Create a ChatGPT Plugin from Scratch | Step-by-Step Tutorial
ChatGPT plug-ins are here! One of the newest features available with GPT-4, plugins effectively allow you to get out to the internet to retrieve real-time information from the provider. Plugins are currently available for a handful of companies like Expedia, Kayak or Wolfram, but even more exciting is that you can create your own! And that’s the focus of this video.
In this hands-on tutorial, I’ll walk you step-by-step through how to create a ChatGPT plugin from scratch (but with code provided if you’d like it). Using Replit, we’ll create a Flask API that retrieves stock information from an external API (Alpha Vantage). Then we’ll test it locally before deploying it to a public endpoint (also hosted in Replit). Finally, we’ll install the plugin from the ChatGPT interface and see it in action.
