No, they do not. That's not how LLMs work, and stating that it is betrays an absolute lack of understanding of the underlying mechanisms.
LLMs generate statistically likely sequences of tokens. Their statistical model is derived from huge corpora, such as the contents of the entire (easily searchable) internet, more or less. This makes it statistically likely that, given a common query, they will produce a common response. In the realm of code, this makes it likely the response will be semantically meaningful.
But the statistical model doesn't know what the code means. It can't. (And trying to use large buzzwords to convince people otherwise doesn't prove anything, for what it's worth.)
To see what I mean, just ask ChatGPT about a slightly niche area. I work in programming languages research at a university, and I can't tell you how many times I've had to address student confusion because an LLM generated authoritative-sounding semantic garbage about my domain areas. It's not just that it was wrong, but that it just makes things up in every facet of the exercise to a degree that a human simply couldn't. They don't understand things; they generate text from statistical models, and nothing more.
