happy-horses.io

happy-horses.io is an open-source AI video generation tool that creates videos with synchronized audio from text prompts or reference images. It uses a unified 40-layer Transformer architecture that processes video and audio tokens simultaneously, eliminating the need for separate audio post-processing. The tool generates videos up to 2K resolution with durations from 4 to 15 seconds, supporting both text-to-video and image-to-video workflows.

The platform stands out with its joint audio-video generation capability, producing dialogue, ambient sound, and Foley effects alongside video frames. It features 8-step fast inference through DMD-2 distillation, multilingual lip-sync support for seven languages, and diverse aesthetic styles ranging from photorealistic to anime and cyberpunk. The model ranks highly on benchmark leaderboards for both text-to-video and image-to-video generation.

Content creators, social media managers, and video professionals benefit most from happy-horses.io. It's particularly useful for creating promotional videos, prototyping visual concepts, and producing multilingual content without reshooting. The open-source nature allows technical users to fine-tune and deploy the model on their own infrastructure while the web interface provides accessible video generation for non-technical creators.
