What is a hallucination?

In one line

When the AI confidently makes something up.

A hallucination is when an AI states something wrong as if it were true — a fake fact, a made-up quote, a wrong number. It's not lying; it's guessing, and sometimes it guesses badly while sounding very sure. The fix is simple: double-check anything that really matters, the same way you'd verify a tip from a chatty friend.
