OpenAI
OpenAI is the San Francisco company that makes ChatGPT, the GPT model family and the Codex coding agent. It began in 2015 as a nonprofit research lab and, after an October 2025 recapitalization, is now a public benefit corporation controlled by a nonprofit foundation, a structure that shapes debates about its mission and its investors.
