Wan 3.0 at 720p by clip length: 2 to 30 seconds on Sume

Wan 3.0 on Sume takes clips of 2 to 30 seconds and bills $0.125 per output second at 720p, so a 2-second clip is $0.25, 10 seconds is $1.25 and the 30-second maximum is $3.75.

Source of the limits and rates

The 2 to 30 second range is in the Video Router docs; prices come from the catalog and the rate card. The estimator scales linearly with duration across the 2 to 30 second range.

Veo comparison

Google lists Veo 3.1 Lite at $0.05 per second at 720p on its Gemini API pricing page, so 10 seconds lists at $0.50 against $1.25 here; Veo is not a Sume model.
