HappyHorse 1.1 is here — 9 aspect ratios, up to 15s, audio included

A new model has landed in the video node's model list: HappyHorse 1.1, Alibaba's in-house video model.

What it does

  • Text to video — write a prompt, get a clip
  • Image to video — hand it a first frame and let it move
  • Multi-image reference — attach up to 9 reference images to lock character and object consistency

Things worth knowing

  • 9 aspect ratios: 16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4, 9:21, 21:9 — including 21:9 ultra-wide and 9:21 ultra-tall, which most models don't offer
  • Any length from 3 to 15 seconds, not just a few fixed steps
  • Audio comes built in — every clip ships with synced sound, no toggle, no surcharge
  • 720p / 1080p

Pricing

16.8 credits/sec at 720p, 21.6 credits/sec at 1080p. A 5-second 720p clip costs 84 credits.

Two notes

  • In image-to-video mode the output ratio follows your input image, so the aspect selector doesn't apply — that's the model's own rule
  • This version doesn't do video editing; it takes image references only, not video
