Inside OpenAI: The Duo Driving Breakthrough AI Research and Innovation
Explore the roles of Mark Chen and Jakub Pachocki in driving OpenAI's advanced research and the development of AI models like GPT-5, highlighting recent achievements and challenges in the race for AGI.
The Faces Behind OpenAI's Cutting-Edge Research
OpenAI has often been associated with its charismatic CEO, Sam Altman, but the real engine behind its groundbreaking technology lies with its co-heads of research, Mark Chen and Jakub Pachocki. These two leaders are responsible for steering OpenAI’s research to stay ahead of formidable competitors like Google.
Roles and Backgrounds
Mark Chen, who joined OpenAI in 2018, previously worked as a quantitative trader and led key projects such as DALL-E, image recognition integration into GPT-4, and Codex, the coding AI behind GitHub Copilot. Jakub Pachocki, former academic in theoretical computer science and chief scientist since 2024, focuses on reasoning models designed for complex scientific, mathematical, and coding tasks.
Recent Achievements in AI Competitions
OpenAI’s models recently excelled in highly competitive arenas: finishing second in the AtCoder World Tour Finals, a prestigious programming contest, and securing gold-medal-level scores in the 2025 International Math Olympiad. These feats highlight the AI’s advanced problem-solving and creative capabilities, particularly in programming and math, which the duo considers foundational to achieving more general intelligence.
Balancing Research and Product Development
While OpenAI maintains its identity as a research lab, it operates in a fiercely competitive market, necessitating rapid product deployment. Chen and Pachocki emphasize the importance of experimental models released to the public as part of ongoing research and societal education. They acknowledge the tension between long-term research and immediate product needs but see it as a delicate balance crucial to progress.
The Vision for AGI and Scientific Advancement
The duo is focused on overcoming current AI limitations, particularly in reasoning — breaking down complex problems into manageable steps and extending autonomous model operation over longer periods. They envision AI not only assisting but autonomously conducting scientific research, potentially accelerating technological progress significantly.
Addressing Safety and Alignment
OpenAI’s former superalignment team, dedicated to ensuring AI safety against hypothetical superintelligence risks, has disbanded amid staff departures citing insufficient support. However, Chen and Pachocki stress that alignment is now integrated into OpenAI’s core operations, focusing on practical alignment challenges with current models rather than theoretical future risks.
The Path Forward
Despite challenges and internal tensions, Chen and Pachocki remain confident in AI’s trajectory, supported by scaling laws and continuous research breakthroughs. With major product launches like GPT-5 on the horizon, their combined vision and leadership continue to shape the future of AI technology.
