mathematical arguments to be checked by a computer.
The announcement is notable because it presents a machine-generated proof for one of the most famous open problems in mathematics. However, the existence of a formal proof in Lean does not by itself mean the solution has been accepted by the mathematical community.
The source is a single announcement from OpenAI. It does not include any independent verification or commentary from other researchers. The status of the problem remains unchanged until the solution is reviewed and accepted by experts. The writeup and Lean proof are available for examination, but the claim should be treated as unverified.
