What is LLM plus symbolic execution or formal verification? Definition and why it matters ================================================================================ The model generates properties, invariants or code; a solver or prover checks them, so the model's output is accepted only when a machine confirms it. Detail: PropertyGPT, Certora AI Composer and Olympix use this pattern for contracts. In ZK, the same idea underlies better.codes and Clean, where the Lean kernel judges AI-written proofs.
