OpenAI stated that it found a solution to the Navier-Stokes problem, which had remained unsolved for approximately 90 years. The company reported this in a blog post on Tuesday; earlier, The New York Times and Wired wrote about the announcement.

The problem is related to the motion of liquids and gases and is one of the seven Millennium Prize Problems. A reward of $1 million is offered for the solution to each of them.

The practical significance of the announcement cannot yet be assessed based on available data: the source does not contain the proof itself, independent verification, or confirmation from the prize organizers.
