ExponentialScheduler - ComfyUI Built-in Node Documentation

The ExponentialScheduler node is designed to generate a sequence of sigma values following an exponential schedule for diffusion sampling processes. It provides a customizable approach to control the noise levels applied at each step of the diffusion process, allowing for fine-tuning of the sampling behavior.

Inputs

Parameter	Description	Data Type
`steps`	Specifies the number of steps in the diffusion process. It influences the length of the generated sigma sequence and thus the granularity of the noise application.	INT
`sigma_max`	Defines the maximum sigma value, setting the upper limit of noise intensity in the diffusion process. It plays a crucial role in determining the range of noise levels applied.	FLOAT
`sigma_min`	Sets the minimum sigma value, establishing the lower boundary of noise intensity. This parameter helps in fine-tuning the starting point of the noise application.	FLOAT

Outputs

Parameter	Description	Data Type
`sigmas`	A sequence of sigma values generated according to the exponential schedule. These values are used to control the noise levels at each step of the diffusion process.	SIGMAS
