Happy Horse 1.1 is Alibaba's flagship video model, and it currently sits at the top of the Artificial Analysis Video Arena, ranked first by blind human preference across head-to-head comparisons with every other major model. The architecture is unusual: a single 40-layer self-attention Transformer that generates pixels and audio waveforms in the same pass, with no cross-attention modules and no separate audio decoder. The training data and the inference pipeline both treat audio and video as one signal, which is a big part of why its lip-sync and motion feel so natural.
The standout capability is multilingual lipsync. Where most models that handle dialogue are calibrated to English, Happy Horse generates accurate mouth shapes for English, Mandarin, Cantonese, Japanese, Korean, German, and French. This unlocks dialogue-driven content for the world's largest video-consuming markets without leaving the platform. Combined with ambient sound, music, and effects all rendered in the same pass, it produces shot-ready dialogue scenes that previously required separate audio production.
Three endpoints share the same engine. Text-to-video for original concepts. Image-to-video to animate a still. Reference-to-video accepts up to nine reference images so you can lock character appearance, location, and key props across multi-shot sequences. Duration runs 3-15 seconds at 720p or 1080p, with five aspect ratios on offer — full landscape, portrait, square, and the two close 4:3 variants. One prompt cap at 2,500 characters means you can direct shots in detail.
