April 8, 2026 - The global AI video generation industry was shaken today as open-source model HappyHorse-1.0 rocketed to the very top of Artificial Analysis Video Arena, the world's most authoritative blind-test leaderboard.
In the Text-to-Video (no audio) category, HappyHorse-1.0 achieved 1333-1357 Elo points, surpassing the previously dominant ByteDance Seedance 2.0 by nearly 60 points. It also set a new all-time record in the Image-to-Video category with 1391-1406 Elo and secured second place in the demanding audio-inclusive track.
Completely open-source with full commercial licensing, HappyHorse-1.0 features a 15-billion-parameter unified single-stream Transformer architecture that natively generates synchronized audio and video in one pass.
Key capabilities include:
* 8-step denoising inference (no CFG required)
* Native lip-sync across 7 languages (Mandarin, Cantonese, English, Japanese, Korean, German, French)
* 1080p cinematic output in just 38 seconds on a single H100 GPU
* Full model weights, distilled versions, super-resolution module, and inference code released on GitHub
The model was developed by the independent team formerly operating under Alibaba's Taotian Group Future Life Laboratory (ATH-AI Innovation Division), led by Zhang Di - former Vice President of Kuaishou and technical architect of Kling AI.
"HappyHorse-1.0 proves that true innovation in AI video no longer requires closed-source walls," said the development team. "By focusing on real user preference rather than benchmark hype, we have built the new standard for accessible, high-performance video generation."
The complete model is now publicly available.
