The Model
Meet HappyHorse-1.0
Elo 1333 T2V · Elo 1392 I2V · Both #1.
HappyHorse-1.0 debuted at #1. With no announcement, no named team, and no paper, it entered the Artificial Analysis Video Arena and within 48 hours accumulated the highest scores for both text-to-video and image-to-video generation.
Built on a 15-billion parameter Unified Self-Attention Transformer with no Cross-Attention, it processes text, images, video frames, and audio in a single token sequence — generating video and synchronized audio in one pass. The best AI video output in independent testing, validated by thousands of blind human preference votes.
Capabilities
What Makes HappyHorse-1.0 Different
Unified Architecture
One Transformer. Every Modality.
No seams. 40-layer Unified Self-Attention ingests text, image patches, video frames, and audio into a single token sequence. Temporal coherence and audio sync are architectural defaults — not add-ons.
8-Step CFG-Free Inference
Fast Without Compromise.
Diffusion models need 20–50 steps plus Classifier-Free Guidance. HappyHorse-1.0 needs 8 and zero CFG. A 10-second 1080p clip with synchronized audio generates in ~32 seconds.
Native Audio-Video Generation
Perfect Sync, One Pass.
Audio and video are generated simultaneously in the same forward pass — not stitched post-generation. Ambient sounds exist in the same representational space as the environment that produced them.
7-Language Lip Sync
One brief. Six campaigns.
Synchronized lip movement natively in Mandarin, Cantonese, English, Japanese, Korean, German, and French. No re-timing, no manual sync, no post-production lip dubbing workflow.
Multi-Shot Storytelling
~87% cross-clip consistency.
Generate a character in clip one; clip five maintains identity, wardrobe, and color palette — the highest of any model tested at equivalent speed. No complex reference injection.
Image-to-Video Reference Follow
Elo 1392 — market-leading I2V.
Source image fidelity through generated motion. Product shots retain lighting and material properties. Portraits maintain identity. A continuation of the image — not a reinterpretation.
Process
3 Steps to Cinematic Video
01
Describe or Upload
Type your prompt in English, Chinese, Japanese, Korean, German, or French — or upload a reference image. Describe the scene, motion, camera, and mood. The more specific, the better — but even a simple prompt produces leaderboard-quality results.
02
Set Your Parameters
Choose aspect ratio (16:9, 9:16, 1:1, 4:3, 3:4), duration (2–15 seconds), and resolution (720p free / 1080p paid). Add audio parameters for native audio-video generation, or select a language for lip-sync.
03
Generate and Download
HappyHorse-1.0 generates your video — with synchronized audio in one pass. Preview, then download at full quality. No watermarks on paid plans. MP4, ready for any platform or post-production workflow.
Use Cases
What You Can Create
Social Media Content
Vertical video for TikTok, Instagram Reels, and YouTube Shorts at 30 FPS. Audio that matches your soundtrack. With 7-language lip sync, one brief becomes six localized campaigns without additional production steps.
Product Demo Videos
Transform product photography into animated demos using HappyHorse-1.0's market-leading I2V capability. Source image fidelity — color, material, composition — outperforms every comparative model in independent testing.
Brand & Marketing Video
Multi-shot brand videos with consistent character appearance, style, and color palette across clips. Native audio-video generation means music-driven brand content is produced end-to-end in a single workflow.
