Low cost
The deepest discount. Each request goes to the lowest-cost supply that passes Infer’s checks for the model.

Infer’s lowest open rate for each model next to the lab’s published API price, per 1M tokens. Pulled from the live catalog when this page loads.

List prices are the labs’ published API rates, checked on the date shown in each model’s details. The saving is the smallest one across input, cached input and output on the route shown. Compare every model
Every model ID ends in a route. Cheaper routes draw on a wider pool of qualified supply; stricter routes accept fewer suppliers and cost more. Prices below are for the model selected above.
The deepest discount. Each request goes to the lowest-cost supply that passes Infer’s checks for the model.
Supply has to pass stricter health, capability and privacy checks first. The lowest-cost supply that clears them serves the request.
The strictest checks short of Official. Fewer suppliers qualify, so you pay more for consistency.
The lab’s own API, billed through your Infer wallet at 1.25× the lab’s list price.
Routes change suppliers, never the model family. Supplier identities stay private. How routing works · Current status
Infer speaks the OpenAI Responses and Chat Completions APIs and the Anthropic Messages API. Streaming and tool calls work wherever the model supports them. The samples use the model and route selected above.

You pay the published rate for what you use. There’s no subscription and no top-up fee.
Add $20 or more and spend it on any model and route. When credit runs out, requests stop, so there’s no invoice to surprise you.
Give each app or teammate its own key with daily and monthly caps. Requests already running count toward the cap.
Each completed request lists its model, route, tokens and charge, in your dashboard and in the API response.
Anything else, ask support or read the docs.
Infer sources each model from authorized suppliers and sends every request to the lowest-cost one that passes the route’s checks. Official API is the exception: it uses the lab’s own endpoint at 1.25× list.
Yes. A route can change the supplier, never the model family in your model ID. Supplier identities stay private.
Low cost, for the deepest discount. Move a workload to Balanced or Stable when it needs stricter checks, or to Official API when it needs the lab’s own endpoint. Switching is a one-word change in the model ID.
Infer returns an error before the request runs, and you aren’t charged. Your route and its price never change on their own.
Prepaid. Add $20 or more to your wallet. Each request is charged at the published rate for its model and route, and unused credit stays in your wallet.
Anything that uses the OpenAI Responses or Chat Completions API, or the Anthropic Messages API: the official SDKs, LangChain, the Vercel AI SDK, Pydantic AI, and tools such as Codex, Claude Code and OpenCode.
