HappyHorse-1.0 is a top-tier open-source AI video generation model heavily backed by Alibaba Taotian Group, boasting an astonishing 15 billion (15B) parameters. As a unified Transformer model, it breaks down traditional barriers, capable of directly generating cinematic 1080p video alongside perfectly synchronized audio from text or image prompts.
HappyHorse-1.0 natively supports six major languages: Chinese, English, Japanese, Korean, German, and French. Not only does it deliver highly expressive facial micro-expressions and incredibly natural body movements, but it also achieves ultra-precise multilingual lip-sync. It generates synchronized dialogue, ambient sound, and Foley simultaneously with the video frames, completely eliminating the need for tedious post-production dubbing. Thanks to extreme algorithmic optimization, the model requires no classifier-free guidance (CFG), maintaining top-tier visual quality in just 8 denoising steps at record-breaking speeds. Currently, HappyHorse-1.0 firmly holds the number one spot on the authoritative Artificial Analysis Text-to-Video Arena with a towering Elo score of 1333.

Happy Horse 1.0 is Alibaba's latest cutting-edge AI video generation model. It redefines video creation by using a 15B-parameter unified 40-layer single-stream Transformer architecture. It supports both Text-to-Video (T2V) and Image-to-Video (I2V) workflows, featuring native joint audio-video synthesis. This means it can generate high-definition video and synchronized audio simultaneously without relying on external tools.
Its biggest strength is cinematic multi-shot storytelling and unified multimodal control. You can use it to create highly realistic 1080p clips with seamless scene transitions, natural human-centric motion, and precise lip-sync supporting 7 languages. It also demonstrates incredibly strong prompt adherence, accurately capturing complex scene directions without hallucinating unrequested elements.
WeryAI offers free daily starter credits for new users, so you can try the powerful Happy Horse 1.0 model at no cost. If you need frequent batch generation, professional cinematic production, or extended clip lengths, there are also flexible subscription plans available.
Happy Horse 1.0 delivers stunning native 1080p HD resolution with a 99.5% success rate. Thanks to its advanced DMD-2 distillation technology, the model requires only 8 denoising steps[2][4]. As a result, inference is blazingly fast—it can output a 1080p video with synced audio in approximately 38 seconds, drastically reducing waiting times compared to traditional video models.
With its highly consistent visuals and built-in audio capability, it is ideal for creating product demonstrations, social media shorts, cinematic trailers, concept videos, and e-commerce marketing assets[1][3][9]. It perfectly serves creators, marketers, and designers who need to turn text or images into polished, production-ready video assets without breaking their workflow.
Happy Horse 1.0 stands out by replacing the traditional "two-stream" approach with a unified single-stream Transformer, meaning video and audio are jointly synthesized in one pass for perfect synchronization. Furthermore, it recently topped the Artificial Analysis AI Video Arena, defeating top closed-source models like Seedance 2.0 and Kling 3.0 in Elo ratings. It remains the absolute only open-source model to currently dominate both text-to-video and image-to-video global leaderboards.
