OpenAI has announced a solution to the Navier-Stokes problem, one of the seven Millennium Prize problems, reportedly using an internal model more advanced than GPT-6 Astra. The claim is met with significant controversy, with accusations that OpenAI's solution may have been influenced by the work of independent researchers Tristan Buckmaster and Levon Alpashidji, who claim to have been working on related problems using AI models including Codex.
“the Navier-Stokes equations use Newton's Second Law of Motion, F equals MA, to describe how fluids move.”
“Crucially, Levon and Buckmaster did not find a solution to Navier-Stokes, but they did find novel solutions to related problems that could be viewed as a stepping stone to the Millennium Prize problem.”
“According to Buckmaster's telling, Sebastian Bubeck from OpenAI informed him on Sunday that they had solved Navier-Stokes and wanted to discuss publication.”
