Meet the OpenAI Engineer Leading ChatGPT's Biggest Transformation Yet

Overview

OpenAI has handed Thibault Sottiaux, the engineer who built its Codex coding tool into one of the company's fastest-growing products, responsibility for the biggest redesign of ChatGPT since its launch. Codex passed 5 million weekly active users by early June 2026, about six times its level when the desktop app shipped in February 2026. His mandate centers on personalization, memory across sessions, and smarter defaults so people need less careful prompting.
