# HyperTile - ComfyUI Built-in Node Documentation

> HyperTile applies a tiling technique to the attention mechanism inside diffusion models to reduce memory usage during image generation.

HyperTile applies a tiling technique to the attention mechanism inside diffusion models to reduce memory usage during image generation. It splits the latent space into smaller tiles, processes the attention for each tile separately, and then reassembles the results. This makes it possible to work with larger image sizes without running out of memory.

## Inputs

| Parameter     | Description                                                                                                                                                      | Data Type | Required | Range        |
| ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------ |
| `model`       | The diffusion model to apply the HyperTile optimization to                                                                                                       | MODEL     | Yes      | -            |
| `tile_size`   | The target tile size for processing (default: 256). Internally, the value is clamped to a minimum of 32 and then divided by 8 to obtain the effective tile size. | INT       | Yes      | 1 - 2048     |
| `swap_size`   | Controls how the tiles are rearranged during processing to improve efficiency. Larger values allow more variation in tile sizes (default: 2)                     | INT       | Yes      | 1 - 128      |
| `max_depth`   | The maximum depth level (resolution scale) to apply tiling. A value of 0 applies tiling only at the highest resolution (default: 0)                              | INT       | Yes      | 0 - 10       |
| `scale_depth` | When enabled, the tile size is scaled proportionally at deeper depth levels. This can help maintain quality at lower resolutions (default: False)                | BOOLEAN   | Yes      | True / False |

Note: `tile_size`, `swap_size`, `max_depth`, and `scale_depth` are marked as advanced inputs, so they are only shown when advanced options are enabled in the interface.

## Outputs

| Output Name | Description                                            | Data Type |
| ----------- | ------------------------------------------------------ | --------- |
| `model`     | The modified model with HyperTile optimization applied | MODEL     |
