qwen_image_2.1_Q8_0.gguf

The Q8_0 file of Qwen-Image 2.1. 7.6 GB on disk, about 9.9 GB of VRAM to run without offloading. In ComfyUI it goes in models/unet.

Where to put it

Put the file in ComfyUI/models/unet/ (portable version: ComfyUI_windows_portable/ComfyUI/models/unet/). Press R in ComfyUI or restart it, then pick the file in Unet Loader (GGUF) from the ComfyUI-GGUF custom nodes.

If a workflow says “Value not in list” for that node, the workflow expects a file with another name. Click the node and choose this one.

Need = file × 1 + 1.5 GB for the picture and 0.8 GB for Windows and the browser — the same rule as the rest of the site.

Time = sampling + VAE decode, after a warm-up run. Peak VRAM = memory in use on the whole card. How I measure.

Same model, different compression. 8-bit files (FP8, INT8, Q8_0) look almost the same as 16-bit; below Q5 the loss starts to show.
