Try Happy Horse 1.1 - Text to Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: happyhorse-1.1-t2v HappyHorse 1.1 text-to-video generates video from a text prompt at 720P or 1080P with durations from 3 to 15 seconds and configurable aspect ratio. It accurately comprehends text semantics to output high-quality video that is fluid, natural, and rich in detail.

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
