Getting Started

ChatGPT is a web-based chatbot application that uses OpenAI's GPT-3 language model to generate natural language responses to user inputs. The application was developed using React, Express, and Node.js, and the OpenAI API was accessed using the @openai/ai-engine package.

The application features a clean and modern user interface, and allows users to chat with the chatbot in real time. The GPT-3 model used in the application is the text-davinci-003 model, which is one of the most advanced language models currently available, and is capable of generating human-like responses to a wide variety of prompts.

ChatGPT is designed to be easily deployable, and can be run on any system that supports Node.js and the OpenAI API. It can also be customized to fit specific use cases and domains, making it a powerful tool for developers and businesses looking to incorporate natural language processing into their applications.
