Happy Horse AI video generator: text or image to 1080p video
Alibaba's HappyHorse 1.0 in LazyKiwi: text-to-video and image-to-video, five aspect ratios, 3 to 60 seconds, 1080p by default.
HappyHorse 1.0 is a video generation model from Alibaba. It appeared under a pseudonym on the Artificial Analysis Video Arena in April 2026 and took the top spot in the text-to-video and image-to-video rankings before Alibaba was named as its developer. In LazyKiwi it runs both modes with a 2,500-character prompt, 16:9, 9:16, 1:1, 4:3 or 3:4 framing, durations from 3 to 60 seconds, and 720p or 1080p output with 1080p preselected. Specs: up to 720p or 1080p, 1080p default.

How it works
Use HappyHorse 1.0 in three steps
Open the LazyKiwi video workbench, pick HappyHorse 1.0, and generate from a prompt or a still without leaving the page.
1Pick the input
Select HappyHorse 1.0 in the model list. Type a prompt of up to 2,500 characters for text-to-video, or add one image to animate it. Both modes share one parameter panel.
2Frame and time the shot
Choose 16:9, 9:16, 1:1, 4:3 or 3:4, then a duration from 3s to 60s. Quality defaults to 1080p; switch to 720p for a cheaper draft.
3Generate and download
HappyHorse 1.0 is currently 40% off in LazyKiwi: a 5-second clip costs 420 credits at 720p or 840 at 1080p, a 10-second clip 840 or 1,680. Preview in the player and download the MP4.
Why HappyHorse 1.0
What HappyHorse 1.0 is built for
HappyHorse 1.0 pairs a full text-to-video mode with 1080p output and a 60-second ceiling. These are the capabilities the workbench actually exposes.
Inputs
Prompt alone, or prompt plus image
Text-to-video builds the whole scene from the brief: subject, setting, lighting and camera. Image-to-video keeps the composition of a still you upload and generates the motion on top of it. One 2,500-character prompt field serves both modes, so a brief written for one can be re-run in the other.
- Text → video
- Image → video
- 2,500-character prompt limit
Framing
Five aspect ratios, including 4:3 and 3:4
16:9 for YouTube and web, 9:16 for Reels, Shorts and TikTok, 1:1 for grid tiles, and 4:3 or 3:4 for feed posts and slides. The ratio is set per run, so one prompt can be generated in every shape a campaign needs.
- 16:9, 9:16, 1:1, 4:3, 3:4
- Ratio set per run
- Same prompt across formats
Duration
3 seconds to a minute
Eight durations: 3s, 5s, 8s, 10s, 15s, 30s, 45s and 60s. The 3-second option is the cheapest way to check that a prompt reads correctly before a longer run, and the 60-second ceiling covers a full-length spot or a continuous background loop.
- 3s to 60s in eight steps
- Same range in both modes
- Credits scale with length
Output
1080p by default
The workbench preselects 1080p for HappyHorse 1.0, so the first render is at delivery resolution. Drop to 720p, which costs half as many credits, to iterate on wording and motion, then switch back for the final.
- 720p or 1080p
- 1080p preselected
- 720p at half the credits

FAQ
HappyHorse 1.0 FAQ
What is the Happy Horse AI video generator?
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.
Does HappyHorse 1.0 support image-to-video?
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.
Which aspect ratios and durations does HappyHorse offer?
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.
How much does HappyHorse 1.0 cost in LazyKiwi?
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.
HappyHorse 1.0 or Kling v3 Omni: which should I use?
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.
