AI Concepts
Hallucination
Definition
When an AI model generates information that sounds plausible but is factually incorrect, made up, or not supported by its training data. Hallucinations are a known limitation of current language models and a key reason to verify AI-generated content.
In Plain English
When the AI confidently makes something up. It might invent fake statistics, cite books that don't exist, or give you wrong dates — all while sounding completely sure of itself. Always double-check important facts.
