ComfyUI lists Comfy, Runware, Wavespeed, Fal and Higgsfield as launch providers, with multiple providers available where the model supports it. It says developers can queue jobs and collect results as they finish, while the queue retries rate-limit and transient errors. ComfyUI also says inputs and outputs are retained for 24 hours, then deleted. Payment uses Comfy credits, with no subscription or Router fee, according to the announcement.
