    I created it with intention of generation small breasts with Flux. It has some issues, but it can generate different sizes of breasts pretty well.

    How to use

    • On v1.0 and v2.0 positive strength means smaller breasts and negative bigger breasts (range is from -0.4 to 1.4)

    • On v3.0+ positive strength means bigger breasts and negative smaller breasts (v3.0 range is from -5 to 2.5 and v4.0 range is from -5 to 5)

    • No trigger words

    Known issues

    • Changes lightness/darkness of the image

    • Sometimes it generates blurry images

    Enjoy :)

    v2.0 changelogs:

    - improved nipples

    - improved close-ups

    - less likely to get exposed pussy or nipples when not prompted to

    - no longer changing faces dramaticly

    I will not train new versions for some time, but I still plan to improve this LoRA in the future. When there will be a proper way to train slider LoRAs on Flux or if I or somebody finds some major flaws with current version and I would be able to improve it.

    Thank you. It's working great for me in the few tests I've just tried....as long as you don't weight it too high.

    Yeah I know, but until there will be a way to train sliders for flux (I don't know of any). I can't do much about it, but its still cool that it works pretty well with somewhat decent range of weights.

    @This_Rock No problem, as I say it works great and better than all the others I've tried. :-)

    Hello, can you give me some tips, or a flow model of yours to work with, I'm a beginner

    It works pretty well but it changes the age at the same time. Mature women turn younger

    Thanks for feedback.

    I have two ideas why the deaging happens. The first one is flux's own biases, and asociating smaller breasts with younger women and the second one is from my dataset (I removed all photos with faces from v2.0 dataset so it is not from younger faces in dataset), but its still mostly feutures smooth younger skin. I will try to train a new model, but as I have said in changelog it will take some time as I am currently working on some other LoRAs.

    @This_Rock Thanks. I understand the challenge! FYI, for anyone else interested - this is the best Lora I have found for addressing the overly developed bias of the base model. And it works very well if you use it for inpainting characters whose look you are happy with in every other regard - just an extra step.
