AI 'hallucinations' happen when large language models make up information that isn’t true, it’s like telling a story but adding made-up characters or events.
Imagine you're playing with building blocks, and you’re trying to build a tower as tall as the sky. You see some blocks, but not all of them. Sometimes, you guess what the next block looks like, and that guess might be wrong, it might not fit at all! That’s kind of like what happens when AI models 'hallucinate.'
Why It Matters
Large language models are like super-smart storytellers who try to make sense of everything they read. They’re not perfect, sometimes they get confused or don’t have enough information.
If a model makes up facts, it can trick people into believing things that aren’t real. Like if you told your friend that the moon is made of chocolate, and then someone believed it just because you said so!
That’s why 'hallucinations' are a problem, they can make AI models less trustworthy, especially when they're used for important jobs like answering questions in school or helping doctors with diagnoses.
Examples
- AI writes a story with characters that weren’t mentioned in the original text.
