ChatGPT refers to a type of conversational artificial intelligence (AI) system that is powered by the GPT (Generative Pretrained Transformer) language model developed by OpenAI. The GPT language model has been trained on vast amounts of text data, allowing it to generate human-like responses to natural language questions and prompts. When integrated into a chat interface, the resulting system is often referred to as a ChatGPT. The goal of ChatGPT is to provide a natural and human-like interaction with users, allowing them to ask questions, receive answers, and engage in conversation, as they would with another person. The technology behind ChatGPT is constantly evolving, with researchers and developers working to improve its accuracy and capabilities.
