HappyHorse AI is your complete guide to the HappyHorse video generation model — one of the first AI models to generate video and audio together in a single pass. Instead of stitching silent clips to a separate soundtrack, HappyHorse produces cinematic 1080p videos up to 15 seconds long with natively synchronized sound effects, spoken dialogue, and lip-sync across six languages.

Start from a text prompt, a single image, or up to nine reference photos to keep characters and products consistent across shots. The site covers everything you need to get started: model capabilities, benchmark results, access options and pricing, step-by-step usage guides, and real-world use cases from short-form ads to talking-avatar content.

Stay up to date on the latest releases — including news on HappyHorse 2 — with a regularly updated changelog and FAQ. Available in English, Chinese, and Japanese.
