GPT-OSS 120B tokens per second
Live benchmark data for GPT-OSS 120B on Ollama Pro. Speed, latency, and reliability — benchmarked every ~10 minutes.
What is GPT-OSS 120B?
GPT-OSS 120B is a reasoning model served through the Ollama Pro API. This page tracks its real inference speed — tokens per second, time to first token, and 24-hour reliability — sampled every ~10 minutes on the same fixed prompt and the same measurement method used for every other model, so the numbers are directly comparable across providers. See the full methodology for how each sample is taken.

Reliability
Every benchmark attempt counts here — including timeouts and errors. TPS and TTFT charts above show successful runs only, so you can still see speed data while reliability is red.
Speed is measured as output tokens ÷ generation time. Each benchmark fires one streaming chat completion with a fixed ~300-token prompt, every ~10 minutes. Full methodology →
