ChatGPT is an artificial intelligence (AI) chatbot developed by OpenAI and released in November 2022.
Although the core function of a chatbot is to mimic a human conversationalist, ChatGPT is versatile. It can write and debug computer programs, mimic the style of celebrity CEOs and write business pitches, compose music, teleplays, fairy tales and student essays, answer test questions (sometimes, depending on the test, at a level above the average human test-taker), write poetry and song lyrics, translate and summarize text, emulate a Linux system; simulate entire chat rooms, play games like tic-tac-toe and simulate an ATM. ChatGPT's training data includes man pages, information about internet phenomena such as bulletin board systems, and multiple programming languages.
ChatGPT has limited knowledge of events that occurred after September 2021.
