# ModelMergeSubtract - ComfyUI Built-in Node Documentation

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

This node is designed for advanced model merging operations, specifically to subtract the parameters of one model from another based on a specified multiplier. It enables the customization of model behaviors by adjusting the influence of one model's parameters over another, facilitating the creation of new, hybrid models.

## Inputs

| Parameter    | Data Type | Description                                                                               |
| ------------ | --------- | ----------------------------------------------------------------------------------------- |
| `model1`     | `MODEL`   | The base model from which parameters will be subtracted.                                  |
| `model2`     | `MODEL`   | The model whose parameters will be subtracted from the base model.                        |
| `multiplier` | `FLOAT`   | A floating-point value that scales the subtraction effect on the base model's parameters. |

## Outputs

| Parameter | Data Type | Description                                                                                               |
| --------- | --------- | --------------------------------------------------------------------------------------------------------- |
| `model`   | MODEL     | The resulting model after subtracting the parameters of one model from another, scaled by the multiplier. |
