POST /v1/llm/gpt-oss-120b/chat/completions
method-gated
OpenAI-compatible chat completion with gpt-oss-120b (OpenAI's open-weight reasoning model): set the base URL to /v1/llm/gpt-oss-120b in any OpenAI SDK. Up to 32,000 characters in and 2,048 tokens out per call, a fixed price per call, no streaming.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.
