KuaishouSeedRouter 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.
VideoGrok Imagine Video 1.5 turns a prompt or one image into a 6–15 second clip with sound at 480p or 720p. Pay per second, no plan, failed runs are free.
Get startedCheck the models SeedRouter supports, what each one can do and what it costs before you write a line. No mystery wrapping and no surprise behaviour: every model has a documented interface.
/02Switch model families as your needs change. Move between GPT, Claude and Gemini, or between image and video families, without rewriting your stack. SeedRouter keeps the request shape the same.
/03It starts from model pages and API paths, not demos. Every entry point is designed for an integration that ships and stays up.
Browse the video, image, language and audio models on SeedRouter, and compare them by the capabilities and controls a production workflow needs.
Generate and edit video from text or a first frame, at the resolutions and durations each model supports, with native audio where the model provides it. You get a task id you can poll or receive by webhook.
Explore all video APIsCreate images from text or edit them with natural-language instructions and reference images. Text rendering, consistent characters and product shots are all available on SeedRouter with one request shape.
Explore all image APIsBuild chat, reasoning, code generation and agent workflows with tool calls and structured output. Language models on SeedRouter are served through an OpenAI-compatible endpoint, so existing SDKs work by changing the base URL.
Explore all LLM APIsGenerate full songs, voices and dialogue from a prompt, or separate stems from an existing track. SeedRouter delivers audio as tracks with duration, lyrics and cover art where the model provides them.
Explore all audio APIsChoose a workflow for the output you need. Explore its inputs, quality checks and implementation options.
Turn product references into reviewable campaign variants, with checks for product fidelity and revision costs.
Connect scripts, character references and reusable shots for serialized visual storytelling.
Build a shot-based workflow with clear acceptance criteria, selective revisions and a delivery budget.
Create reviewable product copy and campaign drafts from approved product and business information.
Extract invoice fields and line items, then validate quantities, totals and source evidence.
Build answers around retrieved passages, technical terminology and traceable document sources.
Predictable behaviour, clear pricing and real-time control. What SeedRouter gives you out of the box.
Once
is how often you pay per request
SeedRouter bills you when the result is delivered. A failed request costs nothing, and you can retry or switch models with the same key.

Video and long image jobs return a task id. Poll it or get a webhook when the output is ready.

Everything you need to know before building on 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.
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.
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.
Yes. Language models are served through an OpenAI-compatible endpoint. Point the SDK at SeedRouter, use your SeedRouter key and keep your existing code.
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.
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.
No. Top up a balance in USD and spend it across every model on SeedRouter. Unused balance stays in your account.
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.
