This r/StableDiffusion thread addresses performance issues with the Qwen-Image-Edit-2511 FP8 mixed model in ComfyUI, where users experience slow image edit times of 30–40 seconds per step (or overall), and seek GGUF quantization alternatives. The Qwen-Image-Edit-2511 model is approximately 40GB in size, making it slow to run without hardware-appropriate quantization. For users with limited VRAM, GGUF variants are recommended, loaded via the ComfyUI-GGUF custom node by city96. Unsloth provides GGUF-quantized versions of Qwen-Image-Edit-2511 using their Dynamic 2.0 methodology, which upcasts important layers to higher precision for improved accuracy.
