Wan2.1 - An open-source video generation model developed by Alibaba's Tongyi Lab.
## Definition of Wan2.1
**Wan2.1** is an open-source video generation model developed by Alibaba's Tongyi Lab. It enables users to create 5-second dynamic videos from text prompts or uploaded images, with additional features like prompt optimization and audio generation. The model is accessible via the web platform [wan.video](https://wan.video/) or as a downloadable open-source project on [GitHub](https://github.com/Wan-Video/Wan2.1).
## Functionalities of Wan2.1
Wan2.1 supports the following core functionalities:
- **Text-to-Video**: Generates 5-second videos (480P or 720P) from text descriptions.
- **Image-to-Video**: Converts uploaded images into videos.
- **Video Editing**: Modifies existing videos.
- **Text-to-Image**: Generates static images from text.
- **Video-to-Audio**: Adds audio to generated videos.
Additional tools include **prompt optimization**, **inspiration mode**, and a **point system** to incentivize user activity.
## Point System on wan.video
The **point system** on [wan.video](https://wan.video/) operates as follows:
- **Earning Points**:
- Daily check-in: 50 points.
- Liking content: 10 points.
- Publishing work: 40 points.
- **Spending Points**:
- Each video generation costs 10 points.
This gamified design encourages regular platform engagement.
## Hardware Requirements for Wan2.1
To run Wan2.1's **T2V-1.3B model** locally:
- **VRAM**: Minimum 8.19 GB (e.g., NVIDIA RTX 4090).
- **Generation Time**: ~4 minutes for a 5-second 480P video.
Higher-end models like **T2V-14B** require more resources; details are unspecified.
## Access Points for Wan2.1
Users can access Wan2.1 through:
1. **Web Platform**: [wan.video](https://wan.video/) for no-code video generation.
2. **Open-Source Model**:
- GitHub: [Wan-Video/Wan2.1](https://github.com/Wan-Video/Wan2.1).
- Model Hosts: [Hugging Face](https://huggingface.co/Wan-AI/) or [ModelScope](https://modelscope.cn/organization/Wan-AI).
3. **Third-Party Integrations**: Platforms like [Monica AI](https://monica.im/en/ai-models/wan) and [fal.ai](https://fal.ai/models/fal-ai/wan-t2v) offer limited试用.
## Unique Features of Wan2.1
Wan2.1 stands out due to:
- **Wan-VAE Technology**: Encodes/decodes infinite-length 1080P videos while preserving temporal data.
- **Multilingual Text Support**: Generates videos with embedded Chinese/English text.
- **Scalability**: Models range from 1.3B to 14B parameters, balancing quality and hardware demands.
- **Social Integration**: Unique point system fosters community interaction.
## Limitations of Wan2.1
Potential limitations include:
- **Hardware Dependency**: Local operation requires high-end GPUs.
- **Resolution Trade-offs**: 720P output may be less stable than 480P.
- **Point System Clarity**: Unclear if points have caps or alternate uses beyond video generation.
- **Platform Accessibility**: [wan.video](https://wan.video/) may have regional restrictions.
