How do current large language models generate text?

Large language models are like super-smart text robots that can write stories, answer questions, and even chat with you.

Imagine you have a giant box full of sentences, every sentence is like a piece of puzzle. When the robot wants to generate new text, it picks the best next piece from the box based on what came before. It keeps doing this, one sentence at a time, until it has written something new and complete.

How They Learn

These robots aren't born smart, they learn by reading a lot of books, articles, and websites. The more they read, the better they get at guessing which words or sentences should come next. It's like learning to speak a language by listening to people talk all day long.

How They Write

Once they're trained, they can write new text on their own. If you ask them to write a story about a cat, they start with something simple, maybe “The cat sat on the mat.” Then they look at that sentence and pick the next one from their giant box of sentences. They keep going until the story feels just right.

It’s like having a really good friend who knows all the best words to use in every situation!
