# SamplerLCM - ComfyUI Built-in Node Documentation

> This node provides an LCM (Latent Consistency Model) sampler with adjustable per-step noise.

This node provides an LCM (Latent Consistency Model) sampler with adjustable per-step noise. It lets you control how much noise is applied during sampling: `s_noise` acts as a multiplier on the model's training noise scale, and the noise level can vary from the first step to the last step. The configured sampler can then be plugged into a sampling workflow.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `s_noise` | Per-step noise multiplier at the first step (1.0 = match training). Default: 1.0. | FLOAT | Yes | 0.0 to 64.0 (step: 0.01) |
| `s_noise_end` | Per-step noise multiplier at the last step. Set equal to `s_noise` for a constant schedule. Default: 1.0. | FLOAT | Yes | 0.0 to 64.0 (step: 0.01) |
| `noise_clip_std` | Clamp per-step noise to +/- N\*std. 0 disables. Default: 0.0. | FLOAT | Yes | 0.0 to 10.0 (step: 0.01) |

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `SAMPLER` | The configured LCM sampler object, ready to be used in a sampling workflow. | SAMPLER |
