Due to filters im not able to upload proper Preview images for the models, will try to find a solution.

F2K 9b: Works best with strength 1-1.5. Works for T2I but also works great for I2I/Edit
F2K 4b: Not really recommend to use, as it has extreme body proportions issues, but 1 out of 5 images is decent. Lora training on civitai broke down at 9epochs. Will retrain soon.
ZiT: Trained on 350 images, mainly anime. Has some anatomy problems sometimes, but with strength 0.5-0.8 can put out some great images.

Flux1Dev and below:

Trained on 940 images containing:

Tentacles,Slime,Insects,Assimilation,Pregnancy,Lacatation,oviposition

works good from 0,3-1

tested on Pony as also everclear and other merges

SDXL version works fine on most base models.
