After graduation, Pachocki did postdoctoral work at Harvard University and the Simons Institute for the Theory of Computing.[4]

OpenAI

In 2017, Pachocki joined OpenAI.[1][7] In 2021, he became OpenAI's research director where he led the development of GPT-4 and OpenAI Five. In May 2024, he became chief scientist after his mentor Ilya Sutskever left the company.[4] OpenAI CEO Sam Altman has called Pachocki "easily one of the greatest minds of our generation".[1]

In September 2026, Pachocki published an essay entitled An Alien Mind in which he discusses the rapid advancement of AI systems and the ongoing challenge of ensuring they remain aligned with human goals. He also called for the establishment of shared safety regulations and an international cooperation regarding the development of the AI technology.[8]
