SamplerLCM - ComfyUI Built-in Node Documentation

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
