happyhorse ai

Happy Horse AI is a video generation service that creates up to 15-second multi-shot videos with native audio from text prompts or reference images. Powered by the Happy Horse 1.0 model, it jointly generates video and audio in a single unified pass, eliminating the need for separate audio post-production. It is designed for creators, hobbyists, and professionals who want fast, high-quality video content for social media, ads, or presentations.

How it works

Happy Horse 1.0 is a single self-attention Transformer that jointly denoises text, video, and audio tokens in one unified sequence. This architecture replaces the multi-stream complexity of older models, ensuring perfect alignment between modalities. It supports both text-to-video and image-to-video generation, with the latter conditioning on a reference image latent to preserve subject identity and visual style while adding fluid motion.

Key capabilities

The service offers a streamlined three-step process: describe your vision with a clear prompt, generate and refine the multi-shot sequence with dynamic camerawork, then export and share high-definition output. Users can choose from aspect ratios including 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1. The model achieves state-of-the-art inference speed on H100 GPUs for 5-second video generation, going from prompt to video in under a minute.
