While building this web app, we will cover the basics of working with and understanding OpenAI’s ChatGPT, including accessing the OpenAI API, the GPT models OpenAI offers, the create chat completion endpoint and tokens, among other topics.

As the starting point for our project, we use the “Hello, World!” web app with Next.js and Tailwind CSS that we built in an earlier lesson: Setting up a “Hello, World!” app with Next.js and Tailwind CSS.

If you want to get started right away, the project files are also available as a public repository on GitHub (released under the MIT License): https://github.com/david-j-wu/hello-world-nextjs-tailwind-css

The lesson itself is short and should be able to be completed in as little as 15-30 minutes if you have prior experience with Node.js and JavaScript libraries like Next.js and React.js.
