Version 1.1 is the latest version of the earlier, more anime-focused Version 1. It is made of the same models, but the mixing method is slightly altered, as are the model weights. If you like the style of Version 2 over Version 1, this isn't going to be your cup of tea, but don't worry; there'll be a new version improving on Version 2 soon (part of the method refinement that happened here was necessary before I could move on).
Version 1.1 does some things better, and a few things are not quite as well as the earlier version. Prompting (in my opinion) is improved, but it takes an extra generation or two for me to get images with exactly what I want. Lower CFG values seem to produce better images, so sometimes, it's better to start lower with a simple prompt to see what the model comes up with. It does very well with NSFW imagery with very short and simple prompts.
