OpenAI wanted to see if its agents could solve a long unsettled math problem. After gobbling billions of tokens, it found a solution.

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.

OpenAI said Tuesday that one of its unreleased artificial intelligence models had solved a mathematical puzzle that has eluded mathematicians for generations, a claim that also drew a fight with rival researchers over credit.

A mathematician compared the feat to the history-making chess competition in which IBM’s Deep Blue computer beat Garry Kasparov in 1997
