- **Ease of Use:** Simple CLI and Python API for quick and straightforward model exporting.

### Key Features of Export Mode

Here are some of the standout functionalities:

- **One-Click Export:** Simple commands for exporting to different formats.
- **Batch Export:** Export batched-inference capable models.
- **Optimized Inference:** Exported models are optimized for quicker inference times.
- **Tutorial Videos:** In-depth guides and tutorials for a smooth exporting experience.

!!! tip "Tip"

    * Export to ONNX or OpenVINO for up to 3x CPU speedup.
    * Export to TensorRT for up to 5x GPU speedup.

## Usage Examples

Export a YOLOv8n model to a different format like ONNX or TensorRT. See Arguments section below for a full list of export arguments.

!!! example ""

    === "Python"

        ```python
        from ultralytics import YOLO

        # Load a model
        model = YOLO('yolov8n.pt')  # load an official model
        model = YOLO('path/to/best.pt')  # load a custom trained model

        # Export the model
        model.export(format='onnx')
        ```
    === "CLI"

        ```bash
        yolo export model=yolov8n.pt format=onnx  # export official model
        yolo export model=path/to/best.pt format=onnx  # export custom trained model
        ```

## Arguments

Export settings for YOLO models refer to the various configurations and options used to save or export the model for use in other environments or platforms. These settings can affect the model's performance, size, and compatibility with different systems. Some common YOLO export settings include the format of the exported model file (e.g. ONNX, TensorFlow SavedModel), the device on which the model will be run (e.g. CPU, GPU), and the presence of additional features such as masks or multiple labels per box. Other factors that may affect the export process include the specific task the model is being used for and the requirements or constraints of the target environment or platform. It is important to carefully consider and configure these settings to ensure that the exported model is optimized for the intended use case and can be used effectively in the target environment.
