Belgian engineer who runs OpenAI's core products — ChatGPT, ChatGPT Work, Codex and, since September 2026, the Dots personal-agent platform, with a remit that also reaches the API, agent infrastructure and enterprise. Spent years at Google on Google Maps and then at Google DeepMind on research infrastructure and human-data systems for frontier models, before joining OpenAI in 2024 as an engineering lead for Codex. Oversaw the 2025 launch of the Codex coding agent and its growth into a mass product; argues that most internet actions will soon be taken by persistent agents rather than hand-built loops and graphs, and that human taste matters more as typing speed matters less.
