Technical Architecture

Developed and released in early 2026, Happy Horse 1.0 is built around a 40-layer self-attention Transformer architecture.

It is fully open source under commercial-use licensing. The release includes the base model, the 8-step distilled model, our proprietary super-resolution module, and optimized inference code — ready for native on-premise infrastructure.

40-Layer Core

Core Capabilities

Unified Transformer

40-layer self-attention network with robust single-stream processing and per-head gating for high-stability training scaling.

Joint Video & Audio

Generates synchronized dialogue, ambient sound, and Foley natively alongside video frames without a secondary post-production pass.

8-Step DMD-2 Distillation

Radically reduces denoising steps without CFG and uses the MagiCompiler runtime for much faster generation.

Multilingual Lip-Sync

Native support for 7 languages (EN, ZH, JP, KO, DE, FR) with strong prompt alignment and speech-to-motion consistency.

1080p Resolution Target

5–8 second pristine clips upscaled to 1080p across standard social aspect ratios.

Self-Hostable First

A permissive open-source model designed for in-house deployment with privacy-minded workflows.
