jfischoff · x · 2026-08-31

Lanyon AI demonstrated the ability to generate formally verified scientific computing code using LLMs. The project produced approximately 32,000 lines of C code and 50,000 lines of Lean proofs for solving ideal magnetohydrodynamics (MHD) equations. Taking about 434 seconds, the process achieved end-to-end correctness guarantees, showing that LLM-guided software development can meet high reliability standards.
