ChatGPT, developed by OpenAI, is an AI-powered chatbot that uses natural language processing to generate human-like responses in conversations, with capabilities in tasks such as translation and summarization. It employs reinforcement learning from human feedback to enhance its interactions, though it has limitations in the accuracy of its outputs and can produce false information depending on the quality of input. Since its launch, ChatGPT has gained significant popularity, drawing over a million users within five days and suggesting a potential shift in how humans interact with technology.
