Ten advances in mathematics and theoretical computer science

Simon Willison's WeblogPublished Aug 1, 2026

OpenAI used an internal model called Astra to solve ten longstanding mathematical problems with minimal computational cost, providing formalized proofs and detailed reasoning. This effort follows Anthropic's cryptographic research using Claude and highlights AI's growing role in advancing complex mathematics.
