ModelSamplingSD3 - ComfyUI Built-in Node Documentation

The ModelSamplingSD3 node applies Stable Diffusion 3 sampling parameters to a model. It modifies the model’s sampling behavior by adjusting the shift parameter, which controls the sampling distribution characteristics. The node creates a modified copy of the input model with the specified sampling configuration applied.

Inputs

`model`	The input model to apply SD3 sampling parameters to	MODEL	Yes	-
`shift`	Controls the sampling shift parameter (default: 3.0)	FLOAT	Yes	0.0 - 100.0

Outputs
