Hallucination
A hallucination is an AI generated answer that sounds plausible but is false, invented, or unverifiable.
A language model generates text by predicting the most probable next word, not by verifying facts. Without a reliable source, it can invent a number, a quote, or a name with the same confidence as a correct answer.
For a brand, a hallucination can attach false information to your company. Clear, dated, well structured content reduces this risk by giving the model a reliable source to cite.
