Alibaba’s HappyHorse-1.0 Tops AI Video Generation Leaderboard
Alibaba’s HappyHorse-1.0, a new text‑to‑video and image‑to‑video model from the ATH team, claimed the #1 spot on Artificial Analysis’s video arena rankings, matches ByteDance’s Dreamina Seedance 2.0 in Elo score, supports four generation modes, and will open its API around April 30.
On Tuesday evening, the AI evaluation platform Artificial Analysis listed a mysterious video‑generation model codenamed “HappyHorse-1.0” at the top of its leaderboard, sparking widespread discussion in the AI community.
The model surpassed Seedance 2.0 in both text‑to‑video and image‑to‑video categories, pushing Seedance 2.0 to the second position.
Alibaba’s ATH (Alibaba Token Hub) confirmed that HappyHorse‑1.0 is developed by the Zheng Bo team within its newly formed AI core business group. The model is currently in internal testing, and an API is planned for release around April 30.
According to Artificial Analysis, HappyHorse‑1.0 holds the #1 rank in both the “no‑audio” and “with‑audio” leaderboards, with an Elo score almost identical to ByteDance’s Dreamina Seedance 2.0.
The model supports four generation modes—text‑to‑video and image‑to‑video, each with optional native audio—and will be gradually rolled out. The article also outlines Zheng Bo’s background: Alibaba vice‑president, PhD from Tsinghua University, former leader of Google’s display‑ad and map teams (2006‑2017), and later head of algorithm teams at Alibaba’s e‑commerce divisions, focusing on large models, multimodal AI, decision intelligence, deep learning, and search/recommendation systems.
