HappyHorse 1.0 vs 1.1: which one renders 480P on Model Studio?

Only HappyHorse 1.1 lists 480P on Alibaba's model list: 480P, 720P and 1080P across its text, image and reference ids. HappyHorse 1.0 starts at 720P. Both take 3 to 15 seconds, and only 1.0 has a video-edit id. HappyHorse is not in the Sume video catalog.

The ids

What this means

• Cheap drafts: choose 1.1, the only one that renders at 480P.
• Editing a clip: 1.0 is the line with a video-edit id on this page; 1.1 lists none.
• Cloudflare's 1.1 page lists 720P and 1080P only, so a 480P request may need Alibaba directly.

On Sume

If a 480p draft is the goal, Sume lists Wan 3.0, Seedance 2.5, MiniMax H3 and Grok Imagine 1.5 at 480p, and Gemini Omni Flash 1.1 at 360p. For editing a clip, the Omni video_url route is documented in the Video Router docs.

Choosing between the two

Pick 1.1 unless you need the 1.0 video-edit id. The only quality claims here are the ones Alibaba's page makes about resolutions and lengths, which this post repeats; I have not compared outputs. If you need a 480P proof, 1.1 is the only one where the page lists the size.

If you only work through Sume, neither version is available, and the closest drafts are Wan 3.0 or Seedance 2.5 at 480p.
