HappyHorse-1.0 is a unified multimodal AI video generation model that climbed to the top of the Artificial Analysis Video Arena blind-test leaderboard for both text-to-video and image-to-video generation. CNBC Alibaba Group confirmed ownership of HappyHorse, developed under its Alibaba Token Hub (ATH) business unit, where it leads benchmarks outperforming ByteDance's Seedance 2.0 and others. Caixin Global Led by Zhang Di — the former VP of Kuaishou who architected Kling AI — the 15-billion parameter model generates 1080p video with synchronized audio in a single pass using a unified transformer architecture that bypasses the multi-stage pipelines used by every major competitor.

ingle self-attention architecture with modality-specific projections in the first/last 4 layers and shared parameters across the middle 32 layers for seamless multimodal generation.
Ranked #1 in both Text-to-Video (Elo 1333) and Image-to-Video (Elo 1392) on Artificial Analysis Video Arena, surpassing Dreamina Seedance 2.0 by 60 and 37 points respectively.
Native support for six languages (Chinese, English, Japanese, Korean, German, French) with claimed ultra-low WER lip-synchronization.
Generates dialogue, ambient sounds, and Foley effects alongside video in a single pass through unified token denoising—no separate audio pipeline required.
One unified model handles both text-to-video and image-to-video tasks, appearing under the same model name in both arena categories.
Self-reported speeds of ~2 seconds for 5-second clips at 256p and ~38 seconds at 1080p on H100 hardware (unverified by third parties).

HappyHorse-1.0 won 80% of head-to-head matchups against Ovi 1.1 and nearly 61% against LTX 2.3 in blind user tests, with Visual Quality scoring 4.80 and Physical Consistency reaching 4.52. CTOL Digital Solutions Results are based on thousands of blind human-preference evaluations on the Artificial Analysis Video Arena.
Native lip-sync across 7 languages — Mandarin, Cantonese, English, Japanese, Korean, German, and French — producing dialogue, ambient sound, and Foley effects alongside video without a separate audio pipeline.
A single 40-layer self-attention Transformer processes text, image, video, and audio tokens in one unified sequence — with modality-specific layers at start and end, and 32 shared-parameter layers in the middle enabling seamless multimodal fusion.
In Image-to-Video without audio, HappyHorse-1.0 leads with an Elo of 1402, with Seedance 2.0 at 1355 and Grok Imagine Video at 1331 WaveSpeedAI — reflecting consistent user preference in blind head-to-head comparisons.
The HappyHorse-1.0 API transforms static photographs into animated sequences — maintaining visual fidelity while introducing natural movement and claimed synchronized audio.
Claimed specs include 15 billion parameters, a unified 40-layer self-attention Transformer, DMD-2 distillation to 8 denoising steps, and roughly 38 seconds for Ultra HD on a single H100. Cutout.Pro These figures are self-reported and have not been independently verified.

As of April 2026, HappyHorse-1.0 is not publicly accessible. There is no public API, no downloadable weights, no documented pricing, and no SLA. The model exists as a leaderboard entry with verified quality signals from blind user votes, but practical access does not exist yet. Watch for GitHub repository releases, HuggingFace model cards, or API announcements to know when it becomes available.
The documentation describes base model, distilled model, super-resolution module, and inference code as released with commercial usage rights — but the GitHub README includes a warning that model weights and inference code are marked "coming soon." Documentation says released; download links say not yet. Cutout.Pro Treat open-source claims as pending verification until weights are publicly accessible.
The model claims Ultra HD output in approximately 38 seconds on a single H100 GPU, using 8-step denoising inference with no CFG required. OpenPR These figures are self-reported by the development team and have not been independently verified.
