OpenAI says its agents cracked it in 88 hours. The mathematician that the firm called first says he was pressed to drop his Anthropic co-author.

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.
