Alibaba: HappyHorse 1.1 · fastrouter

HappyHorse 1.1 is Alibaba's closed-weight cinematic video generation model, producing clips of 3-15 seconds with synchronized audio and multilingual lip-synced dialogue generated in a single pass. It generates video from a text prompt, a single starting image, or a set of reference images, and supports video editing of existing clips, at output resolutions of 480p, 720p, and 1080p. It improves on HappyHorse 1.0 with stronger prompt adherence, smoother motion, and more consistent characters across frames, and previously topped the Artificial Analysis video arena anonymously before Alibaba was revealed as its maker.
