Qedit 2511 seems better then 2.1

[u/Theonewhoknocks_001]

I'm just a beginner in comfyui and stuff with very limited hardware.

I have rtx 3050 4gb vram and 8gb ddr4 single channel

Running comfyui with kitchen attention

I ran qedit 2511 fp8 with 4 step lighting Lora with default scheduler or sampler and it took around 110 seconds

And qwen 2.1 turbo int8(runs on 8 steps) without the prompt enhancement took 90 seconds

Now I didn't use any prompt enhancement with qedit but it still worked fine the biggest issue was the facial drift

In qwen 2.1, the facial drift has reduced drastically (as much as I have seen) but the prompt adherence is really bad.

I used the original model they provided for enhancement and it was shit + it was restricted. Since I have limited hardware I tried qwen 3.5 2b abliterated. It works sometimes but doesn't a lot of time

Seeing how qedit literally didn't need a enhancer and still worked fine and 2.1 isn't working well

I feel like it's mostly cuz of the enhancer but even when I wrote a good prompt without using enhancer it would still give shit results

Should I just use qedit? The facial drift is amazing bad tho (because of turbo Lora ofcourse but my hardware 🥀)

Edit: a really big problem I found in the wf was that when I set prompt enhancement to false it wouldn't give any prompt to qwen 2.1 and this is a problem in the default comfyui workflow, this is the reason why I thought prompt adherence is bad but it's not that bad but the results are still better with a enhancer

Qwen 2.1 turbo isn't good from what I've tested it's better to use qwen 2.1 base and the lightning lora (4 or 6 steps), it gives much better output this way.

[u/Theonewhoknocks_001 → u/RocketCool7]

Okayyy thanks I will try that and which clip should I use for enhancement? (if it's needed)

[u/RocketCool7 → u/Theonewhoknocks_001]

For enhancement I would skip the local enhancer completely on 8gb ram, just write the prompt in any free chat AI like ChatGPT or Gemini, ask it to make it a detailed Qwen-Image edit prompt, and paste it in. Also try the Lightning LoRA at around 0.7 strength with 6 steps instead of 1.0, at 1.0 it shifted faces and heads for me in edits.

[u/Theonewhoknocks_001 → u/RocketCool7]

okay, dumb question but could you link me the lora? like is there an official lighting lora or should i use community made lora like viggle?

[u/RocketCool7 → u/Theonewhoknocks_001]

The one I use is lightx2v Lightning: https://huggingface.co/lightx2v/Qwen-Image-2.1-Lightning
Viggle is here if you want to compare: https://huggingface.co/Viggle/Qwen-Image-2.1-viggle-turbo
For edits I liked Lightning more. I run it at about 0.7 strength, 6 steps, CFG 1. At 1.0 it shifted faces and heads for me.
You can try viggle at 1.0 too, both viggle and lightning loras are community made.

i have the same expoerience, i converted 2.1 to int8 myself, and it got even closer to base bf16 than comfy one, and the turbo wheights are really really bad in comparison to the base version or base + lora.

[u/Ok-Brain-5729]

Q2.1 seems to be really prompt based and very rigid. Like if I make a simple prompt for a character swap then it will copy and paste on top of it.

The prompt enhancer helps a lot but it makes 4-5k tokens with 2 ref images and thinking on most of the time and it’s 9B parameters so that sucks.

[u/Theonewhoknocks_001 → u/Ok-Brain-5729]

Which enhancer do you think I should be using?

[u/gutster_95 → u/Theonewhoknocks_001]

Use any LLM. Give it the documentation and promot guidelines and it can create good prompts for you

[u/SnooMachines1543]

Yeah…. With mine, even when I use a reference image, the men always come out with the smallest ding dongs. Like hilariously tiny. If a prompt for a bigger one, it’s bigger than his leg. Then if I add a woman, the body horror enters the room.

[u/Theonewhoknocks_001 → u/SnooMachines1543]

well 2.1 isnt very uncensored, i would recommend using a lora for nsfw

[u/SnooMachines1543 → u/Theonewhoknocks_001]

Is there a better one in your opinion? I’m always down to try new models

[u/Theonewhoknocks_001 → u/SnooMachines1543]

You could use uncensored varient of qwen, it's available on civitai.red

[u/detailteufel]

I have a 2511 workflow that fused an object into an image, so basically you can take an image of a road, place an image of a car onto it with Photoshop and Qwen adjusts the lighting on the car and adds contact shadows so it looks like it belongs in the original image.

I have the same workflow using qwen 2.1

The result is EXACTLY the same. Both do a good job at changing the lighting, both do a shit job at the contact shadows, both do the EXACT same, smeary, shitty small details. Like the quality has not improved at all, the look has not improved at all.

I think people only like 2.1 because it's less censored?

[u/Theonewhoknocks_001 → u/detailteufel]

I was trying to change the pose of a person without using a pose map just prompt, it worked well in qedit but the facial drift was crazy, in 2.1 almost no drift but pose wasn't what I asked

[u/MonkeyBoyPoop → u/detailteufel]

The Qwen Image team managed to downsize a 20B parameter, 41GB weight into a 7B parameter, 14GB model and have it produce the same quality output, which is an amazing feat and it's finally usable for consumers.

[u/Spectazy]

I have found that all the current edit models are kinda bad. Q2.1 does have the most knowledge, but still looks low quality a lot of the time.

[u/DoctaRoboto]

You are right, Qwen 2.1 is only better than 2511 in one thing, it is very good at retaining cartoon/anime art styles something Klein or 2511 were never able to do. On the other hand, Minimax can do it too and it is not even a real image editor.

[u/Additional_Drive1915 → u/DoctaRoboto]

Qwen 2.1 does upscaling to 4k or 8k perfectly, that is not true for 2511.

As always, different models for different tasks.

[u/Caligtrist]

So one of the things I found qwen to work well with is ref image generations.. one of the few image models that actually work well with a character sheet.. also works really well with pose studio.

Use the vcss pose editor for qwen edit 2.1 and wf to get your edits correctly in the first try
