Hallucination

Hallucination in AI refers to when the system confidently generates information that is plausible-sounding but factually incorrect or completely made up. It's not intentionally lying, but rather generating text that fits the pattern of real information, even if it's baseless. A teacher using AI to generate quiz questions might find a question about a historical event that never happened, requiring careful fact-checking before using it in class. Always verify critical information from AI, especially for creative or factual tasks.
