Happy Horse AI is a free AI video generator based on the Happy Horse 1.0 model, with the official website at https://happyhorse-ai.co/。根据官方资料，其核心定位是“一个统一模型，文本、视频与音频协同生成”，强调快速、多语言与完全开源。
[Purpose] Happy Horse AI is mainly used to generate video content with native audio from text or image prompts, making it suitable for quickly producing multi-shot videos for social media, advertising, or presentation scenarios. The official description states that it can generate videos with director-level composition, lighting, and cinematic camera language control, without the need for post-production.
[Main Capabilities]
- Text-to-video: Describe a scene in natural language, and Happy Horse 1.0 jointly denoises text, video, and audio tokens in a single unified sequence to generate physically realistic multi-shot videos.
- Image-to-video: In addition to a text prompt, provide a reference image latent, and the model generates conditioned on both at the same time, preserving the subject's identity and visual style while adding smooth, physically accurate motion.
- Native audio and lip sync: Unlike multi-stream pipelines that generate audio separately, Happy Horse 1.0 jointly denoises video and audio in one unified process, automatically generating synchronized speech, spatial sound effects, and precise lip sync, so a complete audiovisual output is obtained in a single generation.
- Performance and open source: The official description states that Happy Horse 1.0 achieves SOTA inference speed for 5-second video generation on an H100 GPU; the model is fully open source, and you can browse the model library, clone the inference code, or run a live demo.
- Multilingual: It is designed to support multiple languages and is aimed at creators worldwide.
- Output specifications: A single run can generate multi-shot high-quality videos up to 15 seconds long, maintaining consistency in characters, lighting, and world-building aesthetics across scenes. The official website also mentions support for 1080p cinematic quality (from user review content).
[How to Use] The official three-step creation process is:
- Describe the vision: Write a clear prompt listing the subject, scene, mood, and action; a reference image can be added for style control.
- Generate and refine: Happy Horse AI generates a multi-shot sequence with dynamic camera movement, and users can adjust the composition or style until satisfied.
- Preview and download: Preview and download the high-definition output, suitable for social media, advertising, or presentation use. The official website also provides a prompt assistance tool, style and aspect ratio controls, generation history saving, unlimited downloads, and other features (depending on the subscription plan).
[Applicable Scenarios] Official user reviews mention that it can be used for professional social media content, advertising, presentations, and more. It is suitable for creators who need to quickly produce multi-shot videos with audio from text or images.

[Limitations and Information Not Provided] The official FAQ mentions questions about video duration, output resolution, multimodal input, prompt writing, commercial use, whether it is free, choosing between text-to-video and image-to-video, open source, supported languages, and other issues, but the materials only list the question titles and do not provide specific answers. Therefore, these details are not yet provided.
[Other] Happy Horse 1.0 is described as "a single self-attention Transformer," replacing the multi-stream complexity of older architectures. The official website displays data such as today's creator usage and today's generated video count, but the specific values are not provided. User reviews mention advantages such as motion synthesis, unified audio-video generation, consistency, speed, and complex camera motion control, which are subjective feedback.
