who created chatgpt

ChatGPT was created by OpenAI, an AI research company founded in 2015 by Elon Musk, Sam Altman, and a team of scientists and engineers. The development of ChatGPT was not the work of a single person but a collaborative effort involving many researchers, engineers, and ethicists over several years. The chatbot builds on earlier models like GPT-1, GPT-2, and GPT-3, with the latest versions running on more advanced systems such as GPT-4 and GPT-5. OpenAI's mission has been to develop artificial intelligence that benefits everyone, and ChatGPT has evolved through constant refinement and improvements by the OpenAI team.
