Happy Horse 1.0 is a state-of-the-art, open-source AI video generator designed to transform text and image prompts into stunning, high-definition videos. By utilizing a 15B-parameter unified Transformer architecture, it enables seamless joint audio-video synthesis, allowing users to create professional-grade content with perfectly synchronized dialogue and ambient sound in a single generation pass.
Key Features
- Unified Transformer Architecture: A 40-layer self-attention model that processes text, image, and audio tokens simultaneously for superior coherence.
- Blazing Fast Inference: Powered by DMD-2 distillation and MagiCompiler, the model generates 1080p video in approximately 38 seconds.
- Native Audio-Video Sync: Automatically generates perfectly synchronized dialogue, Foley effects, and ambient sounds without the need for post-production dubbing.
- Multilingual Lip-Sync: Provides ultra-low Word Error Rate (WER) lip-syncing across 7 languages, including English, Mandarin, Japanese, and more.
- Fully Open Source: Offers complete access to the base model, distilled versions, and inference code, supporting self-hosting and custom fine-tuning.
- High-Quality Output: Capable of producing 1080p cinema-grade video with advanced physics simulation for fluid and cloth movement.
