GPT
Also known as: GPT (OpenAI) · GPT-4 · GPT models
GPT (Generative Pre-trained Transformer) is OpenAI’s family of LLMs — the models behind ChatGPT.
- Versions have evolved: GPT-3 → GPT-4 → the o-series reasoning models.
- “GPT” has become a generic label for chat-style LLMs in common speech.
- Available via API (cloud) or in apps.
Don't conflate: GPT is one company's model family. LLM is the *category*. There are many excellent non-GPT LLMs — Claude, Gemini, Llama, Mistral, Qwen — all of them LLMs.
