Generate Video and Audio with Happy Horse 1.0

Happy Horse 1.0 is a 15-billion-parameter unified Transformer that generates both video and synchronized audio in a single forward pass. It supports text-to-video and image-to-video inputs at native 1080p resolution, producing clips with dialogue, ambient sound, and Foley effects. Wireflow connects Happy Horse 1.0 as a node on the visual canvas so you can chain it with other models, add post-processing, and run complex video workflows without switching tools.

The model ranked #1 globally on the Artificial Analysis Video Arena in both text-to-video (Elo 1333) and image-to-video (Elo 1392) categories under blind user voting. It supports lip-sync in six languages: English, Chinese, Japanese, Korean, German, and French. As a fully open-source release with commercial-use rights, it can be self-hosted, fine-tuned, and deployed on your own enterprise infrastructure.
