Autocomplete, supercharged.
A large language model (LLM) predicts the next piece of text, over and over, very well. Here's how it got that good.
1 · Trained
Read A Huge Library
Learned from vast amounts of text how words, facts and ideas tend to relate. No understanding required, just patterns at enormous scale.
2 · Tuned
Taught To Behave
Further trained with human feedback to follow instructions, stay on task and decline harmful requests.
3 · Prompted
Your Turn
Your prompt plus any context goes in. It predicts the most likely useful reply, one token at a time.
It predicts. It doesn't look up.
