ModelSamplingAuraFlow - ComfyUI Built-in Node Documentation

The ModelSamplingAuraFlow node applies a specialized sampling configuration to diffusion models, specifically designed for AuraFlow model architectures.

The ModelSamplingAuraFlow node applies a specialized sampling configuration to diffusion models, specifically designed for AuraFlow model architectures. It modifies the model’s sampling behavior by applying a shift value that adjusts the sampling distribution. This node inherits from the SD3 model sampling framework and provides fine control over the sampling process.

Inputs

Parameter	Description	Data Type	Required	Range
model	The diffusion model to apply the AuraFlow sampling configuration to	MODEL	Yes	-
shift	The shift value to apply to the sampling distribution (default: 1.73, step: 0.01)	FLOAT	Yes	0.0 - 100.0
sampling	The sampling mode used when patching the model (default: “flow”). Marked as an advanced option.	COMBO	No	”flow" "img_to_img_velocity”

Outputs

Output Name	Description	Data Type
model	The modified model with AuraFlow sampling configuration applied	MODEL
