# LoadDA3Model - ComfyUI Built-in Node Documentation

> Complete documentation for the LoadDA3Model node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node loads a Depth Anything 3 model from a file, preparing it for use in depth estimation tasks. It allows you to select the model file and optionally specify the numerical precision (data type) for the model's weights.

## Inputs

| Parameter      | Description                                                                                                                                 | Data Type | Required | Range                                                             |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------------------- |
| `model_name`   | The name of the Depth Anything 3 model file to load.                                                                                        | STRING    | Yes      | List of available model files in the `geometry_estimation` folder |
| `weight_dtype` | The numerical precision (data type) for the model's weights. The "default" option uses the model's original precision. (default: "default") | STRING    | No       | `"default"`<br />`"fp16"`<br />`"bf16"`<br />`"fp32"`             |

## Outputs

| Output Name | Description                                                                     | Data Type  |
| ----------- | ------------------------------------------------------------------------------- | ---------- |
| `DA3_MODEL` | The loaded Depth Anything 3 model, ready for use in depth estimation workflows. | DA3\_MODEL |
