Alibaba updated HappyHorse, the video model it quietly floated to the top of an arena leaderboard earlier this year before claiming it. Version 1.1's image-to-video build now shows up on Model Studio, with the company citing better skin texture, steadier character identity across clips, and tighter audio-visual sync. The usual upgrade copy, in other words.
Four modes carry over: text-to-video, image-to-video, reference-to-video with up to nine reference images, and video editing. Prompts run to 2,500 characters, output tops out at 1080p, and clips land between 3 and 15 seconds. The reference-to-video mode and multi-shot consistency are the parts that matter, since keeping a character stable across cuts is where most rivals still wobble.
Native lip-sync covers seven languages on the 1.0 line. Whether 1.1 shifts that list, Alibaba doesn't say.
Pricing is the soft spot. Alibaba's enterprise channel billed 1.0 text-to-video at roughly 22 cents per second for 1080p, while third-party resellers range from 16 to 32 cents. The original Russian post pegged the rate at 14 cents in HD and 18 cents at 1080p, plus a 40 percent launch discount, none of which lines up with published provider rates. A 1.1 text-to-video endpoint is already live on reseller Atlas Cloud. Direct access through Alibaba's own channels for the previous version stayed in closed beta and region-locked, so whether you can reach 1.1 from outside China is the real open question.
Bottom Line
HappyHorse 1.1's image-to-video build is live on Alibaba Cloud Model Studio, supporting 2,500-character prompts, 1080p output, and four generation modes including nine-image reference-to-video.
