OpenAI announced that a team using one of its internal frontier models has solved the Navier-Stokes problem. However, the announcement has been mired in controversy.

The company says it has cracked the physics of fluids using AI, solving one of the toughest puzzles in mathematics.

Mathematicians at OpenAI showed that the Navier-Stokes equations, which describe how fluids flow, can sometimes “blow up.” But the massive result is not without controversy.

Prior to the announcement, rumors were circulating online among mathematicians over the proof’s origins—OpenAI has denied all allegations
