OpenAI Forms Independent Math Advisory Group AGMAI to Review Model Results

OpenAI announced a collaboration with the independent Advisory Group on Mathematics and Artificial Intelligence (AGMAI), hosted by the Institute for Advanced Study, to advise on evaluating, reviewing, and releasing mathematical results generated by its internal models. OpenAI says its internal model has solved more than 100 long-standing open problems and has published a paper and Lean formal proof for the Navier-Stokes Millennium Prize Problem, though the results have not all been publicly released or independently reviewed. The move responds to mathematicians' concerns that AI companies are treating open problems as capability benchmarks, but the advisory group has no veto power over publication.
