Pachocki, part of Business Insider's 2024 AI Power List, joined OpenAI in 2017 after completing a doctorate in computer science at Carnegie Mellon University. He was promoted to the company's chief scientist in May following the departure of its cofounder Ilya Sutskever. Pachocki had already been working closely with Sutskever on some of OpenAI's most ambitious projects including an advanced-reasoning model known as Q* and later renamed Strawberry. Even before officially taking on the mantle of chief scientist, Pachocki had already emerged as a guiding force behind OpenAI's research efforts. Sam Altman has called Pachocki "easily one of the greatest minds of our generation."
