Happy Horse pro - AI video and audio generator
Happy Horse is an AI video generation studio built around a unified 15-billion-parameter Transformer architecture. Designed to handle multimodal tasks in a single forward pass, the platform combines text-to-video, image-to-video, and native audio co-generation into one workspace. It is built to produce cinematic visual motion and synchronous audio tracks directly from text prompts or reference assets without requiring separate editing pipelines.
- Unified Audio Generation: Co-generates video and synchronized audio including dialogue, ambient sound, and Foley effects in a single pass.
- Phoneme-Level Lip Sync: Supports accurate character lip synchronization across seven languages including English, Mandarin, and Japanese.
- Physics-Accurate Motion: Models realistic weight distribution, fluid displacement, and cloth drag for natural visual movement.
- Multi-Engine Workspace: Integrates alternative image and video engines like Kling, Veo, Flux, and Seedream alongside the core model.
- Commercial Licensing: Delivers production-ready, watermark-free outputs suitable for advertising, social content, and client work.
The platform caters to creators, developers, and product builders seeking high-fidelity AI media generation tools without managing local GPU hardware. Available via web browser with flexible tier structures including starter access and professional plans.
