ComfyUI Tutorial Series: Ep010 - Flux GGUF and Custom Nodes

Welcome to the 10th episode of our ComfyUI tutorial series!

In this episode, we'll cover how to manage custom nodes in ComfyUI -adding, removing, and installing any missing ones. We'll also explore Flux GGUF, showing you how to install and use it within ComfyUI.

We’ll start by reviewing some recent updates, including fixes and new features, and then move on to managing custom nodes. You’ll learn how to install missing nodes, find alternatives when nodes cause errors, and uninstall outdated ones. Additionally, I’ll guide you through setting up Flux GGUF, including selecting the best models for your needs and optimizing performance.

We’ll also touch on practical aspects like using alternative nodes, troubleshooting common issues, and creating efficient workflows. By the end of this episode, you’ll have a deeper understanding of how to work with custom nodes and Flux GGUF, helping you make the most of ComfyUI.
