SeedRouter puts image, video and language models behind a single key. Send one request, get the result, pay only for what was delivered. A request that fails costs nothing.
SeedRouter bills you when the result is delivered. A failed request costs nothing, and you can retry or switch models with the same key.
Check 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.
Switch 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.
Create 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.
Generate 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.
Track usage and see cost per request as it happens, across every model.
SeedRouter is one API in front of image, video, language and audio models.
Build 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.
Video and long image jobs return a task id. Poll it or get a webhook when the output is ready.
