Happy Horse is Alibaba's AI video model family: it generates up to 15 seconds of 1080p video from text, an image or reference pictures, with dialogue and sound produced in the same pass, and version 1.1 is the refined release that followed the 1.0 model that topped blind video rankings in April 2026. As of October 2026 Happy Horse is not one of the models inside VIBE, so this guide explains what it does and shows the closest models you can use today.
In one sentence
Happy Horse is an Alibaba AI video model that creates video and synchronized audio together from text, images or reference photos, with version 1.1 improving motion, skin detail and instruction following over 1.0.
What is Happy Horse and who made it?
Happy Horse appeared in April 2026 under an anonymous name and climbed to the top of the public Artificial Analysis Video Arena, a leaderboard where people vote on pairs of clips without knowing which model made them. On April 10, 2026 Alibaba confirmed the model was its own, built inside Alibaba Token Hub, the group the company created for its AI products. Reports at launch described a 15-billion-parameter transformer that handles text, images, video frames and audio together in a single sequence.
That design is why the model is talked about so much: sound is not added afterwards. Footsteps, speech, room tone and music come out of the same generation as the picture, so a character's mouth movement and the dialogue line up. Alibaba's wider AI work is covered on Alizila, and the company background is on Wikipedia. If you want the sister model that VIBE does carry, read our guide to WAN 3.0 in VIBE.

What are the Happy Horse 1.1 specs?
Specs below come from the maker's launch coverage and from published model guides, so treat them as vendor-reported rather than independently tested. Happy Horse 1.1 has no public consumer app of its own at the time of writing; it is offered through developer APIs and through third-party creative tools.
- Clip length: 3 to 15 seconds per generation.
- Resolution: 720p and 1080p output.
- Input modes: text-to-video, image-to-video, and reference-to-video with up to 9 reference images.
- Aspect ratios: 16:9 for landscape and 9:16 for vertical, plus 1:1, 4:3 and 3:4 among others.
- Audio: dialogue, sound effects, ambience and music generated together with the video, with lip-sync reported for English, Mandarin, Cantonese, Japanese, Korean, German and French.
- Editing: a video-edit endpoint is offered through the developer API.
How is Happy Horse 1.1 different from 1.0?
Version 1.1 keeps the same core architecture as 1.0 and focuses on polish. Published guides describe five practical changes, which matter most if you generate people, action or long prompts. The table summarizes them.
| Area | Happy Horse 1.0 | Happy Horse 1.1 |
|---|---|---|
| Motion | Occasionally sluggish pacing | More physically grounded, especially action and particles |
| Skin and surfaces | Sometimes over-sharpened | More natural skin and reflections |
| Prompt following | Could simplify long prompts | Handles longer, more detailed instructions more reliably |
| Camera | Tended to zoom in even when not asked | Zooms only when the prompt asks for it |
| Audio | Joint audio and video | Richer sound, better matched to scene mood |
These are vendor-side descriptions, and artifacts are described as rarer, not gone. As with every AI video model, the practical test is to generate your own scene and compare. That is why we suggest running the same prompt on two models before you commit to a style.

Is Happy Horse available in VIBE?
No. As of October 2026 the VIBE model list contains Wan 3.0, Veo 3.1 Fast, Kling 3 Pro, Kling 3 Standard, Sora 2 Pro, Seedance Pro Fast, LTX Video, Luma Dream Machine, Wan 2.6 and PixVerse, and Happy Horse is not on it. We only describe a model as available in VIBE when it is in the app, so use this guide to understand the model and use the steps below to get a comparable result today.
- Open VIBE on iOS, Android or the web; there is no login required to start.
- Pick a free model such as Seedance Pro Fast or a premium one such as Kling 3 Pro or Veo 3.1 Fast.
- Paste a prompt that names the subject, camera move, light and, if the model supports it, the sound.
- Generate, then re-run the same prompt on a second model and keep the better clip.
- Export the vertical 9:16 version for TikTok, Reels or YouTube Shorts.
Which VIBE models are closest to Happy Horse?
Three VIBE models cover most of what people want from Happy Horse. Veo 3.1 Fast from Google DeepMind creates 8-second 1080p clips with native audio. Kling 3 Pro from Kuaishou reaches 15 seconds at 1080p with audio. Wan 3.0, Alibaba's own newer model, goes up to 30 seconds with audio and accepts text, reference images or a photo. For free tries, Seedance Pro Fast makes 8-second 720p clips with image-to-video, and you can explore all of them in the model list.
| Model | Maker | Max length | Audio | Input |
|---|---|---|---|---|
| Wan 3.0 | Alibaba | 30 s | Yes | Text, reference images, photo |
| Kling 3 Pro | Kuaishou | 15 s | Yes | Text, photo |
| Veo 3.1 Fast | Google DeepMind | 8 s | Yes | Text |
| Seedance Pro Fast | ByteDance | 8 s (720p) | No | Text, photo |
| Happy Horse 1.1 | Alibaba | 15 s | Yes | Text, photo, references (not in VIBE) |

How do you prompt a Happy Horse style video?
The strengths reported for Happy Horse are motion, natural skin and sound, so the prompts that suit it describe those things on purpose. The same habits work on the VIBE models above, and our guide to the best AI video models shows how each one reacts.
- Say what moves. Name the action, the speed and the physics, such as water spraying or dust lifting.
- Write the sound. Add one line for ambience and one for dialogue in quotation marks.
- Control the camera. Ask for a tracking shot or a push-in, and say no zoom if you do not want one.
- Keep one subject. A single clear character holds together better than a crowd.
- Use a reference photo. Image-to-video keeps a face or product consistent across clips.
βOne continuous 20-second take: a baker pulls a tray of croissants from a stone oven at dawn, turns and slides it onto a wooden counter as the first customer walks in, warm tungsten light, flour dust floating in the air, 35mm lens, slow handheld push-in. Ambient sound: oven crackle and the shop door bell.β
βVertical 9:16 slow-motion shot of a skateboarder landing a kickflip on wet pavement at dusk, water spraying from the wheels, sparks of orange streetlight on the droplets, low camera angle, crisp motion, no camera zoom.β
Prompts are written in English because the models are trained mostly on English captions, even when you publish the clip in another language.

Do video model rankings tell you which model is best?
Leaderboards such as the Artificial Analysis Video Arena are useful because real people compare clips blind, but they measure preference on a set of test prompts at one moment. Happy Horse 1.0 was reported first in text-to-video and image-to-video without audio, and level with ByteDance's Seedance 2.0 when audio was judged. Positions change as new models arrive, so check the current board rather than a screenshot.
The better question for a creator is which model gives the clip you need for your platform. A funny 8-second vertical clip for TikTok has different needs from a 30-second product shot. Try two or three models on your own prompt inside VIBE, keep the winner, and publish. That test costs a few minutes and beats any ranking.
