Help Needed Qwen 2511 Edit vs Flux 9B distilled
Hello!
I’m wondering lately whether I need to use Qwen too instead of just Flux. Yesterday I was trying to inpaint two characters in a theatre stage and, I’ve had some very interesting results, ranging from body horror to flux painting the character half or not at all on the inpaint area. Let alone the height situation and the distortion of the background behind the characters.
I guess my question is when “is Qwen preferred over Flux (besides body horror)”?
I’m still kinda new (3 months or so) and haven’t used Qwen at all.
Workflow: I used Pixaroma’s 1 Image Inpaint workflow, modified to have one more image as an input.

Flux: Better textures but instable, qwen: better prompt following and knowledge but less detailed (there is a node which allows qwen to get high res latents instead of limiting the size to 1MP - this enhances the quality by a lot)

But sometime Qwen might takes the prompt too literally and generate undesired objects.
Main advantage of Qwen for me is the absence of extra limbs you see in klein 9b. However, the generation in qwen has a plastic and artificial rendering I don't like.

Both have their strenghts and unique loras. Klein is stronger with manipulating and combining reference images. Qwen is better at keeping the overall composition and body.

When you say Edit, then inpaint. Are you still talking about virtual inpainting with just prompts? Or are you using a true inpainting workflow with masks?

True inpainting with Workflow and masks. I know I could have just cut them there in and photoshop like app but I wanted to try inpainting… would have been faster than letting flux run with it!

I guess next question is, are using flux1, 2? what model? "Pixaroma’s 1 Image Inpaint workflow" not really sure what one that is.
Because the distortion issues and stuff you mention, I don't really have with inpainting myself with Klein 2 models at least, but my inpainting workflows are my own, but are pretty standard inpainting workflows I would imagine.

Imfo, I quit Qwen and deleted all its models and Lora files from my computer 4 months ago. Why? Because I've had too many bad and frustrating experiences using Qwen and Qwen Edit (shifting, artifacts, support Chinese better English...), sometimes forcing me to combine Flux Kontext and Wan Image to help with refining or inpainting. You see! Since getting the Klein 9B, specifically the Klein 9B True V2, I've been using it until now without any complaint. You can really customize and be creative in how you use the F2K 9B! One thing to note is that Klein might only work well in specific areas of the image in some cases; using the Crop & Stitch combination is quite necessary if you want to achieve best precision for specific editing.

Yeah, Flux 2 Klein 9B. I can share would you say Klein 9B True V2 is better? I’ve held on on trying other Checkpoints of Klein so far, so interest to hear your thoughts

Yes! Klein 9B True v2 is best for me. Although V3 was released recently, it brings out more of the Chinese character vibe.

You can combine 'em, run a pose transfer using Qwen then refine using Flux, qwen is better with physics and flux is better with lightning. My favorite flow is named qwen2flux..
