OpenAI just released 722 AI-written math papers. Here are the 4 biggest claims in plain English. None have been confirmed by outside mathematicians yet. 1/ Quasi-Riemann hypothesis. Zeta has no zeros with real part above 7/8. It's not the Riemann hypothesis (that needs 1/2), but…↗

We’re releasing a broad range of new mathematical results produced by an internal frontier model. We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and publi…↗

Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help. Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of t…↗

New OpenAI repo with a Lean formalization by GPT-6-Astra proves that there are infinitely many pairs of consecutive primes whose distance is at most 186 github.com/openai/PrimeGa…↗

An internal version of Astra, our next major model, found new results across 10 long-standing open problems in math and theoretical computer science. The total token cost to find all 10 solutions? Roughly $2,000 at Sol API rates. Astra then formalized each argument in Lean. …↗
