The Anti-Crispy Update

This version is a simple dial-back to cool V1.3 / V1.3.5's jets, to reduce the crunchiness, aggressive darkness, general rigidness, and make it less demanding for low CFG and high step count. This is done by a simple merge-back of SD 1.5 (which had an add-difference merge of 0.70 with the noise offset) into V1.3.5 at 15%, and then an extra 2% noise offset on top. This does affect some things -- depending on the kinds of prompts you write, you might not notice much, or you might notice a lot. Interiors aren't as imaginative and smooth, yet making genuine art is a cleaner experience with less crunchiness. With the model's behavior reined in a bit, some things might be a little worse, but nasty crispiness and constantly getting the same posing and framing should be less of a prevailing issue now.

Tips:

Keep CFG fairly low (e.g. around 6-7, but 10 is too high, things get extra crispy).

If your results don't look very clean or have an artifact, you'll probably need to re-run with more steps -- this model can be more demanding than others.
You do not need to prompt a bunch of detail/quality phrases, or use 'negative embeddings' or massive negative prompts.
To control detail level for less detail-dense art styles, try putting 'photo' and 'realistic' in your negative prompt.
If your images are coming out a little dark or contrasted for your liking, try putting 'low light' in your negative prompt, or 'dark' for brighter colors if it's not a lighting issue.
May occasionally need to put 'paint' in negative prompt when prompting for paintings and you're getting weird extra colors or actual paintings in the scenery.

Oddities:

Eyes and especially teeth are sometimes a bit off.
Trying for realism with natural landscapes doesn't normally look great.
