Create Your Own Custom Nodes in ComfyUI

Video Description

Learn how to write custom nodes from scratch in ComfyUI using Python. Hello everyone, in this video tutorial, I show you step-by-step how to create your own custom nodes for ComfyUI. We start by looking at the example node provided by default and understanding how ComfyUI loads and interprets custom nodes. We then build our own node from scratch, including defining the inputs, outputs, and processing function. Our custom node combines the positive and negative prompt encoders into one. Finally, we connect our node to sample an image, showing that it works! Useful if you want to customize ComfyUI and streamline your workflows for Stable Diffusion image generation.
