OpenAI says 10,000 of its agents solved the 90-year-old Navier-Stokes problem in 88 hours, but one mathematician has challenged the claim.

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.
