HappyHorse 1.1 T2V

HappyHorse 1.1 T2V is Alibaba Cloud Model Studio’s text-to-video model. It generates a 24 fps MP4 video with synchronized audio from a text prompt through AnyFast’s asynchronous video API. T2V means text-to-video: the request contains a text prompt and does not require an input image.

Key capabilities

Aspect ratio - 16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4, 9:21, or 21:9
Reproducibility control - Set a random seed
Watermark control - Choose whether to add the HappyHorse watermark

Workflow

POST /v1/video/generations -> task_id
GET /v1/video/generations/{task_id} -> poll until complete
