GPT (Generative Pre-trained Transformer) is a type of artificial intelligence model designed to understand and generate human-like text. It is trained on vast amounts of written data, allowing it to recognize language patterns, context, and meaning. GPT can answer questions, write articles, summarize information, and even engage in conversation, making it a powerful tool for a variety of applications. Its ability to produce coherent and contextually relevant text has made it widely used in chatbots, content creation, and other language-based technologies.
