About the Model
What is HappyHorse AI?
HappyHorse 1.0, also known as 快乐马, is a next-generation AI video generator developed by Alibaba's ATH AI Innovation Unit and led by Zhang Di, the former Kuaishou VP and technical lead behind Kling.
The model reached a 1388 ELO score on Artificial Analysis and earned the top ranking through blind community voting, setting a new benchmark for prompt adherence, motion, and cinematic output.
Unlike traditional generators, HappyHorse is built as a unified multimodal model that produces video and audio together, aligning music, sound effects, dialogue, and visual action in one generation pass.
