Zootlustrious [Aesthetic Illustrious XL Refinement]

V2.0 specific notes:

See "About This Version" for more details, but I'll note here V2 is NOT a continuation of or in any way to related to V1, rather I retrained everything from scratch against base Illustrious to make V2.

General Notes:

This is Illustrious XL 0.1 "Raw" with the following changes:

• further trained on an additional dataset of 2000+ hand-selected and well-captioned images for roughly 80 epochs or so, as of V1
• DPO Lora injected @ 0.25 strength
• SPO Lora injected @ 0.75 strength

This checkpoint aims to make the default output style of the model more consistently clean and coherent based on standard anime model quality tags (e.g. masterpiece, best quality, high quality, absurdres and so on), without actively degrading or "erasing" any of the base knowledge of Illustrious.

Lower CFG tends to give better results, I recommend anywhere from 4.0 to 5.0ish with Euler Ancestral Normal or sometimes Euler Ancestral Karras.

Maintaining "high similarity of composition" on a direct seed-to-seed basis for the same exact prompt versus base Illustrious was not a concern, however, as the base model is not in any way one that generally produces consistent outputs to begin with, nor are the outputs of the base model necessarily actually good at all and worth aspiring to maintain to begin with (at least in my opinion).

If you're choosing to use named artist tags such as e.g. hungry clicker or cutesexyrobutts in your positive prompt, using negative quality tags along with them in the negative prompt (such as e.g. worst quality, low quality, normal quality, lowres) is generally still beneficial and tends to improve the accuracy of any given named style, however you don't necessarily always need (or want) to still use positive quality tags at the same time as named artist ones.

Do not use the DPO or SPO loras again on top of this checkpoint, they are both already injected at carefully chosen strengths, running them again on top will almost certainly make your outputs worse.

For "hi-res-fix" upscaling with this checkpoint, I personally recommend using either 4x Foolhardy Remacri or 4x FaceUp DAT as the upscale model.
