by Tongyi · Happy Horse 1.1 (Wan family) text-to-video (asynchronous task): 3-15 seconds, 720P / 1080P, 16:9 / 9:16 / 1:1 / 4:3 / 3:4 / 4:5 / 5:4 / 21:9 / 9:21. With a first-frame image it becomes image-to-video automatically (same price). Smoother motion, steadier subjects and more realistic texture than 1.0.

Models like this bill for real per image / per second / per call and are mostly async tasks, so there is no one-click test here. Use the sample code above, or generate in the matching workbench (which has a parameter panel and a cost estimate).
