A blog post shows that a formally verified Lean implementation of DEFLATE compression outperforms a pure-Rust implementation in both speed and compression ratio at typical levels. The author attributes this to the ability to safely let AI agents optimize the code, relying on the formal proof to guarantee correctness.
Pramaana Labs raised $27M in seed funding led by Khosla Ventures to apply formal verification (using the LEAN programming language) to improve AI reliability in high-stakes domains like law, drug discovery, and tax preparation.
