ComfyDeploy: How Stable-Diffusion-temperature-settings works in ComfyUI?

What is Stable-Diffusion-temperature-settings?

Provides the ability to set the temperature for both UNET and CLIP. For ComfyUI.

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for Stable-Diffusion-temperature-settings and select it
  5. Close the build step dialig and then click on the "Save" button to rebuild the machine

Stable-Diffusion-temperature-settings

Provides the ability to set the temperature for both UNET and CLIP. For ComfyUI.

I also added a togglable function compatible with SD 1.x models and SDXL/Turbo which helps to preserve quality weither it is for downscaling or upscaling.

Usage

Like any other model patch:

CLIP temperature at 0.75, 1 and 1.25. Prompt "a bio-organic living plant spaceship"

combined_image_new

The temperature scaling option allows to avoid smudged details during an upscale:

Without / with

234523423

This does not include tiled upscales since the tiling uses smaller latents as the workaround for this well known issue.

Using SDXL, 512x512, 256x256, 128x128 without / with modification on the U-Net:

Using SD v1-5-pruned-emaonly:

This is one of my first tests and I only display it as the proof of concept, exposing the possibility to fix the scaling issues with the U-Net.

  • Lower temperature applied to all layers except input 1 and 2, output 9, 10 and 11 which were ignored.
  • At 0.71.
  • Only self-attention
  • Resolution at 1024*512

Pro tip:

Did you know that my first activity is to write creative model merging functions?

While the code is too much of a mess to be shared, I do expose and share my models. You can find them in this gallery! 😁
