ModelSamplingLTXV - ComfyUI Built-in Node Documentation

The ModelSamplingLTXV node applies advanced sampling parameters to a model based on token count. It calculates a shift value using a linear interpolation between base and maximum shift values, with the calculation depending on the number of tokens in the input latent. The node then creates a specialized model sampling configuration and applies it to the input model.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The input model to apply sampling parameters to	MODEL	Yes	-
`max_shift`	The maximum shift value used in the linear interpolation calculation (default: 2.05)	FLOAT	Yes	0.0 to 100.0
`base_shift`	The base shift value used in the linear interpolation calculation (default: 0.95)	FLOAT	Yes	0.0 to 100.0
`latent`	Optional latent input used to determine the token count for the shift calculation. If not provided, a default token count of 4096 is used	LATENT	No	-
