The LatentConcat node combines two latent samples by joining them together along a chosen dimension. It takes two latent inputs and concatenates them along the x, y, or t axis, with the option to control which sample comes first. The node automatically adjusts the batch size of the second input to match the first before performing the concatenation.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `samples1` | The first latent sample to concatenate | LATENT | Yes | - |
| `samples2` | The second latent sample to concatenate | LATENT | Yes | - |
| `dim` | The dimension along which to concatenate the latent samples. Positive values (x, y, t) place samples1 before samples2 in the result. Negative values (-x, -y, -t) place samples2 before samples1. The dimension mapping is: x = width, y = height, t = time/frames | COMBO | Yes | `"x"`<br>`"-x"`<br>`"y"`<br>`"-y"`<br>`"t"`<br>`"-t"` |

**Note:** The second latent sample (`samples2`) is automatically adjusted to match the batch size of the first latent sample (`samples1`) before concatenation.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `output` | The concatenated latent samples resulting from combining the two input samples along the specified dimension | LATENT |
