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.Community and SupportJoin The Bulge Discord at <a target="_blank" rel="ugc" href="https://thebulge.xyz">https://thebulge.xyz</a> if you’re into gay AI art—it’s a great place to share and learn. If you want to support the project, whether with feedback or donations, it’s much appreciated. Current StatusThe model isn’t perfect, so don’t expect flawless results.PurposeAndroFlux 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 DetailsAndroFlux 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<ul><li>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.</li><li>Captioning: Captioning was crucial in training. Contributions came from the AndroAtlas dataset, part of the AndroFlow project. <a target="_new" rel="ugc" href="https://civarchive.com/user/ephermeron01">Ephemeron01</a> from The Bulge Discord assisted with captions using models like llava-hf/llava-v1.6-mistral-7b-hf and a custom-trained PaliGemma VLM.

Use with the Perturbed Attention Guidance node for best results. I use a value of 2.6V26 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.
