What Is Happy Horse 1.1? Alibaba's Open AI Video Model
Happy Horse 1.1 is the upgraded release of Alibaba's open Happy Horse AI video model. It keeps the open-weight, multi-shot foundation of Happy Horse 1.0 while adding native synced audio, smoother and more expressive motion, and stronger multi-character consistency — a clear step up for anyone who wants cinematic AI video from a single prompt or image.
The headline upgrade in Happy Horse 1.1 is reference control. The model accepts up to 9 reference images, and each reference can carry its own dialogue and storyboard timing. Audio runs through the same Transformer as the video, so speech, sound effects, and music land already synced to the picture in one render pass — no separate lip-sync step.
Happy Horse 1.1 supports text-to-video, image-to-video, and reference-to-video at 720p and 1080p, with clips from 3 to 15 seconds. Thanks to long-context semantic preservation and segment-based scene planning, it handles longer, more complex prompts while keeping characters, wardrobe, and style coherent across every shot.
