    For this V2 release I added those new concepts to the finetune.

    • Flash breast

    • Vaginal sex

    • Anal sex (a bit tricky still)

    • Facial Cum

    • Blowjob

    • Self Fisting

    • Vaginal Dildo

    • Cunnilingus


    This V1 is a general finetune Lora for Klein 9B for female and male nudity


    The v1 bring those concepts:

    • Pussy

    • Pussy spread

    • Anus

    • Hairy pussy

    • Penis

    • Ass Spread

    • Legs Spread

    • Upskirt

    • Gaping

    • Fix Klein jaggy areola

    • Ghost nipples

    • Puffy nipples

    • and more



    Use the Lora weight of 1 to 1.25

    This finetune help but doesn't fix Klein limbs issues.

    Some of your V2 samples are ON POINT. And with workflows... You're a good person doing good things... Don't listen to society!

    Good person doing good things, yeah sure... Making an NSFW version of an image editing model so enabling predators can make sexualized images of minors or random creeps to harass women or ...., what could fucking go wrong

    @aryanhooshi You can use a knife to make a good meal for your family or use it to do harm. But the problem is not the knife but the person using it.

    this is lokr or lora ?? Because it doesn't work in the Draw Things app.

    OG_OGFeb 23, 2026

    AWESOME, SNOFF AND THIS LORA ARE BEST IN CIV FOR KLEIN, THANKS FOR LORA. Also For DT. like me Those who can't run LoKr can convert it to LoRa using the converter via the link. I'm waiting for your GitHub follows and stars. https://github.com/kritikrap/LoKr-to-LoRa-Converter/tree/main

    hehetpFeb 28, 2026

    @OG_OG Sorry, could you find somewhere to upload the LoRA version? I've followed the instruction and tried many times, but it didn't work.

    OG_OGMar 1, 2026

    @hehetp I didn't understand what you meant. ??

    hehetpMar 1, 2026

    @OG_OG I mean could you upload the Draw Things usable version of this LoKr ?

    noobcannonAUMar 1, 2026

    @OG_OG it would be great if you could upload the converted Lora, please and thank you.

    OG_OGMar 3, 2026

    @noobcannonAU I can't do that, I'd be infringing on the content owner's rights. I'm sorry, but unfortunately you'll need to follow the instructions in the link and do it yourself.

    @OG_OG Hi, I did the file conversion and the 1 gb file went down to around 20 mb. Is this normal? I haven't tried this before and the size difference seemed pretty drastic.

    OG_OGMar 18, 2026

    @donnmat2502 use rank, Add "rank" to the end of the command; I recommend 256.

    donnmat2502Mar 18, 2026

    @OG_OG Thank you, for the original comment and this reply, these helped a lot.

    Not even, this part is built in the original model.

    @razzz just tried it without the lora, i see what you mean. kinda crazy that the model can do that on its own lmao. your lora definitely helps though.

    Soup_FusionFeb 16, 2026

    @razzz sry for bloating your model btw, i feel weird not crediting people when i use their loras but didn't realize i was like 90% of the images here lol. i trained a tentacle lora to build on what the model can already do but your lora still helps when it comes to general nsfw and penetration.

    I would take this for the nipples alone best nipple fix for Flux Klein, and thats just a side bar of this lora if everything else is as of high quality this is awesome. Although the ghost nipples are not quite ghosty enough for my preference, but they still look realistic so it's a preference thing rather than a criticism.

    Edit: my bad I had another lora that was effecting the nipples which does why overdone nipples which that it was able to fight that lora to get realistic nipples is amazing in and of it's self.

    Oh and addressing the limb issues of Flux2 Klein 9B distilled. If you are using ComfyUI using the node "Scheduled CFGGuider (Inspire)" and setting from_cfg: to 1.0, to_cfg: to 1.5 and schedule: to exp. has I have found almost completely fixed hands, feet, fading limbs and amputation issues.

    Asked gemini pro how that might be the case while it's probably hallucinating it said something along the lines that it add enough of a perturbation after the initial step to get it to reconsider the anatomy at steps 2, 3 and 4 rather than them being locked in at steps after step 2, but also doesn't introduce more errors as the exponential curve leaves step 1 almost untouched by the CFG and will ramp it up to about 1 - 1.05 in stop 2, ~1.2 in step 3 and 1.5 in step 4 so thereby injecting enough perturbation at each step to fix the the anatomy.

    but all in it works the worst I rarely get is an extra foot or something like that, at which point you might want to consider increasing to 8 steps and changing the end_cfg to 1.2.

    Thanks. I don't get it at all ))
