Greg Brockman

Greg Brockman is an American software engineer and the co-founder and president of OpenAI. Before entering AI, he worked at Stripe, where he became chief technology officer. He attended Harvard and the Massachusetts Institute of Technology without completing a university degree, and developed his career through hands-on engineering.

Brockman joined OpenAI’s founding effort in 2015 and initially served as its chief technology officer. His work has combined organizational leadership with technical involvement in machine learning and the infrastructure required to train and deploy models. In his own writing, he describes the transition from general software engineering to becoming a machine-learning practitioner.

He has also explained OpenAI’s systems publicly, including through demonstrations of GPT-4 and tools connected to ChatGPT. These products resulted from large research and engineering teams, rather than the work of one founder. Brockman’s relevance to AI lies in helping assemble and operate the institution that developed them, while connecting research ambitions with practical systems and applications.
