ModelComputeDtype - ComfyUI Built-in Node Documentation - ComfyUI

The ModelComputeDtype node changes the computational data type (precision) used by a model during processing. It creates a copy of the input model and applies the selected precision setting, which can help optimize memory usage and performance depending on your hardware. This is useful for debugging and testing different precision configurations.

Inputs

Parameter	Description	Data Type	Required	Range
