# ConditioningConcat - ComfyUI Built-in Node Documentation

> The ConditioningConcat node is designed to concatenate conditioning vectors, specifically merging the 'conditioningfrom' vector into the 'conditioningto' vector.

The ConditioningConcat node is designed to concatenate conditioning vectors, specifically merging the 'conditioning\_from' vector into the 'conditioning\_to' vector. This operation is fundamental in scenarios where the conditioning information from two sources needs to be combined into a single, unified representation.

## Inputs

| Parameter           | Description                                                                                                                                                                                           | Comfy dtype    |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- |
| `conditioning_to`   | Represents the primary set of conditioning vectors to which the 'conditioning\_from' vectors will be concatenated. It serves as the base for the concatenation process.                               | `CONDITIONING` |
| `conditioning_from` | Consists of conditioning vectors that are to be concatenated to the 'conditioning\_to' vectors. This parameter allows for additional conditioning information to be integrated into the existing set. | `CONDITIONING` |

## Outputs

| Parameter      | Description                                                                                                                                                | Comfy dtype    |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- |
| `conditioning` | The output is a unified set of conditioning vectors, resulting from the concatenation of 'conditioning\_from' vectors into the 'conditioning\_to' vectors. | `CONDITIONING` |
