- Anthropic said it partnered with Theorem to use Claude for formal security verification.
- Claude was used to prove useful security properties at the assembly-code level across 123 open-source libraries; the introduction separately notes that mature, heavily tested software still contains bugs and that LLMs are increasingly adept at finding them.
Why it matters: For Anthropic and Theorem, the 123-library scope makes Claude’s role concrete: proving stated security properties at assembly-code level. The material change is the kind of output claimed—formal evidence rather than mere bug identification in mature software that still contains bugs.
