AndroFlux is a LoRA model made for FLUX.1 dev by Black Forest Labs, because there’s a glaring lack of accurate male anatomy in AI models. I’m trying to fix that by making sure AI can depict male features more accurately, balancing out the overwhelming female-centric content you see everywhere.

Current Status
The model isn’t perfect, so don’t expect flawless results.
Purpose
AndroFlux is all about making sure AI models can represent male anatomy—especially penises—accurately. With that said, it also has a general photographic aesthetic and focuses on twinks so it is still useful for other SFW purposes. It’s a step towards more balanced AI-generated art.
Technical Details
AndroFlux was built and tested primarily on FLUX.1 dev, but it should also be compatible with the Schnell base models, including the quantized fp8 version. These are distilled models, making training tricky and affecting the LoRA’s performance, requiring a lot of optimization.
Training Process
Resolution Journey: I started training at 1024px, but the model wasn’t converging, so I dropped to 512px. The quality wasn’t great, so I ended up at 768px. This resolution offers a good balance between detail and training time.
Captioning: Captioning was crucial in training. Contributions came from the AndroAtlas dataset, part of the AndroFlow project. Ephemeron01 from The Bulge Discord assisted with captions using models like llava-hf/llava-v1.6-mistral-7b-hf and a custom-trained PaliGemma VLM. Specific prompts like "man, penis" and the activator "AndroFlux" were also used in later versions.
Acknowledgments: Huge thanks to bghira and Terminus Research Group for their support, including providing an A100 for some of the training runs.
Usage Tips
For best results, use prompts that specifically mention male frontal nudity, such as "penis."
Recommended settings:
Resolution: 1024x1024 or 832x1216
Flux Guidance: 3.5
LoRA Weight: Start at 1.0, reduce to 0.5 if artifacts appear
CFG: 2.0 (1.0 will be faster though)
Suggested Prompts
A nude man in his {late teens | early twenties | early thirties}
His penis is {erect | flaccid}
His penis is {large | small | average}-sized
Version History
See "About this version" on the right for version-specific updates.
Description
This version is just about as good as mixing v15 and v17, so I thought I would release it. Beware, there's still a lot of weird anatomy though (especially hands).
You will see nightmare fuel and overly long dicks. You have been warned.

This lora just keeps getting better and better. I hope you keep improving Bananadiffusion to. Did you update the lora on Tensor also?
Someone beat me to uploading it on Tensor :/ Really frustrating but I contacted support. It should be on my profile soon.
Your efforts are admirable. However, it's not working well for me. I tried entering everything exactly as it is in the workflow you created, 'Flux With CFG Workflow [AndroFlux],' but it never exposed the penis. Am I doing something wrong?..
Look in your comfyUI console for any messages like "lora key not loaded" which is a common issue with comfy. If you see these messages, you'll need to update/restart Comfy and try again. Also make sure you're not using the NF4 version of Flux (I use the fp8 all-in-one checkpoint). Let me know if it works :)
@markury It seems like the ComfyUI update was the issue. Thank you for the quick response!
Do you have a link to the dataset/do you know if it includes transfem subjects as well or just men?
It's mentioned in the Discord, I think, that the LoRA will basically add penises to whatever
have you tagged body and pubic hair? Would be great if these could be controlled
Is there an updated link to the discord? It doesn't seem to work.
Great LoRA! Love it, especially when used with OnOff for Flux dialed down to .70.
Has anyone figured out prompts to create slightly more detailed/realistic bodies? Right now when paired with OnOff for Flux if I dial up this LoRA to 1.0 it does a fantastic job on the penis but washes out the body, and if I dial it down to .85 or below it tends to improve the body details somewhat but loses definition of the penises. Not a big deal, still works as a fantastic LoRA, just figured someone might have a good idea of how to improve the outputs. Or maybe the problem is my CFG? (I try to keep it at 3.5–4, which is low enough that the pictures often don't follow the prompt, but if I go up to 4.5 it starts making the body more washed out.) Thanks for any thoughts!
Edit: I think I may have figured it out at least part of the way – starting the prompt off with "High resolution" seems to be magic(ish) words.
Thank you for your LoRA! Here version 1.9 works very well with a weight of 0.8 we are still far from perfect but even the girls (aka vaginas) are not very good atm. I was not expecting a penis LoRA so good and so fast! Keep upgrading please! I am running your pod to train my private LoRAs!
Works very well already. I've been trying it out with male-female scenes, but I've noticed it doesn't respond well to prompts trying to make the man black.
Prompts like "African-American man with black skin" or "Nigerian man..." tend to result in what looks more like middle-eastern or north African (e.g. Tunisian, Egyptian).
Is the training data very much biased towards white caucasian men?
If your still having a few problems with Androflux maybe you should contact the creator of this Tensor model. Maybe he can give you some pointers. https://tensor.art/models/762743199417728629
Can someone post good examples of prompts? TIA.
