What Makes HappyHorse-1.0 Different
A 15B-parameter unified Transformer that jointly produces video and synchronized audio — setting a new standard for open-source AI video generation.
Joint Audio-Video Synthesis
HappyHorse-1.0 generates synchronized video and audio in a single pass — lip-synced dialogue, ambient sound effects, and music without any extra audio syncing step.
Native 1080p Cinematic Quality
Produce photorealistic videos at up to 1080p resolution with authentic material textures, physically accurate lighting, and natural motion dynamics across every frame.
Multi-Modal Input
Create videos from text prompts, reference images, or a combination of both. HappyHorse-1.0 supports 5+ input modalities including text, images, video fragments, and audio references.
DMD-2 Distilled Inference
Powered by DMD-2 distillation requiring only 8 inference steps and MagiCompiler acceleration, HappyHorse-1.0 generates full 1080p video in approximately 38 seconds.
Multi-Shot Storytelling
Go beyond single clips with breakthrough multi-shot planning. HappyHorse-1.0 automatically splits prompts into cinematic sequences for polished, story-driven video output.
7-Language Lip-Sync
Industry-leading multilingual support: English, Mandarin, Cantonese, Japanese, Korean, German, and French — with accurate lip synchronization and low word error rate.
Create Your First AI Video in 3 Steps
No video editing experience required. Just describe what you want to see and hear.
Describe Your Vision
Type your prompt in plain English — or upload a reference image. Include subject, action, setting, mood, and camera style. HappyHorse-1.0 understands cinematic language naturally.
"A lone astronaut walking across a red desert at golden hour, wide shot, cinematic, ambient wind sounds"
Customize Settings
Choose aspect ratio (16:9, 9:16, 1:1), duration (5–15 seconds), resolution (720p or 1080p), and audio options. Enable prompt expansion for richer cinematic output or multi-shot planning for story sequences.
Generate & Download
Click generate and your video with synchronized audio is ready in under a minute. Download as MP4 at up to 1080p, or iterate with new prompts. Each generation produces both video and matching audio in a single pass.

About HappyHorse-1.0
HappyHorse-1.0 is a 15-billion-parameter AI video generation model built on a unified Transformer architecture. Unlike conventional systems that treat picture and sound as separate stages, HappyHorse-1.0 is designed to generate them together in a single pass, which is why it has drawn so much attention in blind video arena tests.
Public reporting now ties the project to Alibaba ATH, with Zhang Di and a team of video-model engineers behind the work. The appeal is not just the mystery around the launch. It is the combination of strong image-to-video results, more faithful prompt handling than many rivals, and a release strategy that is still unfolding in public.
HappyHorse-1.0 supports text-to-video, image-to-video, and reference-to-video workflows. Whether you are testing ad concepts, animating still images, building short narrative clips, or evaluating the model against Seedance and Kling, HappyHorse-1.0 is most interesting right now as a high-upside tool that is becoming easier to access but still needs careful evaluation before full production rollout.
Technical Highlights
Unified 40-Layer Self-Attention Transformer
HappyHorse-1.0 uses a single 15B-parameter Transformer with 40 layers of self-attention to jointly model video frames and audio waveforms. This unified architecture ensures temporal alignment between visual and auditory elements without requiring separate models or post-processing pipelines.
DMD-2 Distillation (8 Steps)
Through DMD-2 distillation, HappyHorse-1.0 achieves high-quality output in only 8 inference steps — dramatically reducing computation time. Combined with MagiCompiler-optimized inference, a full 1080p video generates in approximately 38 seconds.
7-Language Lip Synchronization
The model natively supports lip-synced dialogue in English, Mandarin, Cantonese, Japanese, Korean, German, and French. Word error rate is industry-leading across all supported languages, making HappyHorse-1.0 suitable for international content production.
Public Release Still Evolving
The project has been discussed as open source, but the public release story is still incomplete. Weights, inference tooling, and broad access should be treated as evolving rather than fully settled.
