GPT
In plain terms
A family of generative pre-trained transformer language models.
Going deeper
GPT (Generative Pre-trained Transformer) models generate text by predicting the next token, pre-trained on huge corpora then often fine-tuned. They popularized modern generative AI.
Under the hood
Decoder-only transformers scaled across versions; instruction tuning and RLHF align them to user intent.
Examples
ChatGPT, text generation, coding assistants, OpenAI models, chatbots.
Think of it like...
Like an autocomplete grown so capable it can write essays and code.
