Happy Horse 1.0 eliminates the need for separate audio post-production. By processing video and audio tokens within the same unified Transformer sequence, the model ensures that the sound of a splashing wave or a roaring engine perfectly matches the on-screen action.
| Start Frame | End Frame | Prompt | Output Video |
|---|---|---|---|
 |  | A cinematic shot of a heavy thunderstorm hitting a futuristic neon city. The sound of thunderclaps and rain hitting metallic surfaces is perfectly synced with the flashes of lightning. |
With an Elo score of 1480, Happy Horse 1.0 is the world's most powerful tool for bringing static images to life. It maintains extreme character consistency and environmental detail, making it ideal for animating concept art, portraits, and product photos.
One of the biggest pain points in AI video is unnatural movement. Happy Horse 1.0 solves this with a highly optimized motion engine that understands real-world physics, ensuring that human gaits, fluid dynamics, and camera pans are smooth and stable.
| Prompt | Output Video |
|---|---|
| A high-speed F1 car drifting around a sharp corner on a wet track. Water sprays realistically from the tires, and the camera follows the drift with a professional cinematic pan. |
Happy Horse 1.0 is a native multi-modal model that understands the nuances of different languages. Users can input complex, culturally specific descriptions in their native tongue to achieve highly accurate visual representations without losing detail in translation.
| Prompt | Output Video |
|---|---|
| (Chinese Prompt) 一位身着汉服的少女在盛开的梨花树下漫步，花瓣随风飘落，阳光穿过树叶洒在她身上，意境唯美动人。 |
Happy Horse 1.0 breaks the speed barrier by reducing the denoising process to just 8 steps without sacrificing visual clarity. A highly efficient Transformer and optimized sampling deliver roughly 1.2x end-to-end acceleration, so creators can iterate and generate professional-grade Happy Horse videos significantly faster than with traditional models.
Happy Horse 1.0 integrates advanced lip-sync capabilities, ensuring that generated dialogue perfectly matches the on-screen character's mouth movements with ultra-low WER (Word Error Rate). This removes manual post-production adjustments, making character animation more realistic and efficient.
As an open-weight model, Happy Horse 1.0 is democratizing access to elite AI video. Widely recognized as a potential Seedance 2.0 killer, Happy Horse disrupts the dominance of proprietary models by giving developers and creators unprecedented performance. This open-source advantage is accelerating global innovation and proving that community-accessible tools can outrank closed ecosystems on benchmark battlegrounds.

Alibaba's #1-ranked AI video model, explained
Happy Horse is Alibaba's new AI video generation model that topped the Artificial Analysis Video Arena in April 2026 for both text-to-video and image-to-video. A single prompt renders cinematic footage with synchronized dialogue, sound effects, and physics-grounded motion — no audio editor, no manual lip-sync pass. The official Happy Horse API is marked coming soon, so gptimg pairs this preview page with Seedance 2.0, the closest production-ready alternative ranked #2 on the same leaderboard, letting you generate Happy Horse-class clips today.
Happy Horse generates video and matching sound effects from one prompt. Dialogue, ambient tone, and Foley render alongside the picture in a single pass.
Ranked #1 globally for text-to-video and image-to-video. Happy Horse delivers cinematic, photo-realistic frames that hold up at 1080p.
Happy Horse solves the AI-video warp problem with a motion engine tuned to real physics. Gaits, fluids, and camera pans stay smooth.
Happy Horse reads English, Chinese, Japanese, Korean, German, and French natively. No prompt-translation step before you render.
Happy Horse gets professional output in just 8 denoising steps. Iteration lands about 1.2x faster end-to-end than traditional video models.
Happy Horse lands ultra-low word-error-rate lip-sync. Dialogue matches mouth movement without a manual post-production pass.
Full video clips with sound in seconds, not hours
