AI Hallucination

An AI hallucination is when a generative model states something false or fabricated as if it were fact, including invented citations, statistics, or details. It happens because models predict plausible text rather than verify truth.

Why It Matters

Hallucinations can misrepresent a brand or attribute wrong information to it in AI answers. Publishing clear, consistent, well-sourced facts about your business reduces the chance an engine invents or distorts them.

Common Mistake

Assuming AI answers about your brand are accurate. Inconsistent or sparse public information invites the model to fill gaps with guesses, so authoritative, consistent sourcing is a defense.
