Summary

Anthropic had Claude generate mathematical proofs of correctness for existing code across 123 open-source libraries, producing roughly 180 million lines of proof code. The model caught bugs that years of testing had missed, with the goal of making formal verification as routine as standard testing.

Original excerpt

Anthropic had Claude generate mathematical proofs that existing code is correct, producing roughly 180 million lines of proof code for 123 open-source libraries. Along the way, the model caught bugs that years of testing had missed. Anthropic's goal: making formal verification with AI as routine as standard testing. The article Anthropic's Claude now writes code and proves it safe automatically appeared first on The Decoder.
