One Model. Text, Video and Audio — Unified.
Happy Horse AI is powered by Happy Horse 1.0 — a single self-attention Transformer that jointly generates video and audio from text, replacing the multi-stream complexity of older architectures. Blazing fast, multilingual, and fully open source. Whether you start from a text prompt or a reference image, Happy Horse AI delivers state-of-the-art results at record speeds.
Text to Video AI
Describe your scene in natural language — Happy Horse 1.0 jointly denoises text, video and audio tokens in a single unified sequence, producing physically realistic multi-shot videos with no post-production needed. Director-level control over composition, lighting and cinematic camera language.
Image to Video AI
Supply a reference image latent alongside your text prompt — Happy Horse 1.0 conditions generation on both simultaneously within the same unified token sequence, preserving subject identity and visual style while adding fluid, physically accurate motion.
Native Audio & Lip-Sync
Unlike multi-stream pipelines that generate audio separately, Happy Horse 1.0 jointly denoises video and audio in one unified pass — producing synchronized voices, spatial sound effects and precise lip-sync automatically. Complete audio-visual output in a single generation.
Blazing Fast & Open Source
Happy Horse 1.0 achieves SOTA inference speed on H100 GPUs for 5-second video generation — and everything is open. Explore the model hub, clone the inference code, or run the live demo. Multilingual by design, built for creators worldwide.
