Developing Apps with GPT-4 and ChatGPT

Chapter 2. A Deep Dive into the GPT-4 and ChatGPT APIs

This chapter examines the GPT-4 and ChatGPT APIs in detail. The goal of this chapter is to give you a solid understanding of the use of these APIs so that you can effectively integrate them into your Python applications. By the end of this chapter, you will be well equipped to use these APIs and exploit their powerful capabilities in your own development projects.

We’ll start with an introduction to the OpenAI Playground. This will allow you to get a better understanding of the models before writing any code. Next, we will look at the OpenAI Python library. This includes the login information and a simple “Hello World” example. We will then cover the process of creating and sending requests to the APIs. We will also look at how to manage API responses. This will ensure that you know how to interpret the data returned by these APIs. In addition, this chapter will cover considerations such as security best practices and cost management.

As we progress, you will gain practical knowledge that will be very useful in your journey as a Python developer working with GPT-4 and ChatGPT. All the Python code included in this chapter is available in the book’s GitHub repository.
