# SamplerLCM - ComfyUI Built-in Node Documentation

> Complete documentation for the SamplerLCM node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The SamplerLCM node provides an LCM (Latent Consistency Model) sampler with tunable per-step noise parameters. It allows you to control the noise applied at each sampling step, enabling fine-grained adjustment of the sampling process.

## Inputs

| Parameter        | Description                                                                                                          | Data Type | Required | Range                    |
| ---------------- | -------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------ |
| `s_noise`        | Per-step noise multiplier at the first step. A value of 1.0 matches the model's training noise scale. (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` | Clamps the per-step noise to within +/- N standard deviations. A value of 0 disables clamping. (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   |
