Happy Horse 1.0 AI Video Generator
Create Cinematic AI Videos with Unmatched Motion Quality Using Happy Horse 1.0
Happy Horse 1.0 is the world's #1 ranked AI video generator on the Artificial Analysis Arena. Built by Alibaba's ATH AI Innovation Unit on a 40-layer, 15B self-attention Transformer, it jointly generates video and audio from text or images with state-of-the-art motion quality, prompt obedience, and character continuity. Supporting 7 languages natively, Happy Horse delivers cinematic 1080p results at record speeds.
Happy Horse 1.0, launched on April 26, 2026 by Alibaba's ATH AI Innovation Unit, claimed the top spot on the Artificial Analysis Arena leaderboard with an Elo rating of 1381 on the visual track and 1238 with audio, surpassing models from OpenAI, Google, and ByteDance in blind human preference evaluations for motion quality and visual coherence. The model is built on a 40-layer, 15-billion parameter self-attention Transformer that generates video and audio jointly in a single pass, avoiding the multi-stream complexity found in competing approaches.
The model supports seven languages natively for lip-sync — English, Mandarin, Cantonese, Japanese, Korean, German, and French. Beyond text-to-video, it offers image-to-video for animating a single first frame, plus reference-to-video that accepts up to nine reference images to lock multi-character consistency across shots. Output resolutions include 480p, 720p, and native 1080p across five aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4), with video durations ranging from 3 to 15 seconds.
Happy Horse 1.0 distinguishes itself from competitors through its cinema-grade motion fidelity. Where other models produce floaty or physics-breaking movement, Happy Horse maintains consistent gravity, momentum, and collision behavior. The unified audio generation produces synchronized dialogue, ambient sound, and Foley effects in a single forward pass, eliminating misalignment issues. Alibaba has also announced open-source releases of the base model, distilled model, super-resolution module, and inference code. On LoveGen AI, users can compare Happy Horse outputs directly with Sora 2, Veo 3.1, and other models to find the best result for each project.
