Why are some AI models 'hallucinating' or making up facts?

Some AI models are like kids who tell stories they think are true, even if parts aren’t real.

Imagine you have a friend who tells stories after dinner. Sometimes they remember things correctly, but other times they make up new details or mix up events from different days. That’s kind of what happens with some AI models when they're answering questions, they’re telling stories based on the information they’ve learned, and sometimes those stories include made-up parts.

AI models learn by looking at lots of examples, like reading a huge book filled with many sentences. They try to figure out patterns so they can make sense of new things. But when they're asked something tricky or not exactly covered in their "book," they might guess the answer instead of knowing for sure.

This is why some AI models "hallucinate", they create answers that sound reasonable but aren't based on real facts. It’s like your friend adding a dragon to their story just because they think it makes the tale more exciting, even though there was no dragon in the original book.

Sometimes the made-up parts are easy to spot, and sometimes they're so clever you almost believe them, just like with your friend's stories! Some AI models are like kids who tell stories they think are true, even if parts aren’t real.
