I think hallucination is akin to encountering a problem on a test to which you don’t fully remember the right concept to solve it. You might attempt the problem with whatever little knowledge you can recall, but the answer is ultimately incorrect. Likewise, these LLMs exhibit such behavior when they hallucinate. I think what distinguishes the LLM’s hallucinations from humans is the confidence level. A human who is unsure of their answer might tell you that they’re not certain or they don’t know. LLMs like chatgpt, however, will just confidently make stuff up.
