   HappyHorse 1.0

   It appeared without a name on the Artificial Analysis video arena in early April and led several of its blind-vote rankings for text-to-video and image-to-video. A few days later Alibaba confirmed its ATH unit had built it. It generated picture and sound together, from text or a single start image.

   HappyHorse 1.1

   Added a reference mode that keeps the subjects from up to 9 photos consistent in one clip, along with smoother, more expressive motion and steadier detail from frame to frame. Clips run 3 to 15 seconds with sound built in.

1. 01

   Write the prompt first

   Happy Horse AI, as many people write it, always needs written directions, even when you add a photo, so describe the action, the setting and what we should hear.
2. 02

   Choose a start frame or a reference set

   In the mode menu, Standard takes one picture for the clip to open on, or none at all; Reference takes up to 9 photos of people, pets or objects to bring together. One run uses one mode.
3. 03

   Set length and resolution

   Clips run 3 to 15 seconds at either of two resolutions. With a start frame, the video keeps your picture's proportions.
4. 04

   Generate and pick a favorite

   The Generate button shows the cost, and the finished clip plays in My creations. Remake reloads your photos, prompt and settings when you want a variation.

• Side by side with other video models

  It sits in the same menu as Kling, Seedance and Hailuo AI, so you can test one prompt on several and keep the clip that moves the way you pictured.

• Nine photos in one scene

  Reference mode helps when the people or things in your video come from different pictures, like a friend, a pet and a favorite jacket.

• Sound without extra steps

  Every clip arrives with audio, so there's no separate sound tool to open before you share it.

• A clear price before you start

  The credit figure on the Generate button changes with length and resolution, and reference photos don't add to it. A run that fails gives the credits back.

• Ready to post or sell

  Videos made with an active membership come without a watermark and can be used commercially, from shop listings to client work.

• Your photos stay out of training

  Plimo doesn't use the portraits, pets or products you upload, or the clips made from them, to train any model.

• Kling

  Kling 4.0 offers start and end frames and stretches to 30 seconds; HappyHorse 1.1 takes a start frame but no end frame and tops out at 15 seconds.

• Veo

  Veo 3.1 Fast always makes 8 seconds and takes up to 3 reference photos, where you can set the length here and use up to 9.

• Seedance

  Seedance pairs reference photos with reference clips and has a sound switch; its 2.0 Mini version runs on free credits.

• Hailuo AI

  Hailuo AI's MiniMax H3 Max shares the 9-photo reference limit and always-on sound, adds end frames and reference clips, and focuses on lifelike faces.

• Grok Imagine

  Grok Imagine 1.5 takes up to 7 reference photos but has no start frame slot, runs 6 to 15 seconds, and new accounts can make a short clip with it on free credits.

• Wan

  Wan 3.0, a sibling from Alibaba, runs as long as 30 seconds, accepts an end frame and reference clips, and has an audio switch.

• Vidu

  Vidu Q4 Preview takes up to 15 reference photos and can animate a start frame with an empty prompt box.

• FLUX

  FLUX 3 Video has no reference photos but supports an end frame and clips of up to 20 seconds.

• SkyReels

  SkyReels V4 keeps sound on too, and swaps the 9-photo reference mode for 3 photos or a start-and-end-frame pair.

• Friends who live far apart

  Add a portrait of you and one of a friend who moved abroad, and describe the two of you clinking glasses at a rooftop bar while the city hums below.

• A pet and its favorite toy

  Use one photo of your cat and one of its battered toy mouse, and ask for a dramatic slow-motion pounce across the living room rug.

• An old family photo that turns to smile

  Set a scanned family photo as the start frame and describe everyone turning toward the camera, with birdsong and distant traffic in the audio.

• An outfit check

  Combine a full-length photo of yourself with photos of a jacket and a pair of boots, and describe walking toward the camera on a busy street wearing them.

• A small product ad

  Put photos of a candle, its box and a sprig of lavender in reference mode and ask for a cozy close-up as a match is struck. Made during a membership, it can go in a shop listing.

• A drawing that flies away

  Use a child's crayon dragon as the start frame and describe it flapping off the page while the paper rustles and a small voice cheers.

• A holiday greeting

  Describe a snowy cabin, a dog in a red scarf and a warm voice saying happy holidays from all of us, then send it instead of a card.

• A team photo that cheers

  Set a group shot from your club or office as the start frame and describe everyone throwing their arms up as a crowd roars and a whistle blows. It makes a fun end-of-season post.
