RandomNoise - ComfyUI Built-in Node Documentation - ComfyUI

The RandomNoise node creates a noise generator based on a seed value for use during the sampling process. The same seed always produces the same noise pattern, allowing for consistent, reproducible results across multiple runs. Samplers use the generated noise when processing latent images.

Inputs

Parameter	Description	Data Type	Required	Range
`noise_seed`	The seed value used to generate the random noise pattern (default: 0). The same seed always produces the same noise output. This input includes a control-after-generate option to automatically update the seed after each generation.	INT	Yes	0 to 18446744073709551615

Outputs

Output Name	Description	Data Type
`noise`	A noise object that generates random noise for latent samples based on the provided seed value. Used by samplers during the sampling process.	NOISE
