Question 1

What is the Happy Horse AI video generator?

Accepted Answer

HappyHorse 1.0 is a video generation model from Alibaba. It debuted under a pseudonym on the Artificial Analysis Video Arena in April 2026 and ranked first for text-to-video and image-to-video before its developer was revealed. In LazyKiwi it makes 720p or 1080p clips from a prompt or a still.

Question 2

Does HappyHorse 1.0 support image-to-video?

Accepted Answer

Yes. Upload one image and HappyHorse 1.0 keeps its composition while generating the motion in your prompt. Aspect ratio, duration and quality are set the same way as in text-to-video mode. Start and end frame pairs are not available here; use Kling v3 Omni or Wan 2.7 for those.

Question 3

Which aspect ratios and durations does HappyHorse offer?

Accepted Answer

Five aspect ratios: 16:9, 9:16, 1:1, 4:3 and 3:4. Eight durations: 3, 5, 8, 10, 15, 30, 45 and 60 seconds. Every combination works in both modes at 720p or 1080p, so one prompt can be re-run in whatever shape and length each platform needs.

Question 4

How much does HappyHorse 1.0 cost in LazyKiwi?

Accepted Answer

HappyHorse 1.0 is currently 40% off its list price. A 5-second clip costs 420 credits at 720p or 840 at 1080p, a 10-second clip 840 or 1,680, and a 15-second clip 1,260 or 2,520. Other durations are charged per second; the exact cost is shown before you generate.

Question 5

HappyHorse 1.0 or Kling v3 Omni: which should I use?

Accepted Answer

Use HappyHorse 1.0 for 1080p text-to-video with 4:3 or 3:4 framing, or a single 60-second take. Use Kling v3 Omni when the clip has to start and end on specific frames, since it adds start-and-end-frame mode. Both sit in the same LazyKiwi picker, so testing both is a two-click switch.
