Z-Image is a lot more robust, especially with LoRAs in picking up core changes without overfitting everything else, so I think there will be better results with Z-Image if you aren't looking for overly explicit, uncensored NSFW results.
Provides huge fake breasts with a good mix of nude, sexual attire and fully clothed data so those clothes are realistically stretched to their limits
While this is trained on realistic images, I have had some pretty good results on anime characters as long as you add 'realistic' into the negative prompt.
The primary tags are:
gigantic breasts
huge implants
Note - using these and applying both with the same prompt strength gives breasts the size and shape of rounded breasts and fine-detail.
If the breasts are drooping too low, you can also add 'sagging breasts' to the negative prompt.
There is one additional tag that has alot of trained data applied
breast overhang
Using this prompt, while not always occuring will make the shirt/dress loosely drape downwards from the breasts rather than puckering up underneath them

This was super needed, thank your for developing it
Thanks. There are very few people in the world with implants like these, so one of the main issues of trying to make a LoRA like this using only 100% real images is lack of subject diversity. I used a workflow to swap faces and hair to try and make it a lot better and avoids depicting real people. Unfortunately in this one, realistic results often end up with hair pulled backwards still - it has been fixed in my new Z-Image lora, maybe I'll update this one for SDXL users
Do you have any recommendations for making this work with CyberRealistic Pony? That model makes amazing faces and backgrounds but maxes out at quite small (relatively) breasts.
My example images uses CyberRealistic Pony. I'm not super pro at making these models so not sure how to improve the weighting, but if you look I put in alot of brackets around gigantic breasts to emphasise this. Like 4-5 braces gives you the biggest, and I set the LoRA strength to 1.2-1.4. Again, I dont think it should be like that but if I find a better way to train these I'll make a v2.
