Sample Video

Most video models generate pictures first and bolt on sound later. HappyHorse 1.0 encodes text, video, and audio in one stream — so a door click, a rainstorm, and a spoken line belong to the same moment.
Why HappyHorse 1.0 stands out
One pass for picture and sound
A 15B transformer attends to text, video, and audio together. Lip motion and speech are created together at phoneme level — not stitched after the fact.
Subject identity that holds
Faces, wardrobe, and products stay consistent across motion. Reference-to-video can lock up to nine visual anchors so a character or SKU does not drift mid-clip.
Directorial prompt language
Describe shot size, camera moves, timing, and sound design. HappyHorse 1.0 treats “slow push over three seconds, warm window light” as structure, not mood.
Proven in blind comparisons
On Artificial Analysis Video Arena, HappyHorse 1.0 ranked among the top video models in both text-to-video and image-to-video — judged by people who could not see the model name.
HappyHorse 1.0 is a family of video workflows on the same backbone. Pick the entry point that matches the assets you already have.
Four ways to generate
Built for people who ship short-form video — not just experiment with it. Human-centric performance is the focus: faces, speech, and products that have to hold up on a timeline.
Who HappyHorse 1.0 is for
Brand and campaign teams
Turn a hero still into motion, then keep the same talent or product consistent across variants. Fast enough for concept rounds, sharp enough for paid placements.
E-commerce and product video
Animate catalog photos, lock SKU appearance with references, and add ambient or voiceover-ready audio in the same generation.
From prompt to playable clip
HappyHorse 1.0 outputs up to 1080p, 3–15 seconds, in 16:9, 9:16, 1:1, 4:3, and 3:4. Generate on this page — no separate audio tool required.
One 15-billion-parameter system powers every workflow. Visuals and audio are generated together, with human subjects as the primary design target.
HappyHorse 1.0 capabilities
Joint video and audio generation
Picture, motion, speech, and ambience come from the same forward pass. A closing door and its click are one decision, not two pipelines.
Phoneme-level lip-sync
Mouth shapes follow speech sounds, not just words. Strong on talking-head and presenter clips across six languages.
Image-to-video first-frame lock
Your still becomes the exact opening frame. Motion continues with weight, eye-lines, and product geometry that stay believable.
Multi-reference identity control
Up to nine references can pin characters, outfits, and products so a series of clips stay visually aligned.
Shot-aware prompting
Wide opens, timed pushes, and sound notes are interpreted as shot structure — closer to a director’s brief than a generic mood prompt.
Production-ready output sizes
720p or 1080p, 3–15 seconds, landscape and portrait ratios for feeds, stories, and hero placements.
Four workflows, one architecture. Choose how you enter the generation — text, a still, references, or an existing clip intent.
The HappyHorse 1.0 family
