Building a Chatbot with OpenAI, Shiny, & R - Part 1: Use GPT-4 with OpenAI API in R

In this tutorial, you'll learn how to query the OpenAI API from R using the {httr2} package. We'll focus on the chat capabilities of the API and build a function to get responses from gpt-3.5-turbo model or gpt-4. This video is the first in a series where we'll build an interactive chatbot using Shiny and R.

Wonderful video! Any chance you have another video on the use of R with ChatGPT and embeddings, and then possibly another on R and creating Retrieval Augmented Generation (RAG)? Thanks a ton!
