SwarmUI-SkimmedCFG

A SwarmUI extension that adds parameters for Extraltodeus's Skimmed_CFG custom nodes to the generate tab, a powerful anti-burn allowing much higher CFG scales for latent diffusion models.

Changelog

25 May 2025

Make sure you update SwarmUI to at least v0.9.6.1 before updating to this version of SkimmedCFG as it uses new APIs

• Fixed code calling internal T2IParamInput.ValuesInput field that will be removed in a future SwarmUI update

19 October 2024

• Initial Release

Installation (Simple)

1. Update SwarmUI first, if you have an old version this extension may not work
2. In SwarmUI go to the Server/Extensions tab
3. Find SkimmedCFG in the list and click the 'Install' button
4. Refresh the page and go back to the generate tab, if you see the parameters then the required ComfyUI dependencies are installed and you can start using the extension, otherwise continue below.
5. If the Skimmed_CFG custom node is not installed in the backend an install button will be shown in the parameter group, install it and follow the prompts

6. Now the parameters should appear and you are good to go

Installation (Advanced)

1. Update SwarmUI first, if you have an old version this extension may not work
2. Shutdown SwarmUI
3. Open a cmd/terminal window in SwarmUI\src\Extensions
4. Run git clone https://github.com/Quaggles/SwarmUI-SkimmedCFG.git
5. Run SwarmUI\update-windows.bat or SwarmUI\update-linuxmac.sh to recompile SwarmUI
6. Launch SwarmUI and follow on from Step 4 of Installation (Simple)

Updating

1. Update SwarmUI first, if you have an old version this extension may not work
2. In SwarmUI go to the Server/Extensions tab
3. Click the update button for 'SkimmedCFGExtension'

Usage

The extension has 6 modes, one for each custom nodes:

• Base (Skimmed CFG)
• Linear Interpolation
• Linear Interpolation Dual Scales
• Replace
• Timed Flip
• Difference CFG

I'd recommend first experimenting by:

• Using the 'Base' Mode
• Setting the SkimmingCFG to 3-4 (Higher for more saturation, lower if it's burning too much)
• Setting the SwarmUI CFG Scale to something like 7-12, try increasing this while fiddling with SkimmingCFG (If you need to go higher than 20 you can use the [SkimmedCFG] Override Core CFG parameter)

This should allow you to gain the benefits of high CFG scale without the typical burn in effects. Read through the SkimmedCFG readme for examples and the parameter tooltips to understand what they do (Some parameters only work with certain modes are only visible if you enable Display Advanced Options in SwarmUI).
