A hallucination is when an AI model generates false or made-up information that looks true, such as a figure, a quote or a reference that doesn't exist.
Language models generate the most likely text based on what they learned; they don't look up a fact database. When they don't have the information, they may fill the gap with something plausible. To reduce the risk in professional use: answer from company documents (RAG), require the source of every answer, instruct the assistant to say it doesn't know when the information isn't available and have people validate answers that drive important decisions.
