SamplerEulerAncestral - ComfyUI Built-in Node Documentation

The SamplerEulerAncestral node creates an Euler Ancestral sampler for generating images. This sampler uses a specific mathematical approach that combines Euler integration with ancestral sampling techniques to produce image variations. The node allows you to configure the sampling behavior by adjusting parameters that control the randomness and step size during the generation process.

Inputs

Parameter	Description	Data Type	Required	Range
`eta`	Controls the step size and stochasticity of the sampling process (default: 1.0). This is an advanced parameter.	FLOAT	Yes	0.0 - 100.0
`s_noise`	Controls the amount of noise added during sampling (default: 1.0). This is an advanced parameter.	FLOAT	Yes	0.0 - 100.0

Outputs

Output Name	Description	Data Type
`sampler`	Returns a configured Euler Ancestral sampler that can be used in the sampling pipeline.	SAMPLER
