Anthropic uses Claude to write 180M lines of proofs, verifying 123 open-source libraries
The Decoder · rss · 2026-10-23
Anthropic had Claude automatically generate mathematical proofs that existing code is correct, producing roughly 180 million lines of proof code covering 123 open-source libraries.
- Approach: Claude auto-generates formal proofs verifying the correctness of existing code
- Scale: 123 open-source libraries, 180 million lines of proof code
- Result: The model caught bugs that years of testing had missed
- Goal: Making formal verification with AI as routine as standard testing
