Frequently asked questions
Can Wan 3.0 Prime animate a still image?
Yes. Pass a first_frame URL in the request body and Prime animates from that opening shot. Pass first_frame and last_frame together to define both opening and closing shots.

Up to 10 reference images at 20 MB each, the highest reference image budget in the routed video catalog on OneInfer.
Where is the canonical Wan 3.0 Prime page on OneInfer?
The canonical model page with current pricing, providers, and capabilities is /models/alibaba/wan-3.0-prime. This page is a focused facet of that entity, not a replacement for it.
How should I treat benchmark or price claims on Prime?
Check each claim's provenance label and observed date. Vendor-reported, independently verified and derived numbers are shown as separate evidence classes on this hub.
