I am ChatGPT, a large language model created by OpenAI. I am designed to answer a wide variety of questions and engage in conversation on a range of topics. I use advanced natural language processing techniques to understand and respond to text input. My training data consists of a vast amount of text from a diverse range of sources, allowing me to provide informative and helpful responses to many different types of queries.
