OK, personally If a friend recommended me a library that didn't exist I would reply back to him "you made that up".

So, ChatGPT is "making stuff up".

To me hallucinating is a really similar term for "making something up". So the term works perfectly well for me.

I mean the definition on Google at least is: "an experience involving the apparent perception of something not present."

Isn't that what's happening? ChatGPT is experiencing (writing code using) the perception of something (the library) that is not present.
