How to use XYZ plots Script to Optimize Parameters and Get the Most Out of your Model!

This video tutorial walks you through how to use the XYZ plot Script in Automatic 1111 and provides a simple workflow that can help you find the optimal values of Sampling Steps, CFG scale, and Sampling Methods for the model you are using. I would recommend to do this when you first start working with a new model or checkpoint.

Be wary of '.ckpt' files that you download online. It may contain malicious scripts inside. Do NOT open the '.ckpt' file unless you know what's inside. ***If you enjoy my videos, consider supporting me on Ko-fi*** https://ko-fi.com/keyboardalchemist
