OpenAI Open Models: Model List and Licenses
About OpenAI
OpenAI is the US AI company known for ChatGPT. Its openai organization on Hugging Face is “the official Hugging Face organization for OpenAI’s open models", hosting the open-weight gpt-oss language models and more.
What It Releases
- gpt-oss (August 2025): according to the model card, gpt-oss-120b (117B total, 5.1B active) is for production, general-purpose, high-reasoning use and fits on a single 80GB GPU (such as an NVIDIA H100 or AMD MI300X). gpt-oss-20b (21B total, 3.6B active) is for lower latency and local or specialized use. Both were trained on OpenAI’s harmony response format, and the model card warns they will not work correctly without the harmony format.
- gpt-oss-safeguard (September 2025): 20b and 120b models for safety classification.
- Whisper for speech recognition: whisper-large-v3 and the faster large-v3-turbo.
- No new models have been released since a research model (circuit-sparsity) in December 2025 (as of 2026-09-26).
Licenses
gpt-oss and gpt-oss-safeguard are Apache-2.0, broadly usable including commercially. Whisper is Apache-2.0 (large-v3) and MIT (large-v3-turbo). Read each model’s license text before use. This summary is not legal advice.
Running Them Locally
- gpt-oss-20b is designed to run locally. Its weights ship in the 4-bit MXFP4 format from the start; because Hugging Face’s parameter count does not match the real one for such weights, the table below leaves it blank.
- There are no official GGUF builds (as of 2026-09-26). For llama.cpp, Ollama and LM Studio, use third-party conversions.
- gpt-oss is also the base of other publishers’ models, such as GPT-OSS-Swallow from the Institute of Science Tokyo.

Recent Models on Hugging Face
The publisher lists 39 models in total on Hugging Face. Below are up to 15 of the most recent generative models (text, image, video, audio and so on), the scope of this site, per organization. Classifiers, feature extractors, research components and repositories without a model card are omitted, and the publisher’s own quantized builds and helper variants are folded into the row of the original model. Parameter counts are left blank for repositories that pack weights into integer types, where Hugging Face’s count is not the real parameter count.
