AI Hallucination

You might say

This AI travel guide sounds confident, but I do not want to trust the opening hours. Research the official website or reservation page online and include the source link and update date.

An AI hallucination is information a model generates that looks credible but is inaccurate, unsupported, or invented.An AI can invent venue hours, a nonexistent link, an outdated rule, or a function that is not in a project. Fluent wording is not evidence. An Agent can research changing external facts online, but conclusions still need official or original sources, tool results, tests, and human judgment.
