Those are very inaccurate descriptors. A lie is an intentional deception, which is impossible for GPT. It "believes" that it "knows" something about the world, which happens to have been made up wholesale by its "subconscious" (obviously I know it's not a human brain). That is pretty much a hallucination by definition, applied to a non-human "intelligence". Besides, > it's presenting wholesale fiction as fact both coherently and with absolute confidence That is not in any way distinct from perceiving reality incorrectly. It is a symptom common to both skilled lying and hallucination.
