Frequently Asked Questions

Is HappyHorse 1.0 free to use?
Currently, you can test the HappyHorse 1.0 capabilities via our Live Demo links securely on third-party arenas. Our primary goal is establishing a robust open-source approach before announcing commercial subscription platforms.
How does the 15B architecture compare to Kling 3.0?
While massive models like Kling 3.0 focus heavily on wide-angle physical simulations and momentum transfers, HappyHorse leverages a unique 15B Single-Stream Transformer specifically honed for Human-Centric Quality, offering unmatched photorealism and emotion in close-up avatars.
What makes your Lip-Sync technology different?
Competitors rely on complex audio-visual post-processing alignment. HappyHorse AI utilizes natively synchronized joint denoising out-of-the-box. This elegant process locks visual facial movements seamlessly to audio frames, yielding a historic 14.60% Word Error Rate (WER).
Can I run this model locally on an RTX 4090?
The 15B parameter model is highly optimized. We are working on providing dedicated quantized versions and open-source recipes that will make running foundational inference passes comfortably feasible on powerful consumer GPUs like the NVIDIA RTX 4090.
When will the Weights & GitHub repo be released?
We are currently in an exclusive preview phase. Official repository access and model weight distributions on HuggingFace are coming soon. Follow our updates and join the community to be the first to know!
