What is Hallucination?
A phenomenon where an AI model generates incorrect or nonsensical information but presents it confidently as fact.
Short answer
In AI, a hallucination occurs when a model generates false, fabricated, or nonsensical information but presents it confidently as a factual answer.
Hallucinations occur because LLMs are probabilistic engines designed to predict the next word, not truth engines. They can fabricate citations, facts, or code that looks plausible but is entirely wrong. Mitigation strategies include RAG and grounding.
