Flux 2 was not what we wanted or needed, but Klein appears to be what we deserved! Let's unlock the full NSFW potential of this model!
Kleinova focuses on professional photography and beautiful shots. It's vibrant and colorful and over the top.
Generation Settings
Most settings work, but I use:
12 steps
Euler
CFG 1.1
Editing
It works fantastically! Try it out as an edit model!
FP8 Download
For some reason, when you upload multiple formats (BF16 + FP8) on one model, which they now support, they hide the FP8 under the BF16 model group in the side menu...

GGUFs
Do it yourself:
https://github.com/qskousen/ggufy
Forge Neo
Should work fine using qwen3_8b qwen_3_8b_fp8mixed.safetensors and for VAE FLUX.2-small-decoder. Make sure to be on the correct preset.
Description
This version ended up being a bust. It CAN output good things, but it's mostly filled with genitalia and nipples through clothes and completely broken clothes.
Will revert and go back to previous versions, but uploading anyway for completeness :)
Expect better from the next version!

Why is v4 called in model version "bad" ?
Because I think it's a bad version of the model. The version description (right side) explains more. It looked promising during development, but when I was creating samples for the model showcase, I found that it was mostly poor results. So it's not a version I recommend. But maybe someone wants it so I uploaded it anyway.
It CAN do good things, but has a very bad success rate.
v3 took a step back, prompt adherence wasn't as tight as v2.2, now, with v4, honestly, it's awful. Nothing has been gained here. Not quality, not adherence, nothing. It's just straight body horror. Slow down. Reevaluate.
Yeah, I agree.
6tz I love your models I think you'd be the single top creator if you somehow figured out how to keep it more stable like Snofs and especially Jibmix. I appreciate the p*rn but I can see from extensive testing that even 2.2 is distorting a lot of the images as soon as you try anything complex or not closeup. It's hard to tell just randomly creating images, but if I'm looking at 25 different prompts with various models the difference becomes obvious how some of them can hold on and keep composition even when it gets tough and then others fall apart. So you get a model where it crashed and mangled like 5 times out of 25 and then another that crashed and mangled like 20 times out of 25 when the task wasn't easy. Anyway thanks bro, again your work is awesome.
Thanks for the feedback! I always appreciate good feedback.
It's hard to improve things like this. I mean it's very hard work. It takes a lot more time than throwing stuff into the trainers and just to see what comes out. Vibe-training and merging rather than precision measurements.
I wish there was more time available, but stupid base model creators keep coming out with new foundational models all the time. Give us some breaks and stop developing new models so we get time to use what we already have!
@6tZ Haha yeah it's really hard to keep up even as just a user, Klein 9B is the best right now, if you ask me. I went through them all spending literally months trying to systematically test each (many checkpoints, dozens at the same time automated, I'm pretty sure I didn't miss any of the top checkpoints including yours) and just recently switched from ZIT to Klein 9B. I avoid Loras entirely except one very well known and tested one for ZIT for the female part. ZIT is really awesome compared to SDXL even though SDXL does a few things better, but I found with ZIT, you really have to engineer each one to find the thing it does right. I was creating a standardized test for models and spent like a day just finding 2-3 prompts to use for ZIT that could actually legitimately compare checkpoint quality. Klein 9B initially looks the same, then suddenly it's so much better it's like holy f....
@ferrrett33 Yeah it's infuriating. But, on the other hand, we have such a wealth of options and variations, we should probably stop hoarding and FOMOing and just enjoy what we have.
Currently my favorites (of mine) is PerfecZion 3, Anima Perfection 2, and the KREAtivity model.
They slap buttcheeks!
in image edit it keeps changing the face and body type how to fix that ?
Prompt or mask
@6tZ what changes do i need to make it inpaint ?
@achref15008375420 No changes, just use it :)
sorry for wasting your time bro, but it does nothing it kinda completely ignores the mask :(
can u please give me an inpaint workflow or smth that disallows any changes in the face
@achref15008375420 I don't have it. You need to work it out :)
@achref15008375420 You can use PulID :) it's working with it but only with strength 2.0 of PullID.
Working well in the Inpaint in Forge
