Core Concepts

What is GPT (Generative Pre-trained Transformer)?

OpenAI's family of language models that power ChatGPT.

Definition

GPT stands for Generative Pre-trained Transformer. It is a series of large language models developed by OpenAI. "Generative" means it creates new content, "Pre-trained" means it learned from a massive dataset before being fine-tuned, and "Transformer" refers to the neural network architecture it uses. GPT-4o is the latest model powering ChatGPT.

💡 Example

ChatGPT uses GPT-4o to generate responses. When you write a prompt, the GPT model processes your input through its transformer layers and generates a response token by token.
