Pachocki left an academic career in theoretical computer science to join OpenAI in 2017 and replaced Sutskever as chief scientist in 2024. Along with Sutskever, he is one of the key architects of OpenAI's so-called reasoning models—especially o1 and o3—which are designed to tackle complex tasks in science, math, and coding.
