The Giant Study Pile

To teach an AI, you need a huge pile of examples. Not hundreds. Not thousands. We are talking about billions of words, pictures, and sounds.

So where do people get all that? Mostly from the internet. Big AI companies scoop up websites, books, videos, and conversations to use as study material.

Common sources

Websites and blogs
Books that are free to read
Wikipedia, the online encyclopedia
Public videos and their captions
News articles and magazines

Why this can be tricky

Sometimes the study pile includes things people did not mean to share with an AI. Maybe a person wrote a poem online for fun, and the AI used it as practice without asking. Many grownups think that is unfair, and they are still figuring out the rules.

An AI knows what it has read. If it has never read something, it does not really know it.
— A helpful teacher

Bad examples make bad AI

If the pile has mean messages, the AI might pick up mean habits
If the pile is mostly in English, the AI will be worse at other languages
If the pile is old, the AI may not know about recent events

The big idea: AI only knows what it has studied. The study pile is huge, but it is not perfect, and people are still working out the fairest way to build it.
