Create an AI Commentator with GPT-4V, OpenAI TTS, Replit, LangChain, and SendGrid

This application uses OpenAI's new Vision API (GPT-4V), Twilio SendGrid, Replit, LangChain, and Streamlit to generate commentary in the style of Stephen Smith for an input basketball video file. The app allows users to upload a video file, enter their email address, and click a button to create a new video with audio commentary in the style of Stephen Smith. The generated audio is then merged with the original video and displayed on the web page. The output video can be emailed as an attachment using Twilio SendGrid. The application uses various libraries and APIs, including OpenCV, LangChain CSV Agents, and OpenAI's Chat Completion model.
