02 Why SeedRouter.

Model access should be clear before you integrate.

SeedRouter is not a bargain aggregator and not a model showroom. It is the platform layer that makes adding an AI model to a real product a considered choice, not a guess.

FAQs

Common questions

Everything you need to know before building on SeedRouter.

What is SeedRouter?

SeedRouter is one API in front of image, video, language and audio models. You create one key, load a balance and call any model with the same request shape and the same billing. It replaces separate accounts, keys and invoices for each model vendor with a single integration.

How does SeedRouter pricing work?

Every model on SeedRouter has a listed price: per request, per image, per second of video or per token. You are charged when the output is delivered and nothing for failed requests. There is no subscription and no monthly minimum.

What happens when a model is unavailable?

The request returns an error instead of a result, and you are not charged for it. Retry when the model is back, or send the same request to another model on SeedRouter with the same key and the same request shape.

Can I keep using the OpenAI SDK with SeedRouter?

Yes. Language models are served through an OpenAI-compatible endpoint. Point the SDK at SeedRouter, use your SeedRouter key and keep your existing code.

How do video and other long-running jobs work on SeedRouter?

Video and some image and audio models run as tasks. The request returns a task id; poll it or register a webhook, and the output arrives as a CDN link when it is ready.

Which models does SeedRouter support?

Image, video, language and audio families, including GPT, Claude, Gemini and GPT Image, plus video and image families such as Seedance, Flux and Qwen Image. The full list with prices is on the models page, and it grows without changes on your side.

Do I need a subscription to use SeedRouter?

No. Top up a balance in USD and spend it across every model on SeedRouter. Unused balance stays in your account.

Is SeedRouter suitable for production traffic?

Yes. SeedRouter is built for products, not demos: per-request billing you can audit, webhooks for long jobs, and no charge for requests that fail.
