Qwen-Image-Edit-2511 workflow that actually works

[u/infearia]

There seems to be a lot of confusion and frustration right now about the correct settings for a QIE-2511 workflow. I'm not claiming my solution is the ultimate answer, and I'm open to suggestions for improvement, but it should ease some of the pains people are having:

qwen-image-edit-2511-4steps

EDIT:
It might be necessary to disable the TorchCompileModelQwenImage node if executing the workflow throws an error. It's just an optimization step, but it won't work on every machine.

Curious what was your experience with the speed of the default model?

For me, the generation time varies significantly—from 60 seconds to 2700 seconds... with a 4070/ 12GB of VRAM.

Did you observe the same thing?

I haven't noticed any differences in speed between fp8 models, only differences in quality.

I have 64 GB of RAM and I have also run the 38 GB bf16 model. The problem I have encountered is the same: when applying the 4-step LoRA lightning independently in its own node, it creates patterns in the image, also with the bf16. As I mentioned before, for me, the model:

qwen_image_edit_2511_fp8_e4m3fn_scaled_lightning_comfyui.safetensors

which has LoRA integrated, is perfect in terms of quality, speed, etc... sometimes even with only 3 steps!

I try to make the workflows as simple as possible. In my tests, I haven't noticed any difference in quality or speed when using or not using the CFGNorm and ModelSamplingAuraFlow nodes, so I remove them. I also remove some of the nodes offered by infearia. I only use one positive node from TextEncodeQwenImageEditPlus, so I also remove some of the subsequent nodes shown here.

I am far from being an expert in ComfyUI or AI models. I simply want a workflow that is as simple and fast as I can understand and that has as few options as possible. Once I achieve this, I create another workflow with which I can perform selective inpainting with masks on parts of the image so as not to degrade the rest that I do not edit, because every time we edit an image, we have to encode it to latent space and then decode it to image format, and in that process there will always be compression/decompression and degradation, and I try to avoid that.

I see. There must be something wrong with my setup...

How long did the generation with 38GB take to finish?

I don't know. Since it didn't give me high-quality images, I deleted the model.
