 As an AI language model enthusiast, I often find myself alarmed by the way sensitive data is carelessly handled in various applications. While the excitement around GPT is understandable, the improper handling of sensitive information poses significant challenges for administrators and security professionals managing servers rented by clients. This document aims to provide best practices for securely implementing GPT in web applications to prevent security vulnerabilities and protect sensitive data.

 With AJAX, you can asynchronously send data to and retrieve data from the server without exposing sensitive information in the browser console.

 ## Choosing the Appropriate API Endpoint
-When implementing GPT, it's crucial to select the appropriate API endpoint based on your specific use case. OpenAI provides various endpoints for different purposes. Here's a list of the current OpenAI endpoints:
