FM-Agent: LLM-Based Hoare Logic Scales Formal Verification to Large Codebases
arXiv·high signal
Ding et al. present FM-Agent, which uses LLMs to perform compositional Hoare-style reasoning for formal verification of large-scale systems including compilers. The approach decomposes large systems into components with pre/postconditions and reasons about them separately, addressing the core challenge that automated formal reasoning doesn't scale. For builders shipping LLM-generated code, this offers a path toward provable correctness beyond test coverage.
