WAN 2.1 Low VRAM Text To Image ComfyUI Workflow & One Click Installer

Generate high-resolution 1024 × 1024 images in under 30 seconds on just 6 GB VRAM using the WAN 2.1 video generation model.
 
WAN 2.1 in ComfyUI offers advanced text-to-image capabilities, enabling users to create high-quality images directly from text prompts. Although WAN 2.1 is best known for its text-to-video (T2V) and image-to-video (I2V) workflows, you can easily generate single-frame images by setting the frame count to one in the workflow. This method delivers the same cinematic, high-fidelity rendering that distinguishes WAN 2.1 video outputs, resulting in visually impressive still images.
 
I've developed a one-click installer and a custom workflow that lets you run WAN 2.1 diffusion models or quantized GGUF models for fast image generation—even on low VRAM devices. For users who want to run full-precision or fp8 WAN 2.1 models, my pre-made WAN 2.1 Runpod Template is also available. Simply launch the pod and upload the workflow provided below.
