1What the notes say

HappyHorse appears only in Alibaba Cloud Model Studio's list of newly released models, which does not say who trains it; the register records it as listed there. Version 1.0 arrived over four days in April 2026 as text-to-video, image-to-video, a reference-to-video model that takes up to nine images and a video edit model. Version 1.1 followed on 16 June 2026 with notes on shot control, steadier subjects and consistency across clips.
