OpenAI's Astra model solves 10 open math problems for $2,000

An internal version of OpenAI's next major model, Astra, produced machine-verified proofs for 10 long-standing open problems in mathematics and theoretical computer science, at a total cost of roughly $2,000 at Sol API rates. Results include a construction of non-sofic groups and a disproof of Connes's rigidity conjecture.
