Hallucination in AI: What It Is and How to Prevent It

AI hallucination happens when artificial intelligence systems generate false, inaccurate, or completely fabricated information while appearing confident and coherent. You ask a chatbot a question, and it gives you a detailed answer that sounds perfectly reasonable. The only problem? It’s wrong, and the AI invented it entirely. This isn’t a minor glitch. It’s one of
