Happy-Horse. A new model that ranks above Seedance 2.0 on Artificial Analysis (more examples below)
One Model. Text, Video & Audio — Unified.
Single-Stream Architecture
40-layer Transformer processes text, video, and audio via self-attention only. No cross-attention, no separate encoders — one unified stream that jointly denoises all modalities.
Human-Centric Quality
Expressive facial performance, natural speech coordination, realistic body motion, and accurate lip sync. Purpose-built for human-centric video generation at the highest fidelity.
Blazing Fast Inference
5-second 256p video in just 2 seconds. 5-second 1080p in 38 seconds on a single H100 — powered by DMD-2 distillation with only 8 denoising steps and no quality loss.
State-of-the-Art Results
80.0% win rate vs Ovi 1.1 and 60.9% vs LTX 2.3 across 2,000 human evaluations. Leads on visual quality, text alignment, and word error rate benchmarks.
Multilingual
Natively supports 6 languages: Chinese, English, Japanese, Korean, German, and French. Multilingual prompts work out of the box with no translation layer.
Fully Open Source
Base model, distilled model, super-resolution model, and inference code — all publicly released. No API gatekeeping, no waitlist.
