It is not trained to make big breasts at all. Mainly it works quite nicely with realistic models like celebrity embeddings etc. depending which stuff they've done with.

(Actually this is quite old model but today as I finally fixed my Hugging Face page I noticed it had a way over 500 downloads (during last month) from there. So I thought maybe I should finally upload this to Civitai also.)

This is basically my own Base model that I use for creating my other merges.

I prefer using After Detailer (Adetailer) https://github.com/Bing-su/adetailer for fixing faces.

I compared Full and Pruned version, to see the real differencies. Here you can see the results.
