# 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   |
