gpt-oss
Two open OpenAI models, gpt-oss-120b and gpt-oss-20b, plus reference run implementations including Metal for Mac. A rare case of OpenAI releasing weights.
Who it is for
For people who want to try an OpenAI open model themselves or study the Harmony format.
How to start
- Easiest run:
ollama pull gpt-oss:20b, thenollama run gpt-oss:20b. - For a server:
vllm serve openai/gpt-oss-20b. - For the repo's reference tools:

The core library for working with models: one codebase for text, vision, audio and multimodal tasks, for both inference and training. Most new open models ship through it.
A self-hosted ChatGPT-style interface that connects to Ollama and any OpenAI-compatible API. Installs with a single Docker command and runs on your own server.
A C/C++ engine that runs language models on ordinary hardware: laptops, phones, GPU-less servers. Much of local AI, Ollama included, is built on it.
Repository of the large open DeepSeek-V3 mixture-of-experts model: description, benchmark results and run instructions. It showed an open model can stand next to closed ones.
The foundation under most modern neural networks: GPU-accelerated tensors and automatic differentiation, wrapped in ordinary Python. Transformers, Llama and nearly every open model are written on it.
