Wojciech Zaremba is a Polish-American AI researcher and co-founder of OpenAI, the company behind ChatGPT and GPT-4. A former International Mathematical Olympiad silver medalist from Kluczbork, Poland, he holds dual master's degrees from the University of Warsaw and École Polytechnique, and a PhD from NYU under Yann LeCun. At OpenAI he has led robotics (including the Dactyl hand that solved a Rubik's Cube one-handed), the Codex project powering GitHub Copilot, and the RLHF human feedback infrastructure that shaped ChatGPT's alignment. One of the few original co-founders still at the company after a decade, he is regarded as one of the most technically consequential and quietly influential figures in modern AI.
Hamel Husain is a machine learning engineer with 25+ years of experience who built part of the foundation beneath GitHub Copilot - his CodeSearchNet project was early LLM research later used by OpenAI for code understanding. Today he runs Parlance Labs, consults with AI teams across 35+ products, co-authored O'Reilly's 'Evals for AI Engineers', and teaches thousands of engineers how to move beyond vibes and actually measure their AI systems.
