 In this section, we provide a simple example script that integrates Azure OpenAI's `computer-use-preview` model with [Playwright](https://playwright.dev/) to automate basic browser interactions. Combining the model with [Playwright](https://playwright.dev/) allows the model to see the browser screen, make decisions, and perform actions like clicking, typing, and navigating websites. You should exercise caution when running this example code. This code is designed to be run locally but should only be executed in a test environment. Use a human to confirm decisions and don't give the model access to sensitive data.
