How "comfyui wan 2.1 video workflow" works in ComfyUI on Windows
Users searching for **comfyui wan 2.1 video workflow** want a straightforward, working setup on Windows without broken Python dependencies or wasted VRAM. Modern diffusion models (Flux.1, SDXL, Hunyuan Video, and Wan 2.1) scale across 8 GB to 24 GB Windows GPUs when you pair the right loader node with FP8 or GGUF quantization.
ComfyUI separates model loading (Load Checkpoint / GGUF Loader), text conditioning (CLIP Text Encode), denoising (KSampler), and pixel decoding (VAE Decode) into explicit nodes so you have full visibility into every step.
Step-by-step checklist
- Grab the latest Windows desktop or portable installer from /download and launch ComfyUI Studio.
- Place your `.safetensors` or `.gguf` weights into the matching subfolder under models/ (or link an existing folder via extra_model_paths.yaml).
- Open ComfyUI-Manager to install any missing custom nodes if you imported a community JSON or PNG workflow.
- If VRAM is 8 GB–12 GB, use FP8 or GGUF Q4 weights and enable `VAE Decode (Tiled)` before queuing your prompt.
