HappyHorse 1.1 brings improved motion coherence, prompt adherence, and scene transitions over the 1.0 release. All four modes — text-to-video, image-to-video, reference-to-video, and video-edit — are available at both 720p and 1080p via Kinovi's infrastructure.
Closed playground beta
HappyHorse 1.1 is currently available only inside the muapi playground on the Pro and Business plans — API-key access opens in a later public release.
