Wan

What Wan is
Wan is an open suite of video foundation models for generating and editing media. It supports text-to-video and image-to-video, as well as video editing, text-to-image, and video-to-audio tasks. The models can place Chinese or English text inside generated videos. For video editing and generation, VACE can take a prompt and optional video, mask, and image inputs. Wan-VAE handles encoding and decoding 1080P video of any length while preserving temporal information.
Wan runs on Linux and can be self-hosted. The T2V-14B model supports 480P and 720P output; T2V-1.3B supports 480P, and its 720P results are described as less stable. The T2V-1.3B model requires 8.19 GB of VRAM. The project reports about four minutes to generate a five-second 480P video on an RTX 4090 without quantization. Model downloads are available through Hugging Face and ModelScope. Installation guidance covers pip and Poetry, with PyTorch 2.4.0 or later required by the quickstart. The repository includes command-line and local Gradio inference examples. Wan is free and open source under Apache-2.0, and commercial use is permitted. Integrations include Diffusers and ComfyUI; prompt extension can use the DashScope API or a local Qwen model.
Who it suits
Wan suits creators and developers who want to run video generation models on Linux or self-host them. It is also relevant to users who need several media-generation tasks, including video editing and text rendered within video, and have the required GPU resources.
What it does well
- Supports text-to-video, image-to-video, editing, text-to-image, and video-to-audio.
- Can generate Chinese and English text within videos.
- T2V-14B supports output up to 720P.
- Open source under Apache-2.0; commercial use is permitted.
- Integrates with Diffusers and ComfyUI.
What to know first
- T2V-1.3B requires 8.19 GB of VRAM.
- T2V-1.3B supports 480P; its 720P results are less stable.
- The quickstart requires PyTorch 2.4.0 or later.
Limits
The T2V-1.3B model supports 480P, and its 720P results are less stable. The T2V-14B model supports 480P and 720P.
Getting started
- Open the Wan2.1 GitHub repository.
- Download model weights through Hugging Face or ModelScope.
- Use the installation guide's pip or Poetry method, with PyTorch 2.4.0 or later.
- Run inference from the command line or start the local Gradio interface.
- Use a local Qwen model or the DashScope API for prompt extension.
Verdict
Choose Wan if you want an open source, self-hosted video model suite with multiple generation and editing tasks, and can meet its setup and hardware requirements. Look elsewhere if you need a hosted service or higher resolution from the T2V-1.3B model.
