Ship Your Interpreter
- Published: October 16, 2026Article: Kiran Gopinathan, Nikhil Pimpalkhare, Yiyun Liu, Zenna TavaresWe had LLMs write precise mathematical rules, or a formal semantics, for how a small programming language should behave.
- We then used Lean, a tool for checking mathematical proofs, to prove that the interpreter—the program that runs code written in that language—follows those rules even after being compiled into low-level instructions understood by a RISC-V computer chip.
- LLMs are growing alarmingly capable at finding and exploiting bugs in production software, with increasing reports of AI-assiste
