O3 Mini API
O3 Mini is a language model from openai, available on Routeriva under the model ID o3-mini-2025-01-31. You call it with the same sk- key you use for every other model — no separate openai account is needed.
On Routeriva it costs $0.33 per 1M input tokens and $1.32 per 1M output tokens, compared with the official list price of $1.10 / $4.40 — about 70% less. Prices shown are the lowest across the routes that serve this model; your key is charged at its own route's price.
O3 Mini works with the official OpenAI SDKs on both /v1/chat/completions and /v1/responses, including streaming and tool calls, so Codex, Cursor and other OpenAI-based tools work by changing the base URL.
