I've seen some people ask for this, so here's my extremely medium-effort take on it

==================Illustrious=================

This model is ????? AF (obviously), neg (nipples, ?????, motion lines) if you're trying to not show them.

Works best with solmeleon, cfg 5 or so

r0b3rts, thick lines

masterpiece, best quality if necessary

Illustrious is weird so you might have to shake out some negs like

3d, realistic, render

==================Pony====================

TLDR: r0b3rts, source_cartoon

NEG: (holding, (text), (borders) (tan lines) (tears) - depending on what you want

Enhancers (Line art, flat colors), comic style

Roberts is known for ???? artwork, consisting of sunglasses, tan lines, bikinis, crying, at least 3 vans, and copious amounts of NC. I specifically trained it without masking any speech bubbles because A) I'm lazy and B) I think that that's part of his charm, along with his disney-esque artstyle. Pony largely ignores captions and text, but speech bubbles and red text will bring them out stronger, or you can neg it to remove it. Pony is pretty good about not showing captions most of the time.

For you on-site generators, https://civitai.com/models/534425/hoseki-lustrousmix-pony-xl does a pretty good job with it, as does malaAnimemix (which isn't on-site)

For generations closer to his actual quality of hand-drawn, remove any higher quality tags from your generations, do not high res fix and maybe only do score_7_up. Some examples are with only score_7_up
