AI Hallucination

Inaccurate or fabricated output presented as fact.

Technical Term

Full explanation

An AI hallucination is inaccurate or fabricated output produced by an AI system and presented as though it were fact.

Why this matters

It is the general technical failure. Brand Hallucination is the specific commercial version, and the difference matters when explaining what a brand can actually do about it.

Where this sits

AI Hallucination belongs to AI & Search Infrastructure, one of the seven layers of the Aingworth Glossary. The technical vocabulary behind the interfaces. Useful for understanding how the systems work, without becoming the center of the conversation.
