Language models predict likely-sounding text; they don’t check facts by default. In images and video, the equivalent is odd details like extra fingers or melting objects.
Example
A chatbot invents a feature that an AI tool doesn’t actually have.
Why it matters to you
Always double-check important facts, especially numbers, names and links.
