I’ve studied the samplers a bit and done some of my own experiments with them, and I’ve arrived at some tentative conclusions for what to do with them.

The Classifier-Free Guidance Scale, or “CFG Scale”, is a number (typically somewhere between 7.0 to 13.0) that’s described as controlling how much influence your input prompt has over the resulting generation.

In this series of posts I’ll be explaining the most common settings in stable diffusion generation tools, using DreamStudio and Automatic1111 as the examples.
