Why does AI hallucinate?
An AI hallucination is a plausible but false output, or one that is not supported by the information available to a generative model.
- Hallucinations arise from how generative models work and cannot be removed completely through prompting.
- Sources, RAG, structured data and explicit answer boundaries can reduce the risk.
- The required control depends on the consequence and use of an error, not on how convincing the answer sounds.
