=============================================================================================== OpenVINO™ Test Drive

.. meta:: :description: See how to test your models with OpenVINO, using a simple graphic interface of Test Drive.

OpenVINO™ Test Drive is a cross-platform graphic user interface application for running and testing AI models, both generative and vision based. It can run directly on your computer or on edge devices using OpenVINO™ Runtime <https://github.com/openvinotoolkit/openvino>__.

OpenVINO™ Test Drive is developed under the openvino_testdrive repository <https://github.com/openvinotoolkit/openvino_testdrive>__.

Use OpenVINO™ Test Drive to:

• Chat with LLMs and evaluate model performance on your computer or edge device;
• Experiment with different text prompts to generate images, using Stable Diffusion and Stable DiffusionXL models;
• Transcribe speech from video, using Whisper models, including generation of timestamps;
• Run inference of models trained by Geti™ and visualize the results.

Installation (Windows) ###############################################################################################

.. important::

For Intel® NPU, use the latest available version of Intel® NPU Driver <https://www.intel.com/content/www/us/en/download/794734/intel-npu-driver-windows.html>__.

1. Download the latest archive from the release repository <https://storage.openvinotoolkit.org/repositories/openvino_testdrive/packages>__. To verify the integrity of the downloaded package, use the SHA-256 file attached.

2. Extract the zip file and run the MSIX installation package. Click the Install button to proceed.

3. Launch OpenVINO™ Test Drive, clicking the application name in the Windows app list.

Quick start ###############################################################################################

When starting the application, you can import an LLM model from Hugging Face Hub or upload a Geti™ model from a local drive.

Text generation and LLM performance evaluation +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1. Find a model on Hugging Face <https://huggingface.co/>__ and import it.

2. Select the speech-to-text LLM from the My models section, and upload a video for transcription.

   .. image:: ../../../assets/images/TestDrive_ts_video.gif :align: center :alt: importing a visual language model for image analysis

   You can search for words in the transcript or download it.

3. Use the Performance metrics tab to get performance metrics of the LLM on your computer or an edge device.

Image generation with LLMs +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1. Import an image generation LLM from a predefined set of popular models or from Hugging Face <https://huggingface.co/>__, using Import model -> Hugging Face.

2. Select the LLM from the My models section and start the chat to generate an image. You can export the model by clicking the Export model button.

   .. image:: ../../../assets/images/TestDrive_image_generation.gif :align: center :alt: image generation with a chosen LLM

   You can download the generated image.

3. Use the Performance metrics tab to get performance metrics of the LLM on your computer or an edge device.

Inference of models trained with Intel® Geti™ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1. Download the deployment code for a model in the OpenVINO IR format trained by Geti™ (refer to the Geti™ documentation <https://docs.geti.intel.com>__ for more details).

   .. image:: ../../../assets/images/TestDrive_geti_download.gif :align: center :alt: verifying llm performance in test drive

2. Import the deployment code into OpenVINO™ Test Drive, using the Import model and then Local disk buttons.

3. Use the Live inference tab to run and visualize results of inference of individual images.

4. For batch inference, use the Batch inference tab and provide paths to the folder with input images, as well as one for batch inference results. You can do so by filling out the Source folder and Destination folder fields. Click Start to start batch inference.

Build the Application ###############################################################################################

1. Make sure you Install flutter SDK <https://docs.flutter.dev/get-started/install>__ and all its platform-specific dependencies.

2. Build the bindings and place them in the ./bindings folder.

   OpenVINO™ Test Drive uses bindings to OpenVINO™ GenAI <https://github.com/openvinotoolkit/openvino.genai>__ and OpenVINO™ Model API <https://github.com/openvinotoolkit/model_api>, which are located in the ./openvino_bindings folder. Refer to the GitHub page <https://github.com/openvinotoolkit/openvino_testdrive/blob/main/openvino_bindings/> for more details.

3. Start the application, using the following command:

   .. code-block:: console

   flutter run
