HappyHorse 1.0 is Alibaba Cloud Model Studio's video generation model family. One HappyHorse 1.0 prompt yields a 3-15 second 1080P clip from text, a first-frame image, up to 9 reference images, or an existing video. Cinematic dialogue, ambient soundscapes, and FPV one-takes all came out of the HappyHorse 1.0 launch.
Alibaba Cloud Model Studio's video model with four input modes
HappyHorse 1.0 is Alibaba Cloud Model Studio's (ιΏιδΊηΎηΌ) video generation model. Four variants β text-to-video, first-frame I2V, reference-to-video, and video-edit β share one Bailian DashScope endpoint. Each HappyHorse 1.0 render outputs a 3-15 second 720P or 1080P MP4 clip.
HappyHorse 1.0 covers T2V, I2V (first-frame), Reference (1-9 character images), and Video-Edit β one Bailian endpoint, one billing grid.
Every HappyHorse 1.0 variant accepts duration 3-15 seconds (default 5). Pick short for loops, long for openers.
HappyHorse 1.0 outputs MP4 H.264 at 720P or 1080P, defaulting to 1080P. Works for social, web, and most ad formats.
T2V and Reference HappyHorse 1.0 variants take 16:9, 9:16, 1:1, 4:3, and 3:4 β Reels, YouTube, feeds, all in one prompt.
The Reference HappyHorse 1.0 variant accepts 1 to 9 reference images, addressed in prompt as `character1`...`character9`.
Authenticate with a DashScope API key, POST to the Bailian video-synthesis endpoint with `X-DashScope-Async: enable`, poll the task to a 1080P MP4.
The HappyHorse 1.0 launch reel rendered English, Mandarin, regional dialect, and code-mixed lines inside the clip.
The HappyHorse 1.0 launch reel demonstrated character dialogue rendered alongside the video β a noir English cafΓ© exchange, a Mandarin interrogation room beat, a Shaw Brothers language-swap comedy, a Henan-dialect product gag, and a bilingual private-jet negotiation. Among the four documented variants, only the HappyHorse 1.0 video-edit variant exposes an explicit `audio_setting` parameter in the API; the launch demos for the other variants nevertheless ship clips with audio. Treat the reel as the spec for what the family can sound like.
HappyHorse 1.0 accepts up to 5,000 non-Chinese (or 2,500 Chinese) characters per prompt β extended scripted scenes survive.
Earlier video models gave up after a couple sentences β the camera lost the brief by beat three. HappyHorse 1.0 carries a long shot-list prompt across the clip: an FPV launch from ground level, a Bagel-store slow-mo deceleration, a vertical climb past skyscraper glass, an axial flip, a MΓΆbius mirror-world finale. The launch reel ran an 800-character storyboard prompt through a single HappyHorse 1.0 render β the camera moves landed in order.
The HappyHorse 1.0 I2V variant takes exactly one first-frame image and animates from there.
Hand HappyHorse 1.0 a single image β JPEG, JPG, PNG, or WEBP, each side at least 300 px, aspect ratio between 1:2.5 and 2.5:1, file size under 10 MB β and the I2V variant treats it as the literal first frame of the clip. Style transitions are in-domain: the launch reel showed a cartoon character spinning once and resolving into a photoreal scene mid-render. Useful for openers, product reveals, and story-driven I2V where the still already exists.
HappyHorse 1.0 launch clips ship ambient SFX β leaves, wind, water, room tone β alongside the frames.
Walking-on-leaves, wind-through-canopy, distant-stream β the HappyHorse 1.0 forest-path launch demo delivered all of it inside the clip. Ambient soundscape is not a documented HappyHorse 1.0 API parameter for T2V/I2V/Reference, but the launch reel makes the capability observable. ASMR cuts, location B-roll, and atmospheric inserts post directly without a separate sound-design pass.
The HappyHorse 1.0 Reference variant accepts 1-9 character images and binds them to `character1`...`character9` in your prompt.
Two characters that need to stay the same person across a beat β a boy and a rusty robot whispering 'we are friends', then a wide pull-back β that's the failure mode where weaker models drift. HappyHorse 1.0's Reference variant accepts up to 9 reference_image entries (each at 720P+, under 10 MB, aspect 1:2.5 to 2.5:1) and binds them to character tokens in the prompt. A HappyHorse 1.0 Reference clip can hold identity, wardrobe, and prop continuity through the cut.
Ten clips β each caption is a real HappyHorse 1.0 prompt from the public launch

Four habits that get a usable HappyHorse 1.0 clip on the first render
Decide between `happyhorse-1.0-t2v` (text only), `happyhorse-1.0-i2v` (one first-frame image), `happyhorse-1.0-r2v` (1-9 character references), and `happyhorse-1.0-video-edit` (an existing clip plus optional refs). Each variant takes a slightly different brief β and the right pick saves a reroll.
HappyHorse 1.0 takes `duration` 3-15s, `resolution` 720P or 1080P, and `ratio` from 16:9, 9:16, 1:1, 4:3, 3:4 (T2V and Reference only). Pick before you write β 9:16 5s for Reels, 16:9 12s for an opener β so the prompt aims at a concrete frame.
HappyHorse 1.0 holds long prompts (up to 5,000 non-Chinese / 2,500 Chinese characters). Name the subject, the camera move, the lens, the lighting, and what you want to hear. The launch reel demonstrates the model rendering audio alongside the frames β describe it explicitly.
If you're on the HappyHorse 1.0 Reference variant, drop reference images into `media[]` and call them out as `character1`, `character2`, ... in the prompt. Each reference image must be JPEG/JPG/PNG/WEBP, short side β₯ 400 px, file size β€ 10 MB.
Each video model has its own strengths β realism, speed, style, cost
