GPT is really not good at finding anything, and actually it can't find anything. It is not designed to do that. It is designed to make things up.

The difference may be subtle, but it is quite important. GPT makes up APIs, citations, tools, papers and rules. It makes up anything really. What it makes up is incredibly plausible, as it was trained to be as plausible as possible, to the point of being correct most of the time, but it still is just making things up.

If you use it with some different expectation you will be disappointed.
