Happy Horse 1.0
An Alibaba-built image-to-video model offering 15-second clips at up to 1080p, available on AutorunX via EvoLink.
Picking Happy Horse as the model for a generation.
What Happy Horse does
Happy Horse 1.0 turns a still image into a 15-second animated video clip at up to 1080p resolution, adding motion to a photo you supply rather than generating new visual content from text alone. It's a straightforward image-to-video option in the AutorunX model lineup.
It's positioned as an alternative image-to-video engine alongside Kling, Hailuo, and Grok Imagine — worth trying on a shot where those models' particular motion style or pricing doesn't fit, since different image-to-video models can produce noticeably different motion characteristics from the same source photo.
Key features
15-second image-to-video clips
Each generation animates a supplied still image into a 15-second clip, longer than the 6-10 second default of some other image-to-video models on AutorunX.
720p-1080p resolution
Output resolution runs from 720p up to 1080p, suitable for standard social and web video delivery without needing an upscale pass.
EvoLink cloud access
Happy Horse runs through the same EvoLink gateway as several other AutorunX cloud video models, so it fits into the same generation workflow as Kling, Hailuo, or Seedance.
Alternative motion style
As a distinct model from Alibaba's better-known Wan line, it offers a different take on image-to-video motion, worth comparing against other options for a given shot.
How Happy Horse works
Happy Horse 1.0 is an image-to-video model: it takes a still reference image and animates it into a 15-second video clip, rather than generating a scene purely from a text prompt. As with other image-anchored models, the subject and composition come from the source photo, and the prompt guides motion and behavior within that fixed frame.
It's made available on AutorunX through EvoLink, the same cloud model gateway that hosts several of AutorunX's other proprietary video models (Kling, Hailuo, Seedance, Grok Imagine). Output resolution runs 720p-1080p, and each generation produces a single 15-second clip.
Because publicly documented technical details on Happy Horse's architecture are limited relative to more established releases from the same developer, this page sticks to the confirmed specifications rather than speculating on internal model design.

Who built Happy Horse
Alibaba
www.alibabacloud.comHappy Horse is a video generation model published via EvoLink's model catalog and attributed to Alibaba. Public details about the team and release history behind it are limited compared to Alibaba's better-documented Wan line, so we're not able to independently verify a fuller company backstory here beyond what EvoLink lists — Happy Horse should be treated as a newer, less widely documented release from Alibaba's video AI efforts.

Tips for better results with Happy Horse
Start from a well-composed source image
Since there's no text-to-video mode, make sure the subject and framing you want are already correct in the image you upload.
Compare against other image-to-video models
Try the same source image through Happy Horse and another available image-to-video model to see which motion style suits the shot before committing.
Use the full 15 seconds intentionally
Plan the motion or action to use the full clip length rather than front-loading everything into the first few seconds.
Keep expectations grounded in confirmed specs
Since public documentation on this model is thinner than better-known releases, rely on AutorunX's confirmed specs (15s, 720p-1080p, image-to-video only) rather than assuming feature parity with other Alibaba models.
