Happy Horse AI

HappyHorse AI Video Generator is a platform powered by HappyHorse 1.0, an AI model that creates cinematic videos with synchronized audio from text prompts or reference images. It generates video and audio together in one step, delivering natural voiceover, ambient sound, and precise lip sync. Aimed at marketers, educators, filmmakers, and social media creators, it supports six languages and outputs up to 1080p resolution.

How it works

HappyHorse 1.0 generates video and audio simultaneously in a single pass, eliminating the need for separate audio tools or dubbing. It achieves a 14.6% Word Error Rate for lip sync, nearly 3x better than Ovi 1.1. The model uses an optimized 8-step denoising process, producing a 5-second 256p preview in about 2 seconds and full 1080p output in approximately 38 seconds.

Key capabilities

The platform supports text-to-video and image-to-video, both ranked #1 on Artificial Analysis with Elo scores of 1357 and 1392 respectively. It offers aspect ratios including 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9. Videos are generated with progressive super-resolution from 256p through 540p to full 1080p, with cinematic color grading and natural lighting.

Who it is for

HappyHorse is designed for marketing and brand content, education and training, filmmaking and creative projects, and social media content creation. It natively supports Chinese (Mandarin and Cantonese), English, Japanese, Korean, German, and French, with language understanding built into the model.
