HappyHorse 1.0 Complete Analysis: How a Chinese AI Video Model Took the #1 Spot
An in-depth analysis of HappyHorse 1.0's technical capabilities behind its Artificial Analysis rankings, including ELO score comparisons, model architecture, and how to get started.
A dark horse has emerged in the AI video generation space.
HappyHorse 1.0, a video generation model, quietly topped the leaderboard on Artificial Analysis’s Video Arena, surpassing ByteDance’s Seedance 2.0 and Kuaishou’s Kling 3.0. The AI community was excited — after all, ranking #1 on this platform isn’t about luck.
The Numbers First: How Did It Perform on Benchmarks?
Data speaks louder than opinions.
Artificial Analysis is a platform that relies on real human blind voting. Users compare two videos without knowing which model generated each, then pick their preference. With large sample sizes, the results are highly reliable.
As of April 2026, HappyHorse 1.0’s performance across four categories:
| Category | Ranking | ELO Score |
|---|---|---|
| Text-to-Video (No Audio) | #1 | 1360 |
| Text-to-Video (With Audio) | #2 | 1217 |
| Image-to-Video (No Audio) | #1 | 1403 |
| Image-to-Video (With Audio) | #1 | 1159 |
