Our internal testing of 750+ happy horse 1.0 outputs across 25+ model variants revealed clear best practices for prompt structure, model selection, and output settings — all reflected in the workflow below.
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.

More Than Just Happy Horse 1.0
Top-Ranked Video Generation
Happy Horse 1.0 scored Elo 1333 in text-to-video and 1392 in image-to-video on Artificial Analysis. Access it alongside other models in the AI video generator canvas.
Synchronized Audio Output
Audio tokens share the same sequence as video tokens during generation, producing matched dialogue, sound effects, and ambient audio. Compare results with Seedance 2.0 side by side.
Image-to-Video Animation
Upload a reference image and Happy Horse animates it with natural motion and physics. Generate starting frames with an image model, then animate using the text to video pipeline.
Multi-Language Lip-Sync
Generate video with accurate lip synchronization across six languages for global content production. Follow the complete text to video workflow guide for prompting practices.
Chain with Other Models
Connect Happy Horse output to upscaling, face enhancement, or format conversion nodes. Use it alongside Recraft V4 for reference image generation in multi-step workflows.
