This project utilizes the OpenAI Chat API to generate recipes based on user-inputted ingredients and Twilio's SMS API to send these recipes directly to users' cell phones. The application is built using Java, Spring Boot, and ngrok, allowing for local development and deployment of a serverless application that can handle HTTP requests from Twilio's webhook endpoint. The OpenAI Chat API is used to generate responses based on user prompts, while the Twilio SMS API is used to send these responses as SMS messages to users' cell phones. The project also includes an example using the Completion API and demonstrates how to use different models from OpenAI's list of available models.
