v1.0 - changes anatomy and overall picture quality
v1.5 - only changes anatomy
4B - only changes anatomy
This concept slider LoRA was trained to correct the anatomy / quality issues with Klein models.
The LoRA can't fix everything but it helps. It was basically trained so that negative weights have the effect of a negative stable-diffusion prompt, and positive have the opposite effects.
Weight 2.0 mostly keeps the seed intact and can be used to fix minor glitches, 3.0 fixes some more prominent artifacts.
The LoRA also improves a bit the overall quality of the picture, makes the picture more "clean".
Note on the 4B version:
I never managed to generate good quality images without the LoRA, so I didn't post images for it. I was able to confirm that the LoRA behaves similarily to the 9B version, but I probably won't update it unless the bad quality of the 4B model is due to my workflow.
Hope you like it!

could you do a klein-4b version please
Done, I'm not sure how to use Klein 4B for T2I though, each time I generate a person the quality is awful... So the 4B version is not tested, I hope it's good.
@l226 The 4b is used the exact same way as 9b but with the qwen3-4b text encoder instead of the qwen3-8b used with the klein-9b model ,
I'm using the fp8 version of the model and the quality Is decent enough but the anatomy is not with extra or missing fingers and limbs , that's why I thought is type of lora may help.
thanks for the lora, will test it and see if it improve things
At least it is not the level of SD3
@qek that's true , for me it's a huge step forwards since it's works good enough as an edit model that's not too big and is fast enough for lower end hardware , and since the model is apache-2 licensed I expect to see in the future full fine-tunes of the models that may fix it's shortcomings
@qek Ok ok so I do have an issue with my workflow then, the quality is way worse than SD3 for me...
I tried version 1.5 out on Klein 9b distill. It does seem to help address anatomy issues. I have the strength up quite high -> 3.0. And I'm using it with other loras but based on some initial testing I'm pleased. Thank you for sharing.
why so fancy with unintuitive iteration nomenclature? hurts my brain a bit
Doesn't take much then ;)
Here you go, I hope your brain stays safe for a while!
@l226 Huh, what now? Uh thanks for the fix and why should it take more to hurt a bit? Did i stumble into a hidden contest of sorts, some scientific question to be answered, "how much does it take to..."? Confusing it seems....🧐 Anyway, thanks for the "low effort" i guess? 🙃
@eyeonyou it takes little to hurt you
ziamge base plz
Thanks man! And 4b can produce just need to run it with loras. but this anatomy lora is working well!
Do people really need this? I almost never get morph monsters.
I don't even need negative prompts to begin with. You guys must do something wrong...
Some prompts are fine, others frequently anatomical horrorshow. Depends on how many positional instructions i put in. Maybe? Dunno.
I was skeptical in the beginning, but after testing for a while, I can confirm this lora actually works for editing images. And as another user mentioned, you can use a strength of 3.0 to remain on the safe side, or you can explore.
Really helpful and saves a lot of time, when you just can use the lora instead of doing inpainting/repair work. the overall image stays the same and the anatomy error gets fixed. Thanks a lot!
Is it possible to have a version without altering the original face ? I think it is getting changed everytime in v1.5
It's hard to have a LoRA that "fixes body parts" without having side effects on other body parts unfortunately. I think these are minor changes, and I don't want to spend a ton of hours perfecting it, sorry!
@l226 remove any faces in your dataset I think
works really well indeed
请问能否添加更多的训练数据集来增加lora质量，对我们很有帮助
Thank fk, I was going crazy with Klein models, is there an issue with their anatomy? All my dudes have penises coming out from their behinds.
This makes an incredible difference. Thank you.
do your sliders work on 9b base by chance?

Does Laura have issues with face changing? Many Laura systems alter faces, which causes the entire workflow to fail. If there is this issue, please point it out in the description.
