GPT
Also: Generative Pre-trained Transformer
Short for “generative pre-trained transformer” – a family of language models from OpenAI.
The name describes the design: a generative model that has been pre-trained and is based on the transformer architecture. The GPT models are the basis of ChatGPT.
In everyday language, “GPT” is sometimes used as a synonym for language models in general. Strictly speaking, though, it is one provider’s model name; other providers have their own model families.
