What is HappyHorse?
HappyHorse is a web-based AI video generator that takes text descriptions or uploaded reference images (JPG, PNG, WebP, under 35MB) as input and outputs 1080p video clips with synchronized dialogue, ambient sound, and Foley effects. The platform runs the HappyHorse 1.0 model, a 15-billion-parameter unified Transformer that denoises video and audio tokens in a single pass — no separate audio post-production.
