# Stable-Diffusion-temperature-settings
Provides the ability to set the temperature for both UNET and CLIP. For ComfyUI.

## The nodes

## Specifities

- The CLIP patch ignores the connections and patches the model within the memory. Simply disconnecting it does not revert the behavior. To revert to default behavior set it at 1 or reload the model without the node connected. It is the only node ignoring the connections and does not modify anything but the connected CLIP model.
- For SD1 and SDXL nodes: settings the temperature at zero will use a dynamic scale proportional to the resolution. It is good for lower resolutions but not on point for higher.

## Usage

Like any other model patch:

## Requirements:

Requires pytorch 2.3 and above.

## Interesting side-effect:

Changing the UNET temperature allows to obtain better results a different resolutions. While it is not the full solution to the scaling issues of Stable Diffusion, it is a strong clue indicating the possibility to sample at much higher (or lower) resolutions.

### Here using SDXL at a resolution of 328x328. First row temperature at 1, second row using dynamic scaled attention:

### Non cherry-picked SD v1-5-pruned-emaonly at 512*1024, first row with the dynamic scale, second without:

### Lost workflows for these as they were done during testing but proves the idea of making SD better at different resolutions:

The temperature was applied to all layers except input 1 and 2, output 9, 10 and 11. At 0.71. Only on self-attention.

### Other simple example with SD 1.5, with/without are obvious enough (these two are workflows):
