What is HappyHorses.io?

Happy horse 1.0 is an open-source AI video generation model for producing synchronized video and audio from text or image prompts.Built as a unified multimodal 15B-parameter transformer, it jointly generates frames and aligned dialogue/ambient sound with native lip-sync support for seven languages (English, Mandarin, Cantonese, Japanese, Korean, German, French).

Released artifacts include base and distilled checkpoints, a super-resolution module, and inference code with commercial-use permissions for self-hosting, fine-tuning, and deployment.Outputs target 1080p short clips (5–8s) in common aspect ratios (16.9, 9.16), suitable for social, advertising, and short-form cinematic workflows.

Runtime optimizations—8-step distillation and FP8 quantization—reduce memory and accelerate inference for single-GPU deployment on NVIDIA H100/A100 (≥48 GB VRAM recommended).Benchmarks report improved prompt alignment and lower word error rate versus comparable open models; typical users include researchers, developers, content creators, and post-production teams seeking reproducible, self-hosted generative video pipelines.
