oh but you see, it's "hallucination" when LLM is wrong and it's hype cycle fuel when it's correct. no, LLMs don't "hallucinate", that implies that this state is peculiar, isolated, triggered by very specific circumstances. LLMs bullshit all the time, sometimes they are right, sometimes not, the process that produces both types of response is the same. pushing for "hallucination" tries to obscure that. use of "hallucination" also implies that LLMs know something, they don't, by design. it just so happens that if they "get" things right, it's because it appeared in training material enough times to make an impression in model.

The wikipedia page you linked to actually states that the term is being pushed by industry (Google, Meta, OpenAI) and that its use is criticized by some researchers.
