SamplerEulerAncestral - ComfyUI Built-in Node Documentation

The SamplerEulerAncestral node creates an Euler Ancestral sampler that can be used during image generation.

The SamplerEulerAncestral node creates an Euler Ancestral sampler that can be used during image generation. This sampler combines Euler integration with ancestral sampling, which adds a degree of randomness at each step to produce varied results. The node lets you adjust how much randomness is applied through its settings.

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
