 | `imgsz`   | `640`         | The input image size for the model. Can be a single integer for square images or a tuple `(width, height)` for non-square, e.g., `(640, 480)`.                                                          |
 | `half`    | `False`       | Enables FP16 (half-precision) inference, reducing memory usage and possibly increasing speed on compatible hardware. Use `half=True` to enable.                                                         |
 | `int8`    | `False`       | Activates INT8 quantization for further optimized performance on supported devices, especially useful for edge devices. Set `int8=True` to use.                                                         |
-| `device`  | `None`        | Defines the computation device(s) for benchmarking, such as `"cpu"`, `"cuda:0"`, or a list of devices like `"cuda:0,1"` for multi-GPU setups.                                                           |

 | `verbose` | `False`       | Controls the level of detail in logging output. A boolean value; set `verbose=True` for detailed logs or a float for thresholding errors.                                                               |
