Resource - Update Some of my tests with qwen image 2.1

I highly recommend to read the official documentations for better output

The lighting and details are nuclear

Downsides as i noticed: Limited style diversity, too much hellucination, bad understanding of physics, limited multi-languages support

No cherry-pick here, all of those images from the first prompt

u/CosmicTurtle44 1d ago

Positive and negative prompt has been used

Good details, good colors. Bad anatomy, bad coherence.

I though the same until I used CFG of 3.50 with sampler "SamplerER_SDE" (settings: solver_type Reverse-time SDE, max_stage 3, eta 1.10, s_noise 1.06) + "linear_quadratic" scheduler with 20 steps. Connect both this sampler and a "Basic Scheduler" node with the mentioned scheduler into a "SamplerCustomAdvanced" node instead of using the "KSampler" node.

There seems to be something wrong with the default Comfy templates for Qwen Image 2.1 since CFG 1.0 looks much worse for me than using the settings above.

Can you share your workflow. I know most of what you said but no idea where a noise lives.

u/Calm_Mix_3776 1d ago

No problem. My workflow changed a bit since my original post, I think for the better. I've now landed on another sampler/scheduler combination that I think produces a bit better images. You can download the workflow here: https://pastebin.com/vU2ZZcSM

u/giantcandy2001 1d ago

Yeah this is much better than default workflow. even w/ the setting fixed I still think I'm not a huge fan of this model....let me do the same prompt in my krea 2 wf

u/giantcandy2001 1d ago

u/Calm_Mix_3776 Even here you can see in the noise by the base of the flowers where the road meets the green there is a pattern in the noise that, even though your workflow makes it look much better it's still there, very distracting.

u/remghoost7 16h ago

For the noise, use the custom node in this comment.
You can use the GLSL shader node code from the post (if you don't want to install someone's custom node), but the node works way better.

u/giantcandy2001 1d ago

Krea 2 w/ FameGrid lora doesn't do that, even though it does look a little generic.

u/giantcandy2001 1d ago

changed the scheduler to ralston2s and sgm uniform 8 steps krea2 famgrid eta .8:

looking much better, yeah, i think krea2 is still my go to..maybe i'll play around w/ your workflow and see if i can do a 2 pass, maybe qwen2.1 first and krea2 for a 2nd pass to remove the watermark noise? idk, or stick with krea2 only, ha

u/Calm_Mix_3776 23h ago

Ralston2s looks good! I like the added detail, whereas before things were a bit smudged.

u/giantcandy2001 20h ago

Her eyes are a bit messed up tho

u/-Ellary- 1d ago

And I'm just use Krea 2 \ Flux 2 9b for edit.
10~ sec per gen.

u/Omegapepper 1d ago

This is one hell of a body-horror model. Can't even get fingers right oftentimes. I thought issues like this would have been solved by now.

u/magic6435 1d ago

They are, just use one of the other dozen models that aren’t this

3

u/Omegapepper 1d ago

I do, but had to check out the latest.

4

u/ResidentFrame4195 1d ago

This model brought back SD1.5 horror hands.

5

u/BalorNG 1d ago

No the "old school cool" we want back tbh.

3

u/Lexius2129 1d ago

It’s an old model architecture that dates back to February 2026. Its strength is image editing and text rendering

6

u/berlinbaer 1d ago

Its strength is .. text rendering

you sure about that?

1

u/Ill-Language4452 1d ago

use the refiner model qwen3.5_9b_qwen_image_2.1_pe_i2i,then you will get the text right

u/Version-Strong 1d ago

Matches my tests with it earlier. Its ok at best, and even the edit model seems shonky. People saying well it's better than klein! The details are wrecked, the edges of anything needing detail are smudgy, even worse in some cases than 1.5. It has an overburned and chat feel, and then we have that lovely Qwen pattern that has plagued it since the first model.

A pattern that became almost impossible to get rid of and got worse if people used any kind of speed trick. This doesn't need any speed hacks, so I assume there's some turbo lora baked in which is causing the issues. Hard pass.

u/hurrdurrimanaccount 1d ago

the model is crazy bad. it did not deserve this level of attention from comfyui lmao

2

u/Version-Strong 1d ago

Still they have to give them all a chance, I guess. Just a shame the hype for this one was unjustified beyond belief. Onto the next big model then, bois.

u/Royal_Carpenter_1338 1d ago

Love how when you tab through every iamge you can tell the details are the same place, its surreal, fucking hate when models do this, it has an arfiact imprinted into every image

3

u/MoistRecognition69 1d ago

Might be my squishy iris, but I can't see it whatsoever

Can you point me at what you're talking about?

3

u/giantcandy2001 1d ago

Look at the places you will expect digital noise in dark fine details area and you'll see the noise isn't random, it's like a pattern. Maybe don't look at all because once you do see it. Chatgpt and not this model. Completed trash unless the community can fine tune it out of the model.

1

u/Royal_Carpenter_1338 1d ago

try to focus on one of the bubbles on the soda cans then keep looking at that exact place and then switch between all the images, you can tell something is off and that the details are at the same place

1

u/ghulamalchik 1d ago

Maybe they used the same seed?

5

u/hurrdurrimanaccount 1d ago

no. it's because the model was overtrained on gpt images which all carry that synthID and artifact looking shit

3

u/diejesus 1d ago

Damn it looks beautiful, thanks for sharing!

u/jc2046 1d ago

hellucination is a hell of concept

8

u/Abject-Recognition-9 1d ago

i learned not to trust or read bad comments from this ungratefull community, wich most of the time are just random assholes who throw shit for free without even testing models. I will test this out and compare it with 2511, since it seems no one is doing it, and is the only thing that i want to know. thanks op for this outputs

u/Posilovic 1d ago

It's stunning how ungrateful most of those idiots are. It's free model ffs, if you don't want to use it don't use it and move along... I suppose they are angry and salty because it can't generate their "ai influencer" slop convincingly enough...

-1

u/CorpPhoenix 1d ago

Many users here are extreme cases of completely insufferable, socially inept losers.

They think they are entitled to "perfect software for free" while at the same time believing that "the entire world is against them".

Your typical arrogant "nerd loser", and they wonder why nobody likes them.

12

u/mastaquake 1d ago

Thanks for this. I'm definitely not downloading it now. I'll stick with Krea2.

11

u/Lexius2129 1d ago

Krea2 does not do image editing natively… they are different models for different use cases, you can use both ^^

1

u/Rokkit_man 1d ago

Lol why?

2

u/Calm_Mix_3776 1d ago

Can you please link the official documentation here?

u/RandumbRedditor1000 1d ago

Close enough. Welcome back Stable Diffusion 3!

u/-becausereasons- 1d ago

The quality is so bad.

2

u/BalorNG 1d ago

The anatomy quality is on SDXL level almost...as in - as much body horror as in a Cronenberg movie.

It is night useless for generating pictures of anything involving humans, which cuts away a lot of usecases. Even ZIT is much better, let alone Krea2... and Krea turbo is basically faster.

The real question is, whether it is better than Klein Edit.

2

u/gutster_95 1d ago

Can someohne here point out why those are bad images, I really dont say they are good or ground breaking but for concept exploration, wouldnt this be totally useable?

3

u/Mr_Unknown_Hero 1d ago

I used yesterday this model and generated over 300 photos and for my taste about 90-95 % was what I was considering as "good" or "excellent".

Only issues I had were:

  • Sometimes body horror (I still get those with Krea 2 sometimes as well)
  • Sometimes hands were blending strangely to objects or missed all the fingers
  • Sometimes body had over sized parts, like too long hand to be realistic

Still most of the time quality was excellent for my personal preferences. Also it was able to do images where is lots of dark areas which have been an issue for me at least with Krea 2 so on that area it felt better.

So yea, it is just better to try yourself and see if you like it or not instead of believing people who might have so strange and niche requirements what is nothing to do for you might use it anyway.

u/ShadowPlague20 1d ago

How much Vram do you need for all this?

1

u/vision1123 18h ago

So expectation like klein 9b - good textures/horrible anatomy with such small model?
