Why are many AI models trained on public internet data?

Many AI models learn by reading lots of information from the internet, just like how kids learn by listening to stories.

Imagine you're learning to read, and someone gives you a big book with every story ever told. That would help you understand words and sentences better, right? Well, AI models are like that, they need a lot of examples to get good at understanding language.

Think of the internet as a giant library with millions of books, videos, and messages. When AI models learn from this library, they get to see how people write, talk, and think in real life. This helps them answer questions, write stories, or even chat like humans do!

Sometimes, these libraries are public, which means anyone can use them. It's like having a big playground where all the kids can play, no one needs to bring their own toys.

By learning from this huge amount of information, AI models become smarter and more useful, just like how you get better at reading by practicing with lots of stories!
