Which company created the ChatGPT service?

OpenAI created the ChatGPT service. OpenAI introduced ChatGPT publicly on November 30, 2022, describing it as a conversational artificial-intelligence system based on its GPT family of language models.

OpenAI was founded in 2015 by a group that included Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, John Schulman, and Wojciech Zaremba. It first operated as a nonprofit research organization and later created a capped-profit subsidiary structure.

ChatGPT is a product and service, not the name of the underlying company. It is also distinct from GPT, the model family used in various OpenAI products and applications. The service can generate text, answer questions, summarize material, and assist with many other language tasks.

OpenAI is not itself a conventional publicly traded company with a standard stock-market market capitalization. It is included here because its valuation and partnership with Microsoft have made it a major force in the technology industry.
