ChatGPT is an AI-powered chatbot that utilizes natural language processing technology to comprehend human language and provide answers or engage in conversations with users. Built on OpenAI's GPT model, a pre-trained language model that can generate text close to human-level quality, ChatGPT continuously learns and improves its answering and conversational abilities through interactions with users, thus delivering a better user experience. ChatGPT can be utilized in a variety of scenarios, including customer service, education, and entertainment, to improve efficiency and user satisfaction.

Creating an account with ChatGPT is free, however, upgrading to the premium version requires additional payment.
