- Can I use gpt-oss-20b commercially through EcoHash?
- EcoHash hosts gpt-oss-20b under the model publisher's own licence and does not change its terms, so whether your use is permitted is decided by that licence — read it on the model card at https://huggingface.co/openai/gpt-oss-20b. The EcoHash Terms of Service additionally require you to comply with each model's licence and acceptable-use policy. Your EcoHash bill for API usage is separate from, and does not grant, any right under the model's licence.
