HappyHorse 1.1 generates picture and sound together, including dialogue with lip-sync, in clips of up to 15 seconds. On DreamBench it can make every scene of your video, and you can redo any scene without starting over.

**What HappyHorse 1.1 is.** HappyHorse 1.1, also written Happy Horse 1.1, is a video model from Alibaba, released in June 2026 as the upgrade to HappyHorse 1.0, which launched in April. It makes clips of up to 15 seconds and generates sound in step with the picture. Alibaba introduced HappyHorse with lip-synced dialogue, ambient sound and expressive vocal performances built in. For 1.1 it smoothed movement in complex action, improved how closely the model follows instructions and added richer, more lifelike detail, and it says sound and picture stay precisely in sync. Since the first version, Alibaba says, HappyHorse has been used for short-form dramas, e-commerce ads, brand marketing and cinematic game trailers.

**What HappyHorse 1.1 is good at.**
- People who talk to camera: Characters speak their lines with lip-sync, and the ambient sound and vocal performance are generated along with the picture.
- Smoother action: Alibaba reworked how 1.1 models motion over time, so complex action sequences move more smoothly and hold together.
- A cinematic look: Alibaba built HappyHorse for film-style images, with shallow depth of field, an atmospheric mood and fine texture, and 1.1 adds richer detail.
- Closer to your direction: Version 1.1 follows instructions more closely than 1.0, so more of what your prompt asks for makes it onto the screen.

**HappyHorse 1.1 on DreamBench.**
- HappyHorse 1.1 starts each clip from a single opening frame, which DreamBench makes from your reference images or the characters, props and places it designs for you. It can’t be given a final frame to end on, so the prompt steers how each clip finishes.
- Each clip runs up to 15 seconds and doesn’t cut to a new setting partway through, so a longer video joins several clips. Keep each spoken line short enough to finish inside its clip.
- Alibaba’s own tools also offer a reference-to-video mode that builds a clip around several images of a product, character or place. On DreamBench, HappyHorse 1.1 animates each clip from its opening frame, and you change a scene by giving it new direction.

**Prompt ideas.**
- The baker’s secret: Vertical 9:16, filmed like a phone video. A cheerful baker in a flour-dusted apron leans toward the camera in her tiny shop kitchen and says, “Here’s the secret: cold butter, warm hands, and never rush the dough.” She laughs, slides a tray of golden croissants onto the counter and winks. The hum of the oven, a ticking timer, pastry crackling as it cools.
- Truth on the rooftop: Cinematic 21:9, a rain-soaked rooftop at night. A detective in a long coat faces the colleague who betrayed her under a flickering sign. She says quietly, “You had one chance to tell me the truth.” He looks away: “I was protecting you.” Shallow depth of field, rain streaking through the light, distant sirens and a low roll of thunder.
- A quick product demo: Square 1:1 video for a feed ad. In a bright bathroom, a young man holds a plain white tube of hand cream up to the camera, squeezes a little onto his palm and rubs it in. He smiles and says, “Soaks in fast, no greasy hands, and it smells like clean laundry.” Soft window light, the click of the cap, a faucet running gently.

**HappyHorse 1.1 FAQ.**
- **What is HappyHorse 1.1?** HappyHorse 1.1 is a video model from Alibaba, released in June 2026 as the upgrade to HappyHorse 1.0. It generates picture and sound together, including dialogue with lip-sync, in clips of up to 15 seconds.
- **What’s the difference between HappyHorse 1.1 and 1.0?** HappyHorse 1.1, released by Alibaba in June 2026, moves more smoothly in complex action, follows instructions more closely, adds richer detail and keeps sound and picture in tighter sync than HappyHorse 1.0 from April 2026. It also reads several reference images better, a mode DreamBench doesn’t use. DreamBench runs 1.1.
- **Can HappyHorse 1.1 make people talk to camera?** Yes. HappyHorse 1.1 generates dialogue with lip-sync as part of the clip, along with ambient sound and the voice’s performance, so a presenter, a vlogger or a character in a drama can speak straight to camera. On DreamBench, write the line in quotation marks, say who speaks it, and keep it short enough to finish inside a 15-second clip: a line that runs past the clip’s end gets cut or hurried, so give that scene new direction if the lip-sync misses.
- **How long can a HappyHorse 1.1 video be on DreamBench?** Each clip HappyHorse 1.1 generates runs up to 15 seconds. A whole DreamBench video can be longer, up to 5 minutes depending on your plan, because DreamBench plans the scenes and joins the clips into one video.
- **What resolution does HappyHorse 1.1 use on DreamBench?** HappyHorse 1.1 renders at 720p or 1080p on DreamBench, your choice. You can make it square (1:1), widescreen (16:9), portrait (9:16), 4:3 or cinematic 21:9.
- **Does HappyHorse 1.1 make sound?** Yes. On DreamBench every HappyHorse 1.1 clip comes with sound generated together with the picture, from dialogue to ambient noise, so describe what should be heard as well as what should be seen.

Every clip comes with sound, and the composer shows the exact cost before you generate.
- **What should a HappyHorse 1.1 prompt say?** Say who speaks, put the words in quotation marks, then describe the setting, light and camera. Keep each clip to one setting: HappyHorse 1.1 doesn’t cut partway through a clip, so a longer video joins several clips.
- **Can I use reference images with HappyHorse 1.1 on DreamBench?** Yes, up to 8 per video. DreamBench turns them into each clip’s opening frame, which HappyHorse 1.1 animates. Alibaba’s multi-image reference-to-video mode is not what DreamBench runs.
