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
Use with the Perturbed Attention Guidance node for best results. I use a value of 2.6
V26 is a complete re-train and an incremental update over v19. It should be a little bit more stable at the default strength of 1.0, but will still produce a lot of nightmare fuel. You might prefer v19 for more flexibility and diverse outputs.
It was trained for 4600 steps with multi-res and then finished off for 2000 more steps at 1024. This is also a merge since even after the 6600 total steps the effect was weak.
Despite cropping, it also tends to introduce false watermarks.

Your LoRa is not being recognized by Civitai crossposting, if you trained it with Ostris Aitookit you should consider looking at this: https://github.com/ostris/ai-toolkit/issues/130
Most of the penises generated by this lora are too small to understand upturned penises and erect penises, weak penises.
I am genuinely impressed by the attention to detail and the effort put into AndroFlux. It’s refreshing to see a LoRA model that finally addresses male anatomy representation in AI-generated art. The accuracy and focus on male-specific features are unparalleled compared to the usual female-centric models we see dominating the community. AndroFlux is not just a model—it’s a significant step toward balancing the artistic representation of men in AI. This model adds an essential layer of realism, making it invaluable for creators who want to achieve nuanced male anatomy in their work. Whether you're generating male torsos or full-body compositions, AndroFlux consistently delivers well-defined and authentic results.
Improvement Request:
However, one area that could benefit from further enhancement is the representation of male nipples. While AndroFlux does an excellent job with general male anatomy, nipples often lack the same level of detail and realism seen in the rest of the model. This stands out even more when compared to how thoroughly female anatomy is captured and represented in other LoRAs across the community. Male-specific anatomical features are frequently underrepresented, and improving nipple definition would add another layer of authenticity. As the open-source community continues to refine these models, it would be fantastic to see AndroFlux set a new standard by addressing this gap, ensuring that male anatomy receives the same attention to detail and artistic representation as its female counterpart.
Thank you for your hard work on this model. I’m looking forward to future updates that push for more complete and accurate male anatomical representation!
I agree, it'd be nice to either have nipples in this or a male nipple lora (there's a nipple fix lora, but trained on women, it sorta works at .4 weight)
Doin Gods work out here
<3 the work
"balancing out the overwhelming female-centric content you see everywhere."
THANK YOU!
LMAO - SAY IT LOUDER FOR THE PEOPLE IN THE BACK!!!
Seriously im sick of it.
