HappyHorse 1.1 AI Video Generation

HappyHorse 1.1 is the newer of Alibaba's two HappyHorse video models on FlyAIgh. Against the original 1.0 it renders sharper frames, smoother motion and a steadier character from shot to shot — and during its launch it is also the cheaper of the two.

The quirk both versions share is that you do not pick a mode. Give HappyHorse no image and it generates from your text; give it one image and it animates that frame; give it two to nine images and it treats them as references and composes them into one shot. That makes it handy while you are still deciding whether a shot needs references at all — the same prompt box covers all three cases.

Clips run any whole number of seconds from 3 to 15 in 16:9, 9:16, 1:1, 4:3 or 3:4, at 1080p by default or 720p. Nine reference images per generation is a generous budget: the same as Seedance 2.0 and more than Kling V3 Omni's seven.

HappyHorse 1.1 is on a limited-time 40% launch discount: 6.6 credits per second at 1080p instead of the 11-credit list rate. That is 33 credits for 5 seconds, 66 for 10 and 99 for 15. 720p costs three quarters of that — 25 credits for 5 seconds, 50 for 10 and 74 for 15. When the promotion ends the price returns to the list rate; the generator always shows the current total before you start.

HappyHorse is strongest on stylised work — illustration, anime-adjacent looks, advertising aesthetics — and on shots assembled from several references. It is weaker than VEO 3.1 Quality on photorealistic texture and weaker than Hailuo 2.3 on precise camera direction.

HappyHorse 1.0 stays available on its own page for anyone matching footage already made with it; for new work, 1.1 is the better and currently cheaper pick. Like every model on FlyAIgh, it runs on one credit wallet, with no Alibaba Cloud account, Bailian API key or Mainland China registration.
