Happy Horse AI

Happy Horse AI is a browser-based AI video generation platform for creators, marketers, developers, and production teams. The HappyHorse 1.1 model supports text-to-video, image-to-video, and reference-to-video workflows with 720P or 1080P output, 3 to 15 second durations, optional audio, aspect-ratio controls, and clear credit estimates. A unified workspace organizes task status, previews, completed videos, and downloads. Developers can use the documented Happy Horse API to submit supported generation tasks, monitor status, and integrate model video creation into apps, SaaS products, internal tools, and repeatable content pipelines.
