Example images are strength -8 through 2, with the last ones being mostly between 0 and 1. The first image is strength 0.7.

I trained on WAI illustrious with ai-toolkit on about 800 images I liked. What came out was very interesting, especially when used on the wai model. Experiment with strength between -8 and +2

It drastically shifts from a nice anime style in the negatives to boosting the "WAI look" between 0 and 2.
