Happy Horse 1.1 is exposed in GENGEN as one public video model with three modes: text_to_video, image_first_frame, and reference_to_video. GENGEN maps the public model and selected mode to the provider-specific upstream model ID internally. The model supports 720P and 1080P output, 3-15 second durations, optional watermarks, and reproducible seeds. In GENGEN, Happy Horse uses the shared video task endpoint and returns happyhorse11:<remote_id> public task IDs.
