Apache 2.0 license · 15B parameters · Commercial use allowed
What's Open-Sourced
Happy Horse 1.0 releases four components publicly — giving researchers, developers, and creators full access to the model stack.
Base Model
The full 15B-parameter base model weights, trained on a large-scale video dataset with joint audio generation.
Distilled Model
A smaller, faster distilled version of Happy Horse 1.0 optimized for lower-resource inference without sacrificing quality.
SR Module
The Super Resolution module used to upscale generated video to 1080p native output.
Inference Code
Full inference pipeline code including text-to-video, image-to-video, and audio generation scripts.
Model Components
Each component is independently downloadable from the GitHub repository.
HappyHorse-1.0-Base
Full base model for text-to-video and image-to-video generation with joint audio.
HappyHorse-1.0-Distilled
Distilled model for faster inference on consumer hardware.
HappyHorse-SR
Super resolution upscaler for 1080p output quality.
How to Self-Host Happy Horse 1.0
- 1
Clone the Repository
git clone https://github.com/happyhorse-ai/happyhorse && cd happyhorse - 2
Install Dependencies
pip install -r requirements.txt — requires Python 3.10+, CUDA 11.8+, and at least 24GB VRAM for the base model. - 3
Download Model Weights
Run python download_weights.py to fetch the base model or distilled model from Hugging Face. - 4
Run Inference
python generate.py --prompt "Your prompt here" --model base --audio true
Why Use the Cloud Instead of Self-Hosting?
Self-hosting is powerful — but the cloud removes all the friction.
No GPU Required
Self-hosting Happy Horse 1.0 requires 24GB+ VRAM. The cloud version runs it for you — no hardware needed.
Multi-Model Access
Switch between Happy Horse 1.0, Seedance 2.0, Kling, and more — all from one platform.
