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

ParameterData TypeRequiredRangeDescription
modelMODELYes-The model used for sampling, which provides the model sampling object
stepsINTYes1 to 10000The number of sampling steps to generate sigmas for (default: 20)
alphaFLOATYes0.0 to 50.0Alpha parameter for the beta scheduler, controlling the scheduling curve (default: 0.6)
betaFLOATYes0.0 to 50.0Beta parameter for the beta scheduler, controlling the scheduling curve (default: 0.6)

Outputs

Output NameData TypeDescription
SIGMASSIGMASA sequence of noise levels (sigmas) used for the sampling process
