|---|---|---|---|---|
| prompt | Text prompt describing the desired video content. Supports any language input, excess characters will be automatically truncated | string | Yes | - |
| duration | Specifies the video duration in seconds (integer) | integer | No | 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 |
| ratio | Specifies the aspect ratio for the generated video | string | No | 16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4, 9:21, 21:9 |
| resolution | Specifies the resolution tier for the generated video | string | No | 720P, 1080P |
| seed | Random number seed. To improve reproducibility of generated results, it is recommended to fix the seed value. Note: Due to the probabilistic nature of model generation, even using the same seed cannot guarantee completely identical results each time | integer | No | - |

- alibaba/happyhorse-1.0-i2v: [Core Function] HappyHorse 1.0 I2V is a streamlined image-to-video model. [Strengths] It generates high-quality 720P/1080P video (3-15s) from an image efficiently, with native audio support. [Best For] Highly recommended for: rapid image animation and robust character motion. [Limitations] Does not support complex video continuation like Wan 2.7 I2V. [Routing] Use when the user requests ‘HappyHorse’ or a streamlined image animation.
- alibaba/happyhorse-1.0-r2v: [Core Function] HappyHorse 1.0 R2V is a reference-to-video model. [Strengths] It excels at maintaining character consistency using up to 9 reference images while generating new video actions based on a prompt. [Best For] Highly recommended for: character-consistent storytelling and generating multiple scenes with the same subject. [Limitations] Do NOT use if you simply want to animate a single image exactly as it is (use HappyHorse I2V instead). [Routing] Use this when the user provides reference images to dictate character/subject appearance in a newly generated action.
- alibaba/happyhorse-1.0-video-edit: [Core Function] HappyHorse 1.0 Video Edit is a streamlined video editing model. [Strengths] It provides high-quality video editing capabilities (with or without reference images) within the highly optimized HappyHorse architecture. [Best For] Highly recommended for: fast, high-quality video modifications, especially when the user explicitly requests HappyHorse. [Limitations] May lack the deep instruction-based logical replacement mechanics of Wan 2.7 Video Editing. [Routing] Route to this model when the user explicitly requests ‘HappyHorse’ for their video editing task.
- alibaba/happyhorse-1.1-t2v: [Core Function] HappyHorse 1.1 T2V is Alibaba’s latest streamlined text-to-video model. [Strengths] It generates 720P/1080P video with native audio support, 3-15 second duration, and an expanded set of aspect ratios including 4:5, 5:4, 9:21, and 21:9. [Best For] Highly recommended for: fast HappyHorse text-to-video generation, social video formats, and high-throughput content creation. [Limitations] It does not expose custom audio controls; use Wan 2.7 T2V when custom audio input is required. [Routing] Prefer this model when the user explicitly requests HappyHorse text-to-video or wants the latest HappyHorse generation quality.
- alibaba/happyhorse-1.1-i2v: [Core Function] HappyHorse 1.1 I2V is Alibaba’s latest streamlined first-frame image-to-video model. [Strengths] It turns a single image into high-quality 720P/1080P video with native audio support and 3-15 second duration; output aspect ratio follows the first frame image. [Best For] Highly recommended for: rapid image animation, product motion previews, and simple character or scene animation. [Limitations] It does not accept an explicit ratio parameter; use T2V or R2V when you need a fixed generated aspect ratio. [Routing] Prefer this model when the user provides one image and requests HappyHorse image animation.
- alibaba/happyhorse-1.1-r2v: [Core Function] HappyHorse 1.1 R2V is Alibaba’s latest reference-image-to-video model. [Strengths] It uses 1-9 reference images to preserve subject or character appearance while generating new video actions, supports 720P/1080P output, 3-15 second duration, and expanded aspect ratios including 4:5, 5:4, 9:21, and 21:9. [Best For] Highly recommended for: character-consistent storytelling, reference-based product shots, and multi-image subject composition. [Limitations] Do NOT use if the user simply wants to animate a single image exactly as provided; use HappyHorse I2V instead. [Routing] Use when the user provides one or more reference images and asks for a newly generated HappyHorse video.
