ComfyUI Tutorial Series: Ep10 - 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 You’ll learn how to install missing nodes, find alternatives when nodes cause errors, and uninstall outdated ones.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.

How to install Flux GGUF versions:
Make sure ComfyUI is updated

Go to Manager - Custom Nodes Manager
Search for GGUF
Install the node: ComfyUI-GGUF

Get one of the Flux Dev Models (recommended to use Q5_K_M or larger for the best results)
Place it in the unet folder ..ComfyUI/models/unet

Or get one of the Flux Schnell Models (faster and smaller)
Place it in the unet folder ..ComfyUI/models/unet

Place it in the clip folder ..ComfyUI\models\clip

Get one of the T5 encoders (recommended to use Q5_K_M or larger for the best results)
Place it in the clip folder ..ComfyUI\models\clip

Place it in the vae folder ..ComfyUI\models\vae

You add the Unet Loader (GGUF) to load one of the flux gguf models
You add DualClipLoader (GGUF) to add clip_l and one of the T5 encoders and change type to flux

Schnell needs 4 steps in ksampler, and Dev needs 20 steps.
If you are using a workflow with the art styles check Episode 07 to learn how to set up the node and config file.

Love your videos, What is the best inpainting on comfyui (not for flux). Are you going to make a video of it?

[atahanacik]

the blur thing is about number of steps, for illustrations the image is kind of complete around 15 steps and at 20 it is iterating to different visual. You can either try 15 or 25. After 25 it may again go blurry and you are again getting a completed image around 40 steps. Fyki =)

[thibaudherbert]

nice ! What about the modelsamplingflux ? You don't use max shift /base shift parameters ?

[iman-ez]

hey tnx for the greate tutorial, for the blury images you guys can set the sampler to euler and scheduler to beta

[longsyee]

Is there any style csv for flux just like for SDXL? Looking Forward

[Deathshot_Official]

I get same error, still trying to find a solution. Great work bro

[eukaryote-prime]

Are you familiar with the hyper-sd Lora’s for flux that were recently released?

I tried to set it up but obviously don’t know enough because I just got noise

[NicolasLuthy]

Hi I Hope you can help me, I currently run comfyui through colab. However after installing all as in your video I only have SDXL or SD* in my dual clip loader.. There is no FLUX😪 Any idea why?

[marshallodom]

Where can I get a copy of the workslow without going to discurd?

[liquidmind]

helo friend!! how can i add a LORA flux loader, so i can use my custom flux lora models?

[thepoonhound]

whats the difference between the models flux1-dev-Q5_K_S.gguf flux1-dev-Q5_1.gguf flux1-dev-Q5_0.gguf like what does the k_s and 1 and 0 mean

[andreizdetovetchi]

Ce placa video folosesti de ai vitezele alea? :)

[mesandz]

Got here out of curiosity… could be speaking another language not on earth to me… but interested in learning.

I tried Flux GGUF last night and it took 10 minutes to render a 1024x1024 image compared to the 10 seconds it takes in SDXL. My RTX 3070 days are numbered lol
