HappyHorse API: What HappyHorse 1.1 Costs per Second, How to Get Access on Alibaba Cloud, and Every Other Way to Call It (November 2026)

HappyHorse is Alibaba's video model with sound: HappyHorse 1.1 makes clips of 3 to 15 seconds at 480p, 720p or 1080p from a prompt, a first frame or up to nine reference images, and Alibaba sells it per second through Alibaba Cloud Model Studio, at $0.14 a second for 720p in its Singapore region and about $0.124 in its other regions. fal and Replicate charge $0.14 a second at 720p with no Alibaba Cloud account. On GenMagic, a 5-second clip at 720p costs $0.74 today, from the same balance as every other video model.

This guide covers what HappyHorse is, how Alibaba prices it, getting access from Alibaba Cloud, the routes without an Alibaba Cloud account, working requests, limits and gotchas, and which route fits which job.

A note on who wrote this: GenMagic runs HappyHorse 1.1 and 1.0 and is one of the routes compared here; its prices come from its live catalog. Alibaba's figures were read on Alibaba Cloud's own price sheet, text-to-video API reference, reference-to-video API reference and model overview on November 10, 2026; other platforms' prices on each one's own model page the same day.

The short answer

• Alibaba direct: Model Studio, per second, asynchronous. HappyHorse 1.1 costs $0.07 (480p), $0.14 (720p) and $0.18 (1080p) a second in Singapore, with 10 free seconds for new users; in Frankfurt, Virginia, Tokyo and Beijing about $0.062, $0.124 and $0.165, with no free quota.
• No Alibaba Cloud account: fal and Replicate at $0.14 (720p) and $0.18 (1080p) a second; OpenRouter lists it from $0.0988 a second.
• On GenMagic: $0.15 a second at 720p and $0.19 at 1080p today, with sound, from one balance that also pays for Veo, Kling, Seedance and Wan, in a studio, the API, n8n, Zapier and MCP.
• Free to try: 10 seconds on Alibaba's Singapore region; $0.50 of starter credit on GenMagic with a verified email.

What HappyHorse is

Alibaba launched HappyHorse 1.0 in a limited beta on April 28, 2026, built by its Alibaba Token Hub unit, with "synchronized audio-visual" output: lip-synced dialogue, ambient sound and voice performances, in clips of up to 15 seconds at 1080p. HappyHorse 1.1 followed with a 480p tier and is now the model Alibaba recommends for text-to-video in Model Studio.

Clips are MP4 at 24 frames a second, in nine aspect ratios from 21:9 to 9:21. The prompt "supports any language" and runs up to 5,000 characters. Alibaba's own overview points to its other family, Wan 3.0, for clips longer than 15 seconds (up to 30) and for references that include video or audio; our Wan 3.0 API guide covers it.

In our own character test, HappyHorse 1.1 was the most expressive of four reference models and the least literal: the character stayed recognisable but drifted toward a bolder cartoon style.

How Alibaba prices it

Model Studio bills each second of video, by resolution and region, and does not charge failed requests:

The free quota is offered only in Singapore and lasts 90 days from activation or the model's release, whichever is later. HappyHorse 1.0's video editing bills both the input and the output video by the second. A 5-second clip of HappyHorse 1.1 at 720p comes to $0.70 in Singapore and about $0.62 elsewhere.

Getting access from Alibaba Cloud

1. Open an Alibaba Cloud account and activate Model Studio in the region you will call. The model, the endpoint and the API key must all belong to the same region, or the call fails.
2. Create an API key in that region's Model Studio console and keep it in an environment variable such as DASHSCOPE_API_KEY.
3. Start a task, then poll it. Every HappyHorse call is asynchronous and needs the X-DashScope-Async: enable header:

curl 'https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com/api/v1/services/aigc/video-generation/video-synthesis' \
  -H 'X-DashScope-Async: enable' \
  -H "Authorization: Bearer $DASHSCOPE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "happyhorse-1.1-t2v",
    "input": {"prompt": "A street violinist plays under a bridge at dusk, then lowers the bow and says to a passer-by, \"One more?\" Echoing city ambience, slow push-in."},
    "parameters": {"resolution": "720P", "ratio": "16:9", "duration": 5}
  }'

The answer carries a task_id; poll GET /api/v1/tasks/{task_id} about every 15 seconds until SUCCEEDED. Alibaba says a clip typically takes one to five minutes. The model ids are happyhorse-1.1-t2v, happyhorse-1.1-i2v (one first-frame image) and happyhorse-1.1-r2v (one to nine reference images, named in the prompt as [Image 1], [Image 2] and so on), and the same with 1.0, plus happyhorse-1.0-video-edit.

For individuals, Alibaba's launch post names its consumer Qwen App as the way to try it. Several other sites use the HappyHorse name for their own monthly plans and credit packs; they are resellers with their own prices, so check who runs a site before you pay it.

HappyHorse without an Alibaba Cloud account

fal and Replicate match Alibaba's Singapore price and spare you the Alibaba Cloud account and its region rules. GenMagic costs more per second than Alibaba's own API, in return for one balance across every video, image and voice model, a studio where you see the price before you generate, and the same models in n8n, Zapier and AI assistants.

Calling HappyHorse through GenMagic

The model ids are alibaba/happyhorse-1.1 ( HappyHorse 1.1) and alibaba/happyhorse-1.0 ( HappyHorse 1.0), at 720p or 1080p, 3 to 15 seconds.

curl https://genmagic.co/api/v1/videos \
  -H "Authorization: Bearer $GENMAGIC_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "alibaba/happyhorse-1.1",
    "prompt": "A street violinist plays under a bridge at dusk, then lowers the bow and says to a passer-by, \"One more?\" Echoing city ambience, slow push-in.",
    "duration": 5,
    "resolution": "720p",
    "aspect_ratio": "16:9"
  }'

It answers at once with a job id; poll GET https://genmagic.co/api/v1/videos/{id} until completed, and the answer carries a hosted url (kept with the clip, not purged after 24 hours) and what the clip cost. Nothing is charged until the clip is delivered, and a failed clip costs nothing. Add "image" to open on your picture, or pass up to nine image URLs in "references" and name them in the prompt ("the woman in Image 1"). Set "generate_audio": false for a silent clip.

Limits and gotchas

• Watermark on by default on Alibaba's API: a "HappyHorse" mark in the lower-right corner unless you pass "watermark": false.
• Links expire in 24 hours on Alibaba's API, and task ids after 24 hours too, so download each clip when it is done.
• The region is part of the key. A Singapore key does not call the Frankfurt endpoint; pick the region before you build.
• No free quota outside Singapore, and only 10 seconds there.
• Fifteen seconds is the ceiling. For one continuous take up to 30 seconds, use Wan 3.0 instead.
• Reference order matters. Images are named in the prompt by their position in the list, so keep the list and the prompt in the same order.

Which route to pick

• The lowest price per second, and you are happy on Alibaba Cloud: Model Studio outside Singapore, from about $0.062 a second at 480p.
• A quick test with no card on Alibaba Cloud: the 10 free seconds in Singapore.
• No Alibaba Cloud account, from your own code: fal or Replicate, at Alibaba's Singapore price.
• HappyHorse beside every other video model on one balance, in a studio, n8n, Zapier or an AI assistant: GenMagic, at $0.15 a second at 720p today.

Questions

Is there a HappyHorse API? Yes. Alibaba sells HappyHorse 1.1 and 1.0 through Alibaba Cloud Model Studio's video synthesis endpoint, as text-to-video, first-frame, reference and (for 1.0) video-editing models, and platforms such as fal, Replicate and OpenRouter resell it.

How much does the HappyHorse API cost? On Alibaba's own API, HappyHorse 1.1 costs $0.14 a second at 720p in Singapore and about $0.124 in its other regions, so a 5-second clip costs about $0.62 to $0.70.

How much is HappyHorse on GenMagic? A 5-second clip at 720p with sound costs $0.74 today, and $0.96 at 1080p, from a balance you top up from $5. Top-up credit never expires.

Can I use HappyHorse for free? Alibaba gives new Model Studio users 10 free seconds in its Singapore region, for 90 days. A new GenMagic account gets $0.50 of credit once its email is verified.

Does HappyHorse make sound? Yes. Both versions generate sound with the picture, including dialogue with lip-sync, ambience and effects.

What is the difference between HappyHorse 1.0 and 1.1? 1.1 adds a 480p tier and costs less at 1080p ($0.18 against $0.24 a second in Singapore); 1.0 adds a video-editing model. Alibaba recommends 1.1 for new text-to-video work.
