OpenAI announced a solution to the 90-year-old three-dimensional Navier–Stokes problem on Tuesday. The ChatGPT maker used an internal OpenAI system to generate the solution. It took 88 hours and 10,000 concurrent agents. OpenAI confirmed that it does not plan to claim the official Millennium Prize reward, but the result is shown to demonstrate the capabilities of its AI systems. However, the claim has already raised questions from mathematicians.
