Why Codex is at the heart of OpenAIs plans to sell AI agents to enterprises | Fortune
Summary
OpenAI reports breakout growth for Codex (GPT-5.3), with over 1 million desktop app downloads, about 1.6 million weekly active users, and token usage up fivefold. Companies including Cisco, Nvidia, Ramp, Rakuten, and Harvey have deployed Codex across developer teams, and OpenAI plans to expand the Codex agent harness beyond coding to enable non-technical enterprise users. The company is building composable Skills and marketplaces while working on security, managed deployments, and on-premises options to sandbox agent capabilities. That product momentum has been largely eclipsed by controversy over OpenAI's deal with the Pentagon and increased competition from Anthropic, which has seen strong enterprise adoption.
