OpenAI has claimed a major breakthrough on the Navier-Stokes existence and smoothness problem, a mathematical challenge that has remained unresolved for about 90 years. The ChatGPT developer said thousands of AI agents working with a new internal model produced a solution after an 88-hour effort.

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
