Update 3/2/23: There is now also a <a target="_blank" rel="ugc" href="https://civarchive.com/models/15040/airoticarts-penis-model-lora">LoRA version</a> of this model available, extracted from v1.0.Update 4/2/23: For more examples, we used the <a rel="ugc" href="https://civarchive.com/models/15040/airoticarts-penis-model-lora">LoRA</a> of this model to help create the penises in our art, <a rel="ugc" href="https://www.reddit.com/user/AIroticArt/comments/129x9ff/the_beauty_of_couples_collection_14_aiassisted/?utm_source=share&amp;utm_medium=web2x&amp;context=3">The Beauty of Couples, Collection #14</a>.The present state of standard AI models is that they do not produce male genitalia well, if at all. Generating nude males usually results in eunuchs, or even completely emasculated figures. The penis and/or testicles are missing or completely disfigured in sometimes gruesome ways. Ironically, by trying to avoid training models on accurate human anatomy, they have produced models that actively disfigure humans in disturbing ways. <a target="_blank" rel="ugc" href="https://en.wikipedia.org/wiki/David_(Michelangelo)">Michelangelo</a> is rolling in his grave.We wanted to change that, so we trained a model with Dreambooth that specializes in detailed closeups of anatomically correct male genitalia, i.e. penises, testicles/scrotums, pubic hair or shaved, both flaccid and erect. And we're giving it back to the community.Example PromptsYou can simply use "a nude naked man" or "a nude man's penis" in your prompt and get some good results.You may add more details as noted in the version notes, including flaccid or erect, arm positions, the environment, indoors or outdoors, size of shot (full shot, medium full shot, closeup), etc. You may also add the unique instance keyword penflac or penerec to more directly specify a flaccid or erect penis, respectively.NOTE: If you download the inpainting model, make sure the filename ends with "-inpainting.ckpt" otherwise you'll get errors when loading in AUTOMATIC1111. Also, this model seems to do best at lower CFG values, around 4. Additionally, it doesn't seem to work well with the inpainting conditioning mask strength slider at lower values for some reason (in settings), so we recommend just keep that at 1.Here are more examples of prompts and settings:a closeup photo of nude naked man's flaccid penis, penflac, very detailed, 4k, Canon 5D, ZEISS lens, high quality Negative prompt: vintage, polaroid, black and white photo, b&amp;w photo, monochrome, illustration, boring, ugly, disfigured, mutated, blurry, 3D render, drawing, painting, cartoon, anime, rendered Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 1924014665, Size: 512x512 a closeup photo of nude naked man's erect penis, penerec, very detailed, 4k, Canon 5D, ZEISS lens, high quality Negative prompt: vintage, polaroid, black and white photo, b&amp;w photo, monochrome, illustration, boring, ugly, disfigured, mutated, blurry, 3D render, drawing, painting, cartoon, anime, rendered Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 4155553752, Size: 512x512 a medium full shot photo of nude naked man with an erect penis, indoors, in his bedroom, penerec, pubic hair, 4k, Canon 5D, ZEISS lens, high quality, photorealistic natural lighting Negative prompt: vintage, polaroid, black and white photo, b&amp;w photo, monochrome, illustration, boring, ugly, disfigured, mutated, blurry, 3D render, drawing, painting, cartoon, anime, rendered Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 801997243, Size: 512x512 a medium full shot photo of nude naked man with a flaccid penis, indoors, in his bedroom, penflac, pubic hair, 4k, Canon 5D, ZEISS lens, high quality, photorealistic natural lighting Negative prompt: vintage, polaroid, black and white photo, b&amp;w photo, monochrome, illustration, boring, ugly, disfigured, mutated, blurry, 3D render, drawing, painting, cartoon, anime, rendered Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 1374624039, Size: 512x512SupportIf you'd like to show your appreciation for this and help support our work, you can send tips or donations via Bitcoin to our Lightning Address here, grufftoad29@walletofsatoshi.com (not an email address).

AIroticArt's Penis Model

This is the first version of this model.hash: e5a80698md5: c94066c5dd9335f8691e09ed87113cb9There were two basic kinds of images and captions used in training, as two separate concepts:<ul><li>30 flaccid images, with detailed captions like "a medium full shot of a nude naked man with a hairy body standing in a room with a lamp and a picture frame on the wall, flaccid penis, frontal, folding arms, pubic hair, circumcised, glans penis, scrotum with testicles, head and face out of frame, penflac"</li><li>30 erect images, with detailed captions like "a closeup of a nude naked man's erect penis, bare legs, no shirt, outdoors, shaft, cock, dick, from the front, scrotum, testicles, shaved, no hair, smooth skin, glans penis, frenulum, penerec"</li></ul>Training Parameters<ul><li>Dreambooth training (Shivam)</li><li>60 images (30 flaccid, 30 erect), manually edited for clarity</li><li>512x512 resolution</li><li>BLIP initialized captions, then manually edited to add detail</li><li>DDIM scheduler</li><li>SD 1.5 pruned-emaonly base model</li><li>fp16 precision</li><li>600 class/regularization images, 512x512 (generated with "a photo of a nude naked man")</li><li>19,100 steps (training text encoder only at start, ~1%)</li><li>LR 2e-06</li></ul>LimitationsFor this model we trained circumcised penises, and in the future we want to include uncircumcised penises with foreskin intact as well (erect penises look similar already). The model can still generate mangled or duplicated genitalia that can be disturbing. Sometimes indoor shots produce too much film grain from low-quality training images. Sometimes prompting for flaccid will generate erect, and vice versa. A greater variety of training images, with a variety of different anatomy, settings, poses, and crops, would produce more variety in inferencing. This model was trained mostly on closeups, so might be best used for inpainting fixes (an inpainting version of this model is also available!). Training could be done on more ethnicities. Full precision could be used, as well as the full ema+non-ema base model. These are areas for improvement in future versions of the model.
