#4646 LLMs to "Prove" Software Functionality
#4646 LLMs to "Prove" Software Functionality #4646 Can coding specialized LLMs help "prove" software, either as a full system, or by subsystems and components individually? The short answer is no, a coding-specialized LLM cannot strictly "prove" software on its own —at least not in the mathematical sense of formal verification. However, yes, they can play a critical role in the formal verification pipeline when paired with dedicated automated reasoning tools. To understand why, it helps to separate formal mathematical proof from statistical probabilistic generation . 1. The Core Limitation: Probabilities vs. Logic Software verification requires proving that a system satisfies a formal specification under all possible inputs and execution paths . LLMs are probabilistic engines: They predict the most likely sequence of tokens based on patterns learned from training data. Because they lack an internal deterministic logic engine, they are prone to subtle l...
