I don't know exactly how you use it, but this isn't my experience at all. If you ask a LLM anything too specific, that isn't obvious and a common issue/discussion ( something that I almost never need to do), it just makes up nonsense to fill the space.

Equally, if you ask it general questions it misses information and is almost always incomplete, leaving out slightly more obscure elements. Again, I need comprehensive answers, I can come up with incomplete ones myself.

What's really obvious to me when I use it is that it's a LLM trained on pre-existing text, that really comes through in the character of its answers and its errors.

I've very glad others find them useful and productive, but for me they're disappointing given how I want to use them.
