We are excited to announce that Happy Horse 1.0 API is now available on Poyo.ai. Developers can use Alibaba's cinematic AI video generation model through one unified Poyo API workflow for both text-to-video and first-frame image-to-video generation.
Happy Horse 1.0 is designed for short video clips with expressive camera movement, strong prompt adherence, and stable scene composition. On Poyo.ai, it is available with 720p and 1080p output, 3-15 second durations, async task status, and optional callback delivery.
What Makes Happy Horse 1.0 Useful
Happy Horse 1.0 focuses on practical short-form video generation. It works well when a product, creative tool, or internal pipeline needs fast motion concepts without building a separate provider integration.
Cinematic Text-to-Video
Send a natural-language prompt with the public model ID happy-horse to generate cinematic short videos from text. Happy Horse supports common text-to-video aspect ratios, including 16:9, 9:16, 1:1, 4:3, and 3:4.
Use it for:
- Social video clips and visual hooks
- Ad concepts and campaign variations
- Storyboard motion studies
- Product launch scenes
- Creative concept testing
First-Frame Image-to-Video
For workflows that need tighter visual control, send one image_url or one item in image_urls. The image becomes the first frame, while an optional prompt can guide motion, camera behavior, subject movement, or style.
This is especially useful for:
- Product image animation
- Character or portrait motion
- Brand asset videos
- Concept art animation
- Landing page and marketplace motion assets
Key Features on Poyo.ai
Happy Horse 1.0 is exposed through the same production-friendly Poyo API pattern used by other generation models.
- Model ID:
happy-horse - Input modes: text-to-video and image-to-video
- Output resolutions: 720p and 1080p
- Duration: 3-15 seconds
- Text-to-video aspect ratios: 16:9, 9:16, 1:1, 4:3, 3:4
- Workflow: asynchronous submit, task status polling, and optional
callback_url - Use cases: creator apps, marketing workflows, video prototyping, product motion assets, and batch generation
Pricing
Happy Horse 1.0 uses simple per-second credit pricing on Poyo.ai:
| Resolution | Credits | Example 5-Second Cost |
|---|---|---|
| 720p | 16 credits/second | 80 credits |
| 1080p | 32 credits/second | 160 credits |
This makes it easy to budget drafts and final renders before you submit a task. Choose 720p for lower-cost iteration, then switch to 1080p when you need sharper final output.
Getting Started with Happy Horse 1.0 API
Step 1: Create an API Key
Create a Poyo.ai account and generate an API key from the dashboard.
Step 2: Choose Your Workflow
Use model: "happy-horse" for both workflows. Send a prompt for text-to-video, or include an image URL for image-to-video.
{
"model": "happy-horse",
"input": {
"prompt": "A cinematic tracking shot of a runner moving through a neon city street at night",
"resolution": "1080p",
"duration": 5,
"aspect_ratio": "16:9"
}
}
For image-to-video, include a first-frame image:
{
"model": "happy-horse",
"input": {
"prompt": "Slow camera push-in with subtle product lighting and smooth background motion",
"image_url": "https://example.com/product-first-frame.png",
"resolution": "720p",
"duration": 5
}
}
Step 3: Submit and Receive the Result
Happy Horse generation runs asynchronously. Submit a task, poll the status endpoint with the returned task_id, or provide callback_url so your application receives the final video automatically.

Why Use Happy Horse 1.0 Through Poyo.ai
Poyo.ai helps teams integrate Happy Horse 1.0 without adding another provider-specific workflow.
Unified Model Access
One Poyo API key gives you access to Happy Horse and the broader Poyo model catalog. You can keep authentication, billing, task status, and callback patterns consistent across models.
Predictable Cost Control
Per-second pricing makes it straightforward to estimate generation cost before launching a workflow. Teams can test at 720p, reserve 1080p for final assets, and keep short-form video generation under control.
Production-Friendly Async Flow
The async task model is built for apps, dashboards, and batch pipelines. Submit jobs, monitor status, and handle completed videos through polling or callback delivery.
