Summary
The frontier AI labs have spent years promising that effective AI agents will act as their minions in the workplace and at home, and that might soon be a reality. Use of Codex, OpenAI's agentic coding and work platform, is accelerating, according to a new report from OpenAI, Columbia, Duke and the University of Pennsylvania. The researchers separate Codex users into three categories: OpenAI employees, outside organizations and individual users. 99.8% of OpenAI employees' output tokens were produced with Codex, compared with 63% for organizations and 16.5% for individuals. OpenAI's own Codex use is meant to represent how users might turn to agents when cost, access, training and buy-in are mostly removed.
