# ModelMergeKrea2 - ComfyUI Built-in Node Documentation

> Complete documentation for the ModelMergeKrea2 node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node merges two models by blending their internal components at a fine-grained level, allowing you to control how much of each model's specific parts influence the final result. It works by taking two input models and applying separate blend ratios to different sections of their architecture.

## Inputs

| Parameter                        | Description                                                           | Data Type | Required | Range                   |
| -------------------------------- | --------------------------------------------------------------------- | --------- | -------- | ----------------------- |
| `model1`                         | The first model to merge                                              | MODEL     | Yes      | -                       |
| `model2`                         | The second model to merge                                             | MODEL     | Yes      | -                       |
| `first.`                         | Blend ratio for the first layer block (default: 1.0)                  | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `tmlp.`                          | Blend ratio for the time MLP block (default: 1.0)                     | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtmlp.`                        | Blend ratio for the text MLP block (default: 1.0)                     | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `tproj.`                         | Blend ratio for the time projection block (default: 1.0)              | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtfusion.layerwise_blocks.0.`  | Blend ratio for the first text fusion layerwise block (default: 1.0)  | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtfusion.layerwise_blocks.1.`  | Blend ratio for the second text fusion layerwise block (default: 1.0) | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtfusion.projector.`           | Blend ratio for the text fusion projector block (default: 1.0)        | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtfusion.refiner_blocks.0.`    | Blend ratio for the first text fusion refiner block (default: 1.0)    | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `txtfusion.refiner_blocks.1.`    | Blend ratio for the second text fusion refiner block (default: 1.0)   | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `blocks.0.` through `blocks.27.` | Blend ratio for each of the 28 main blocks (default: 1.0)             | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |
| `last.`                          | Blend ratio for the last block (default: 1.0)                         | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |

Each blend ratio controls how much of `model2` is used for that specific component, where 0.0 means use only `model1`, 1.0 means use only `model2`, and values in between create a weighted blend.

## Outputs

| Output Name | Description                                                                                     | Data Type |
| ----------- | ----------------------------------------------------------------------------------------------- | --------- |
| `MODEL`     | The merged model resulting from blending the two input models according to the specified ratios | MODEL     |
