    ### Input Schema

    <ParamField body="image_url" type="string" required>
      Input image url.
    </ParamField>

    <ParamField body="num_inference_steps" type="integer" default="10">
      Number of denoising steps. Defaults to `10`. The higher the number, the more accurate the result, but the slower the inference. Default value: `10`

    <ParamField body="ensemble_size" type="integer" default="10">
      Number of predictions to average over. Defaults to `10`. The higher the number, the more accurate the result, but the slower the inference. Default value: `10`

      Range: `2` to `50`
    </ParamField>

    <ParamField body="processing_res" type="integer" default="0">
      Maximum processing resolution. Defaults `0` which means it uses the size of the input image.
