# SamplerLCM - ComfyUI Built-in Node Documentation

> The SamplerLCM node provides an LCM (Latent Consistency Model) sampler with tunable per-step noise parameters.

The SamplerLCM node provides an LCM (Latent Consistency Model) sampler with tunable per-step noise parameters. It lets you control the noise applied at each step of the sampling process; `s_noise` is a multiplier on the model's training noise scale.

## 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 noise 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
