HappyHorse vs Kling vs Seedance: New #1 AI Video Model (2026)

An anonymous model called HappyHorse appeared on the Artificial Analysis Video Arena in early April 2026 and beat everything — Kling, Seedance, Runway, all of them. Then Alibaba confirmed it was theirs. The AI video leaderboard reshuffled overnight.

Here's what happened, how these models compare, and how you can use Kling and Seedance engines on ZenCreator right now.

Quick answer: what does this mean for creators?

Benchmarks shift every few months — HappyHorse is #1 today, something else will be tomorrow. What matters is having access to the best engines inside a workflow that actually ships content. ZenCreator gives you 16 video models — including Kling and Seedance families — with face consistency, lip sync, and social export. No standalone benchmark winner offers that.

What is HappyHorse and why does it matter?

Alibaba's ATH division submitted HappyHorse anonymously to the Artificial Analysis Video Arena — the most widely-used blind benchmark for AI video. Human raters scored it #1 on both text-to-video and image-to-video without knowing which model they were judging^[1].

The team includes researchers from Tongyi Lab and Taotian Technology. Bloomberg, CNBC, and South China Morning Post all covered the reveal^[2].

Key specs: 15B-parameter unified Transformer, 1080p, 3–15 second clips, joint audio-video generation, 7-language lip-sync. API launched April 27 via Alibaba Cloud^[6].

The catch: HappyHorse is a standalone API. No pipeline tools, no face swap, no social export, no character consistency. You generate one clip — that's it.

How the benchmark leaderboard looks now (April 2026)

Rank	Model	Elo (T2V)	Elo (I2V)	Developer
#1	HappyHorse	1,366	1,401	Alibaba ATH
#2	Seedance	1,270	1,347	ByteDance
#3	Kling	1,246	—	Kuaishou

This leaderboard changes every few months. Runway Gen-4.5 was #1 in December. Kling and Seedance passed it in February. Now HappyHorse leads. By the time you read this, it may have shifted again.
