The BetaSamplingScheduler node generates a sequence of noise levels (sigmas) for the sampling process using a beta scheduling algorithm. It takes a model and configuration parameters to create a customized noise schedule that controls the denoising process during image generation. This scheduler allows fine-tuning of the noise reduction trajectory through alpha and beta parameters.

Inputs

Parameter	Data Type	Input Type	Default	Range	Description
`model`	MODEL	Required	-	-	The model used for sampling, which provides the model sampling object
`steps`	INT	Required	20	1-10000	The number of sampling steps to generate sigmas for
`alpha`	FLOAT	Required	0.6	0.0-50.0	Alpha parameter for the beta scheduler, controlling the scheduling curve
`beta`	FLOAT	Required	0.6	0.0-50.0	Beta parameter for the beta scheduler, controlling the scheduling curve

Outputs

Output Name	Data Type	Description
