HappyHorse 1.0
HappyHorse 1.0 is an AI video model from Alibaba's ATH innovation unit that topped blind-test leaderboards for both text-to-video and image-to-video in early 2026. A single 15B-parameter transformer generates 1080p clips with joint audio and lip-sync across seven languages. It is positioned as a budget challenger to ByteDance's Seedance 2, available through platforms like fal, Atlas Cloud and Replicate rather than a first-party app.

Our take
HappyHorse climbed to #1 on blind text-to-video and image-to-video rankings while costing less than Seedance 2, with native audio and seven-language lip-sync in one pass. The catch: it is an Alibaba model still under development, used through third-party platforms like fal and Replicate rather than a polished first-party app. Strong value if you are comfortable working via API.
Best for
Creators and developers who want top-tier 1080p video with built-in audio and lip-sync at a lower price, and don't mind generating through API platforms like fal or Replicate.
Pros
- Topped blind leaderboards for text-to-video and image-to-video in 2026
- Joint audio-and-video generation with lip-sync in seven languages
- 1080p output at a noticeably lower price than rival frontier models
- Accepts both text and image prompts in a single 15B-parameter model
Cons
- No first-party app - you use it through fal, Atlas Cloud or Replicate
- Still described as under development, so behaviour may shift
- Pricing varies by whichever host platform you run it on
How it compares
Against Seedance 2 and Kling 3.0, HappyHorse trades a little polish for price and topped the same leaderboards; unlike first-party tools, it has no consumer app of its own and lives on third-party model platforms.

fal
fal is a serverless platform for running generative media models - image, video, audio and 3D - behind one fast API.
