What Is Happy Horse 1.0
Happy Horse 1.0 isn't just another text-to-video model. It's a 15-billion-parameter creative engine that topped the Artificial Analysis Video Arena by prioritizing what creators actually care about: consistent motion, realistic physics, and the rare ability to generate synchronized audio without a separate pipeline. It uses a unified 40-layer single-stream self-attention architecture to handle video and sound as one.
One Model, Full Audiovisual Output
No more stitching audio tracks or fighting with cross-attention modules. Our single-stream architecture treats text, image, video, and audio as a unified sequence, generating perfectly synchronized dialogue, ambient sound, and foley in a single pass.
Consistency That Holds Up Under Pressure
Built for complex, multi-layered scenes. With an Elo of 1,375 (T2V) and 1,392 (I2V) on the Artificial Analysis Arena, it consistently outperforms Seedance 2.0 and others in blind tests, especially in physically grounded action and complex camera movements.
Open Source Future
We believe the best AI tools should be in the hands of everyone. The development team has committed to fully open-sourcing Happy Horse 1.0—including the base model, distilled versions, and inference code—by mid-2026.
