The APG (Adaptive Projected Guidance) node modifies the sampling process by adjusting how guidance is applied during diffusion. It separates the guidance vector into parallel and orthogonal components relative to the conditional output, allowing for more controlled image generation. The node provides parameters to scale the guidance, normalize its magnitude, and apply momentum for smoother transitions between diffusion steps.

Inputs

Parameter	Data Type	Input Type	Default	Range	Description
model	MODEL	Required	-	-	The diffusion model to apply adaptive projected guidance to
eta	FLOAT	Required	1.0	-10.0 to 10.0	Controls the scale of the parallel guidance vector. Default CFG behavior at a setting of 1.
norm_threshold	FLOAT	Required	5.0	0.0 to 50.0	Normalize guidance vector to this value, normalization disable at a setting of 0.
momentum	FLOAT	Required	0.0	-5.0 to 1.0	Controls a running average of guidance during diffusion, disabled at a setting of 0.

Outputs

Output Name	Data Type	Description
model	MODEL	Returns the modified model with adaptive projected guidance applied to its sampling process
