I don't really use the llms but I do enjoy pasting chunks of my code into free models with the question: what is wrong with this?

That way it hs no context from writing it itself nor does it try to improve anything. It just makes up reasons why it could be wrong. It goes after the unusual parts it would seem which answers the question reasonably.

Perhaps more sophisticated models will find less obvious flaws if that is the only thing you ask.
