[Feature]: Temporal Score Rescaling - temperature sampling for diffusion - sharpness control #10214
Description
Feature Idea
Temporal score rescaling is a training-free technique to steer the sampling diversity of diffusion and flow models. It works by rescaling the model's output depending on the timestep and the "temperature" parameter.
The end result is basically the detail control lora, yet can be applied training-free to models such as Qwen.
Auxiliary parameter of sigma controls how early this will steer the diffusion process.
The closest node with output altering functionality in vanilla comfy is TCFG, so it will likely be just a similar node.
