    This is a very rough first attempt at an anatomy model that can create semi-decent artful nude women and men. When it hits, it can be really good, even with dudes. When it misses, it can be pretty ugly. I'll be working on better versions, need to dial in training settings and get a feel for how to train flux for quality output. I'm finding that you get best results using this lora in the 0.65 to 1.2 model strength range (leaving clip strength at 1.0). keep your guidance at 3.0 and CFG at 1.0, any more than that and it will fry and get bad looking really fast. I use DEIS and ddim_uniform at 25 steps

    trigger words:

    naked, naked woman, naked man with his penis out

    I'll be working on a few different versions of this, as the first one is a combo version, I'll release a female only/male only version in a bit, as there is some crossover from time to time, annoyingly.

    Description

    I am releasing 3 different checkpoints for this LoRA.

    3000 is more flexible and arty, lets you get more interesting styles.

    4000 is more strict about enforcing nudity and poses

    5000 is right on the edge of being overtrained. It has some pretty warm output and a lot of contrast, even when you drop guidance down super low. That said, it can really create some amazing stuff, especially if you "overdrive it" at 1.20 weight (tho it cooks the output too like this)

    toy around with weights and checkpoints, you're gonna get some magic and some freakshows. I'm sorry that not all of the nipples will look perfect yet, or that it will sometimes confuse bits and bobs. This model has very little nipple references and almost no genitalia references, so it's going to be some time and effort to bring this stuff back.

    This version now has a specific keyword that you can use to boost output, scg-anatomy-female. The lora also has a much wider variety of dataset images that provide a bit more variety in output. It's really good at nipples now, and you can bias breast sizes {small, large, huge, round, voluminous, saggy, tiny, silicon implants} breasts, boobs, tits. It also has a marginal understanding of the concepts of "vagina, anus, pussy, asshole, pubic hair" and even can give you {small, large, dark, light, pale, black, pink, puffy, erect} areolas and nipples. it can do ages young adult (I didn't test younger and you shouldn't either) to elderly, obese to rail thin, muscular to pregnant to on her knees, bent over, (lots more, have fun trying it). The list goes on.

    This version was trained on a little over 800 images, about 80% scraped vs 20% AI (AI was used to add racial and size variety, I was super super picky on what I used for inputs). All of the inputs were captioned first with Florence2, then hand processed to "remove the AI goofiness" and add explicit captioning to help add more natural keywording (just referring to a subject as "naked" and/or "nude" is usually enough, if you have a stubborn subject you can try describing more detailed features to bias the results).

    This lora is not anywhere near "explicit ready" yet, and I'm not training it with any pony style commands, no easter eggs there, sorry. It's an honest first try now that I'm starting to get a feel for how flux trains with a cleaner female gender focused train. I recommend running the lora in the 0.4 to 0.8 range. While there is the occasional body horror hiccup, 9 times out of ten if I check the same seed without the lora the problem is on base flux as well, so 🤷🏻

    Finally, I just want to mention that this took a lot of time and effort, especially the hand captioning work, as you really can't get ChatGPT to describe explicit material, and even the ablated VLMs suck at captioning naughty bits. I really appreciate it if you could give this a like and post some samples below. You get buzz, I get buzz, and hey, if you want to see more flux content (and I have A LOT more coming, not just nsfw stuff either) give me a follow, and if you're feeling really generous, click that coffee button and buy me a coffee, the tips I earn I put right back into my creations here. 💖💖💖

    Great, thank you for your work!

    Please, do remember, woman comes in all shapes and sizes, and that is specially true for breasts, so... add some diversity, if possible :)

    I'm trying! the base model really doesn't have much knowledge of breast sizes yet. I've had some luck with getting it to recognize nipple concepts somewhat, but I'm likely going to need to feed it a lot more references of all shapes and sizes before we can get it to loosen up a bit.

    scottyklei2Aug 18, 2024· 2 reactions

    I'm having trouble getting it to generate anything except what I would call huge massive honkers. 99% of the breasts I've seen in real life are maybe 40% of the size.

    And don't forget colors. Women come in all shades of skin, also. Great work, sir!

    NitrowingAug 19, 2024

    @socalguitarist slim women with small boobs exist. I'm trying to do some ballet dancers and they're all big boob/booty/hips

    DD_Ai_artAug 19, 2024

    @Nitrowing ok, this is acctualy not a specific problem of this or that model, all of them have very small variations in body/face/breast type. with very limited understanding that person can be large with small "anything", small with "large anything", and even poorer understanding variations.

    if one manage to get anything that is acctually simmilar to average real person, that is by pure chance, and i believe thst this is problem that exist from first model, they simply didn't have that amount of various pictures from real people.

    Fun fact, if you google "100 famous actors", and then paste that list in negative prompt.... you get very funny result, model simply don't know what to generate :)

    Thats the problem I have with flux. I mam unable to gett the diveristy of body shapes and sizes, colors and ethnicities that I am with SDXL and Pony..

    DD_Ai_artAug 29, 2024

    @HiProfileArt don't worry, it will be worse.... with all of hyperproduction of merging, joining and "improving" with ai images, diversity will be almost impossible, fate that all models share. in begining, images are bad, but you can be creative with character. later, images are great, but all model shares same gag character.

    About Florence2, is this better than GPT-Vision for captioning?

    Or why do you use Florence2 instead of GPT-Vision?

    I would always use GPT-Vision over Flo2, except in the case of explicit images where GPTV will demur and refuse to caption most of the time, and even if it does give you a response, it's things like "the woman is leaning over with her back to the camera". Flo2 doesn't give a shit if there is nudity, it just goes. It's about on par with LLavaNext 13B IMO, and in some ways better since it has good OCR, knows a fair amount of celebrities, gets context really well and can be fine tuned (check my discord server if you want more details on the best Flo2 fine tunes)

    crombobularAug 14, 2024

    @socalguitarist which version of flo2 are you running? I've tried it through pinokio and it refuses to acknowledge any nsfw situation by just never describing it

    SilmasAug 14, 2024

    @socalguitarist yeah, I thought so, that this could be a problem.

    But I got some really weird NSFW content when I used Vision, where GPT4 refused and marked the content as harmful. This was not via the API which I use when I have a bulk job.

    I've noticed that this model really loves putting rib markings on hips for some reason.

    This is bias from underwear/bottoms. This will improve with further tunes as we get down the line, right now it's a battle just to not have it put bottoms on everything.

    that's in the name of lora

    zoewilliams1998tgAug 20, 2024· 4 reactions

    Exactly! Especially struggles with women with penises. (I'm training a tgirl lora locally on a 4070super lol wish me luck I was bad at SDXL lora's)

    I cannot get this working with the recommended settings (25, deis, guidiance 3, cfg 1, trigger words naked, naked woman)

    nipples still looking ugly

    Maybe men need more penis photo references in the datasets Lora because it still hard to generate penis.

    I get unwanted unsolicited dick pics everyday, maybe I should start saving them and donate to the cause
