What is ChatGPT and how does it work?

ChatGPT is an AI-powered chatbot developed by OpenAI that uses advanced natural language processing (NLP) to generate human-like responses. It is based on the GPT (Generative Pre-trained Transformer) architecture, which is trained on vast amounts of text data to understand and generate meaningful conversations. ChatGPT works by analyzing user input, predicting the most relevant responses, and providing coherent and context-aware replies.
