In one sentence
A brand hallucination is when an AI answer states something false about a company, such as a feature, price, location or fact that does not exist.
What it means
Language models generate plausible text and can fill gaps with invention. Brands see it as invented features, wrong pricing, discontinued products described as current, or being confused with a similarly named company.
It is more likely when reliable information is thin, outdated or contradictory. Grounded answers (grounding) reduce it but do not eliminate it.
What to do about it
Keep a short list of facts that must be right and check answers against it. When you find an error, look for its source: an old page, a third-party listing or a confused entity. Correct the source, publish a clear statement of the fact, and re-check over the following weeks. No vendor offers a guaranteed correction request, so verify by re-testing.
Not every wrong answer is a hallucination in the strict sense. Some are accurate reports of an outdated source. The fix is different, so identify which one you have before acting.
