Qwen-Image-Edit (2511) on 20 GB of VRAM
Not at full quality. The 16-bit and 8-bit files are too big for 20 GB; the largest that fits is Q6_K (16.9 GB). The editing version of Qwen-Image, release 2511. Same 20B size and the same text encoder as Qwen-Image.
Q6_K (16.9 GB) fits with only 0.1 GB to spare (about 19.9 GB of 20 GB). Quality: very close to the original.
Also try the FP8 file (20.5 GB) on NVIDIA GPUs. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →
