OpenAI's unreleased Astra model solves 10 open math problems

OpenAI says an internal version of its next model, Astra, produced machine-verified proofs for 10 long-standing problems in math and theoretical computer science, including the first explicit non-sofic group. Total inference cost was roughly $2,000 at Sol API rates, with Lean 4 certificates on GitHub.
