Overview
What is Happyhorse-1.0 API?
HappyHorse 1.0 is a unified multimodal AI video generation model developed by Alibaba's ATH-AI. It utilizes a single-stream Transformer architecture to generate 1080p high-definition video and native audio simultaneously in a single forward pass. Unlike traditional models that require separate audio synthesis and lip-syncing steps, HappyHorse 1.0 generates dialogue, environmental sounds, and sound effects perfectly synced with the visuals. It supports sub-pixel level lip-syncing for seven languages and currently ranks first in Artificial Analysis benchmarks for both text-to-video and image-to-video generation.
