ComfyUI launches Comfy Router for image, video, 3D, and audio models

ComfyUI has launched Comfy Router, one API for image, video, 3D, and audio models. Calls use the same model string and arguments, without a new SDK, a new key, or a redeploy.

The caller names the provider, and Comfy Router calls only that provider. If the provider is down, the request fails there, with no silent fallback, and every job returns the provider that ran it. submit() returns a request ID immediately; the queue retries 429 responses and transient errors until a slot opens, and subscribe() submits a job and polls until it finishes. A few hundred jobs can be queued by ID and collected as they complete, without blocking on a five-minute video render.

Inputs and outputs are retained for 24 hours and then deleted. Usage is billed with Comfy credits, with no subscription and no Router fee. Providers at launch are Comfy, Runware, Wavespeed, Fal, and Higgsfield, including more than one provider where a model supports it.
