Anthropic’s Claude auto‑generates formal proofs for 123 libraries

Claude generated mathematical proofs confirming correctness of code in 123 open‑source libraries, producing ~180 million lines of proof code and catching bugs missed by years of testing. Proofs apply only under strict conditions: specific processor architecture, single‑threaded programs, inputs < 64 MB.

Benchmarks are the company's own; not independently verified.

Why it matters

Consider adding automated formal‑verification features powered by Claude for safety‑critical products.
