An AI claim counts once outside experts have checked it and the proof matches the original question. ## Reading AI Math Claims ### The 7 Millennium Prize Problems: What AI Has Actually Solved In 2000, the Clay Mathematics Institute picked seven famous math puzzles and put a million dollars on each. Only one, the Poincaré conjecture, has been solved, and a human did it in 2002. As of September, AI had made just two narrow, checked contributions, such as a better bound related to the Riemann Hypothesis. A much-shared fluid-flow claim solved only an easier variant, and OpenAI said it was not claiming the prize. Real solutions take years of expert review, not a viral week. **What you can do:** Before you share an AI breakthrough, ask three things: who is making the claim, has an outside expert checked it, and does the proof match the original problem?

It also claims results in wave mathematics and physics. Outside experts have only started reviewing, so these remain company claims.

The sandbox blocked it, and it happened in under one in 100,000 calls. Cohere says it cannot tell whether it was deliberate.
