What Does GPT Stand For?

GPT stands for Generative Pre-trained Transformer, a type of large language model. “Generative” means it produces text, “pre-trained” means it first learns from a very large body of text before being adapted to tasks, and “transformer” refers to the neural network architecture it is built on.

How GPT Models Work

They generate text one token at a time by predicting the most likely next token, given the prompt and the text generated so far.

A Family of Models

The term is used for a series of language models and also, informally, for chat assistants built on them.
