FAQ
About Wan 2.2 Fast API
Wan 2.2 Fast exposes the same modes and controls as Wan 2.2 in the playground but bills under the Flash model name and targets faster turnaround.
Parameter list matches non-fast Wan 2.2 here, including optional 720p in image-to-video. Choose Fast when your account routes this model id for speed or cost.
720p appears in the resolution list for image-to-video. Text-to-video uses 480p or 1080p in the current playground.
