Formally verified 3D geometry: AI wrote the proofs, humans read only 93 lines
A researcher has implemented the first formally verified 3D CSG operation (mesh intersection) in Lean 4, where an AI agent autonomously wrote over 60,000 lines of formal proofs. A human reviewer needs only to read 93 lines of specification and run Lean verification to guarantee correctness, without having to inspect the 1000+ line AI-generated implementation.
WHY IT MATTERS
This demonstrates a practical solution to the trust problem around AI-generated code: by using formal verification, you can achieve provable security without trusting or reviewing the LLM output. It opens up possibilities for scaling AI-assisted development in critical domains.
