What are pretrained language models?

Pretrained language models are like super-smart helpers who have already learned how to understand and talk about many things.

Imagine you have a friend who has read every book in the library. They know all the words, how they fit together, and what they usually mean. That's kind of what a pretrained language model is, it’s a computer helper that has been taught from lots of text, so it can understand and create sentences very well.

These helpers learn by reading a lot of different texts, like stories, articles, and even conversations. The more they read, the better they get at guessing what comes next in a sentence or what a word might mean.

Once they're trained, you can ask them to write stories, answer questions, or even help you with your homework. It's like having that super-smart library friend by your side whenever you need help with words!
