irAsu v1.0

sample1
sample2

irAsu is a second-stage finetune of Illustrious XL 0.1, which fixes the coloring, anatomy, and background of the images generated by the model.

Standard Prompting Guidelines

The model is finetuned from Illustrious XL v0.1, which is trained with danbooru tags. However, there is a little bit changes on dataset captioning, therefore there is some different default prompt used:

Default prompt:

1girl/1boy, character name, from what series, everything else in any order, best quality, amazing quality, very aesthetic.

Note: The quality tag masterpiece has been replaced with best quality due to reports that it often caused unwanted side effects.

Default negative prompt:

lowres, (bad), text, error, fewer, extra, missing, worst quality, jpeg artifacts, low quality, watermark, unfinished, displeasing, oldest, early, chromatic aberration, signature, extra digits, artistic error, username, scan, [abstract],

Default configuration:

Default configuration: Euler a with around 25-30 steps, CFG 3.5-5, and ENSD set to 31337. Sweet spot is around 28 steps and CFG 4.
