PROOF OF WORK
Anthropic's Claude formally verifies security properties across 100+ open-source libraries
Anthropic's Frontier Red Team, working with Theorem Labs, used Claude to formally verify security properties across more than 100 real-world open-source libraries in weeks — a scale previously limited to small codebases or heavy expert effort. It is one of the clearest demonstrations yet of frontier models doing machine-checked, adversarial-grade security work.
