OpenAI released 722 research papers containing AI-created solutions to math problems across various subjects. The source attributes the success to several factors: math solutions are often verifiable like code, mathematics overlaps with AI researchers' own work, and ample computing power lets the AI perform number crunching that would take humans years. A mathematician advising OpenAI on public disclosure calls these abilities "brute force and stamina."

An OpenAI insider who quit says the company is frenetic, with staff running on adrenaline and fumes. He weighed staying to push cultural change but judged the machine too fast for internal reform. He says launches have been cancelled and some reinforcement-learning training paused, but pauses are carefully scoped, and he rejects 'pacing the frontier' because safety means meeting criteria. Model release intervals fell from about 70 days to 11.
