- V4.1 "Back To Basics"

by ModelsLab

I went back to the drawing board because I was not satisfied with the last 4.0 version. I carefully examined what worked well in the previous versions and what could be further improved. After weeks of testing and adjustments, this is the result.

So, not a checkpoint filled with Loras (which we see a lot lately) but a flexible version that works well again with Loras and Textual Inversions. And whether you like long prompts or prefer short ones, it should work well.
