A page is about 600 tokens in and 60 out, a support reply 200 in and 300 out, an email 150 in and 250 out. Nothing else is counted: no cache discount, no batch rate, no free tier.

OpenAI publishes the weights, so you can run gpt-oss-20b on a server you rent by the month. It needs about 14 GB of RAM on a CPU, and the cheapest plan we track with that much and a disk included is OVHcloud VPS-4 2027 at $27.11/mo, streaming an estimated 4.4–8.7 tok/s.

Every provider selling gpt-oss-20b

Four groups, decided by the price and by what the provider publishes about it. Prices are per million tokens, and the share is that row against OpenRouter's price. OpenAI trained gpt-oss-20b and sells it on no catalog we read, so the price every row is measured against is OpenRouter's.
