Anthropic's Frontier Red Team blog details a collaboration with Theorem Labs in which Claude proved security properties across 100+ real-world open-source libraries within weeks. Formal verification was previously limited to small codebases or required heavy expert effort. Separately, axiomxyz says it is building RL environments for AI-driven binary-level formal verification to accelerate defensive security work.
