LLM fans never seem very comfortable answering the question "How do you know it's correct?"
I'm a moderate fan of LLMs.
I will ask for all claims to be backed with cited evidence. And then, I check those.
In other cases, of things like code generation, I ask for a test harness be written in and test.
In some foreign language translation (High German to english), I ask for a sentence to sentence comparison in the syntax of a diff.
If you don't know anything about the subject area, how do you know if you are asking the right questions?
