gpt-oss-120b: what the license allows, and what the maker charges
thecontinuitylayer.com/open-models/gpt-oss-120bOpenAI's open-weight model for reasoning and agentic tasks: 117B total and 5.1B active parameters, released with the smaller gpt-oss-20b in August 2025 under Apache 2.0.
- 1Yes
Is gpt-oss-120b under an open license?
Yes, by OpenAI's own page.
OpenAI's model page states a "Permissive Apache 2.0 license" and adds "Build freely without copyleft restrictions or patent risk."
Yes means: The weights are under an OSI-approved license such as Apache-2.0 or MIT. Partly means the maker's own license with conditions, such as a user cap or an acceptable-use clause; no means research or non-commercial use only.
- 2Yes
Can you download gpt-oss-120b's weights?
Yes, by OpenAI's own page.
Weights for gpt-oss-120b and gpt-oss-20b are on Hugging Face under openai, with MXFP4 quantization of the MoE weights.
Yes means: The maker's page links the weights for download with nothing more than a click-through license. Partly means an access form, an approval step, or only some sizes released.
- 3Yes
Does the maker state gpt-oss-120b's context window?
Yes, by OpenAI's own page.
OpenAI's model page states a 131,072-token context window and 131,072 max output tokens.
Yes means: A token count for the context window is on the maker's page or model card.
- 4Yes
Does the maker say what it takes to run gpt-oss-120b on your own machine?
Yes, by OpenAI's own page.
117B total and 5.1B active parameters; the card says gpt-oss-120b is intended to fit into a single 80GB GPU such as an NVIDIA H100 or AMD MI300X, and gpt-oss-20b runs within 16GB of memory.
Yes means: The page states the parameter count and the memory or hardware it needs. Partly means the parameter count alone.
- 5No
Does the maker publish a price for its hosted gpt-oss-120b?
No, by OpenAI's own page.
OpenAI's model page gives no per-token price for gpt-oss-120b and its rate-limit table shows 0 RPM and 0 TPM for every tier; the page links to Hugging Face for download.
Yes means: A per-token price on the maker's own pricing page. Partly means a hosted version exists but the price sits behind sign-in or a sales call.
- 6Not stated
Does the maker train on your prompts when you use its hosted gpt-oss-120b?
OpenAI's pages do not say.
OpenAI does not serve gpt-oss on its API, so there is no hosted default to grade. OpenAI's API data privacy page (updated 8 January 2026) says of its API platform: "We do not train our models on your data by default."
Yes means: Here no is the good answer: the maker's page says what you send its API is not used for training. Yes means it is unless you opt out; partly means it depends on the plan or the page does not give the default.
- 7Yes
Can you fine-tune gpt-oss-120b and keep the result?
Yes, by OpenAI's own page.
Apache 2.0 with no added condition; the card says "Both gpt-oss models can be fine-tuned for a variety of specialized use cases" and lists the models as fine-tunable.
Yes means: The license allows fine-tuning and the fine-tuned weights are yours to keep and share. Partly means conditions follow the derivative, or a hosted fine-tune you cannot download.
License as stated: Apache 2.0, stated on the model card and on OpenAI's model page.. Every grade above is read from OpenAI's own page on the day shown. If a page has changed, tell us.
