The big idea
AI did not go to school. Nobody taught it like a teacher teaches kids. Instead, the people who built it showed it MILLIONS of pages from books, websites, and articles. Then it learned the patterns of how words go together.
Some examples
- After reading lots of weather reports, AI knows that 'sunny and' is often followed by 'warm'.
- After reading lots of fairy tales, AI knows that they often start with 'Once upon a time'.
- After reading lots of recipes, AI knows that flour and sugar usually go together.
- After reading lots of conversations, AI knows how to take turns.
Try it!
Ask a chatbot: "Finish this sentence: My favorite ice cream flavor is" See how it tries to guess. It does not know YOUR favorite — it is guessing what most people would say.

AI Knows About Words, Not About Truth
