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. Led by Zhang Di (former VP of Kuaishou and technical lead of the Kling video model), it achieved an ELO score of 1388 on Artificial Analysis — ranking #1 through blind community voting.
Unlike traditional AI video generators, HappyHorse 1.0 is a unified multimodal model that generates video and audio together in a single pass — sound effects, background music, and dialogue all synchronized with the visual content.
