OpenAI Astra Solves Ten Decade-Old Math Problems: Multi-Agent Reasoning, Lean 4 Certificates, and the New Frontier of AI-Driven Mathematics
OpenAI revealed its next major model family, Astra, by publishing ten solutions to long-standing open problems in mathematics and theoretical computer science — each with machine-checkable Lean 4 certificates. Covers the ten results across eight domains, the multi-agent long-horizon architecture, $2,000 total compute cost, the Leiden Declaration context, and what this means for the future of mathematical research.
