Flux Klein 9B v1.5 BETA
Beta release because there's some improvements but not a huge upgrade, and is kind of broken in some areas compared to v1.
Experimenting with different captions and training styles with mixed results. Penises generally look good and has more variations, but also prone to distorting.
Describing the type of penis in the prompt is highly recommended, like a "hung and uncut penis", though some combinations work better than others. Check the trigger words.
Uncut (facing down) penises are mostly improved. Erect and circumcised are still difficult to create consistently, and the 'dick pic' angle still doesn't work well.
Body proportions look better.
Edit mode does a better job at retaining the subject's appearance.
Next update will definitely need to fix the weird distortions or those instances where it doesn't know where to place the penis. Decided to release this because you can still good results, but it's not as consistent.
A general penis LoRA intended to create different types of penises on different types of skin tones, though it still needs some work. This page is currently only focused on the Flux.2 Klein and Z-Image models. As a disclaimer, please use this model responsibly, especially when using the edit feature.
This was trained on a mix of high resolution close-ups and full body photos of various penises. 76 images overall. Most were flipped on the x-axis but some weren't due to text being in the image.
Trigger words: penis, erect, flaccid, hung, foreskin, circumcised, uncut, glans, frenulum
I've spent the past couple of months staring at deformed blobs of flesh on men's crotches. If you support my hobby, feel free to buy me a coffee: https://ko-fi.com/avrik

This works great, much better than the other one posted today.
Thanks! Though I still need to iron out some of the prompting issues if its possible.
Great results!
Thanks!
Hi! This LoRA is insanely realistic (and I’m a big fan of your LoRAs too). Shame it’s not coming out great for me in Draw Things though. Even at full 100% weight, the penis still just renders like a blurry, skin-textured cylinder.
I noticed you’ve replied under other posts saying you use DT too — have you tested this one in Draw Things? What kind of config/weight/prompt setup works best for you there? Any tips would be awesome. Thank you!!
@Ezrame Very curious to know this as well! Have tried everything I can think of...
@Ezrame In the mean time I bought better computer and now I am using ComfyUI. Indeed in DT loras for Klein doesnt look good.
The quality is excellent. Please do a circumcised version!
The main example image lacks foreskin.
Circumcised will usually show up in erect penises and in the new z-image version it should show up while flaccid or hanging. It's kind of random though, because I think it confuses the words "circumcised" and "uncircumcised".
this topic in AI fascinates me. rorschach, o rorschach, what do i see.
amazing! you are the king!
this is what I always wanted, different skin tones, textures, cut/uncut, flaccid/erect all in one.
Does it do also hairy and hairless?
Sorry, late reply but yes I did make sure to caption the body hair amount. Try keywords like hairy, shaved groin, trimmed pubic hair, bushy, or just the color of the body hair.
nice, I'm gonna stick to Klein, seems z-image in general doesn't train well. I'm super excited for the next Klein version. There are already a few penis loras for Klein, I think it'd be great if everyone shared their datasets and created an ultimate penis lora
@ForeverNecessary737716 Something's weird with z-image base. I hoped it would be easier to train on compared to Klein but it hits a brick wall at some point in the training. On the positive side it helped me adjust my dataset a little better for the next Klein update.
Also I recall trying to contribute to a project to make a gay male-oriented model but I didn't have time to clean up my dataset before they started training. This was years ago though so I'm not sure what happened to that.
@Avrik I don't know, but if there ever is one, I hope it will fix issues with male representation in AI models:
• Blonde men with dark eyebrows, dark roots, dark shaving shadow, and dark body/pubic hair. (Not all blondes are artificial.) Some models, when prompted for platinum blonde, provide extremely artificial nearly white bleached hair. This drives me bonkers because I love real blondes and redheads. Genuine blonde and redhead appearances have traditionally been difficult to obtain via local AI at least.
• Too-low body fat and excessive prominence of abs. That doesn't mean obesity is the goal.
• Testicles are small but the penis is big. Some guys are like that but there is a lot more variety.
• No way to control the size of the glans relative to the rest of the penis. Too many models have been restricted to a small glans on a long penis.
• No way to control the curviness of the butt. Prime Thiem and Roddick, for example, are a lot curvier than what I have seen models be able to produce. Some models produce butts that look more like female butts shoehorned into a male body, like some recent Chroma shots I saw. Mediocre to poor control over the shape of the butt, at least for males, is an issue with a lot of models, I think. (How square, how long, etc.)
• I think it was Flux 1 that had a very restrictive number of male faces, usually long and gaunt with a long nose.
• Large eyes not being an option. Or, if they are, they don't look natural.
• Not being able to make a face or body a bit more feminine without the model going overboard and making someone who looks like they're XXY, especially the face and hips.
• Always forcing stubble or a very visible shaving shadow.
• Putting moles all over the skin as a way to make it 'realistic.'
• Not being able to make paler/pinker puffier larger nipples without things going toward XXY territory.
• Skin looked too haggard, dry, tanned, and wrinkled for someone of the prompted age. A 24-year-old doesn't always look like a 34-year-old who works outdoors in real life.
• Poor selection of hairstyles.
• Mediocre to poor XXY-style bodies. Instead, at least with Wan, most lora makers simply stick a penis onto an otherwise fully female body (especially the faces, which aren't at all masculine). It is good to have the full range from ultra-macho to ultra-feminine, with fine control throughout the range.
• No height control. I like short guys and tall guys equally.
Does this have a control for testicle size? Most penis loras seem to come with small testicles. Pubic hair control is also appreciated for a male genitals lora.
I did caption the testicle size but you won't get anything extreme and unfortunately a lot of them were pretty small lol or normal size. I'll see if I could find larger sizes in a later update.
@Avrik Thanks. For history buffs, at least in part of ancient Greece it was once the fashion to have large testicles and a small penis.
