ChatGPT Codex brings Computer Use to Windows, plus remote control from iOS/Android
OpenAI on May 29 expanded ChatGPT's Codex app with Computer Use on Windows — enabling eligible users to have ChatGPT directly drive Windows applications for software testing, debugging, and iterative refinement. The release pairs with a remote-control feature: from ChatGPT on iOS or Android, or from Codex on Mac, a user can start, review, and steer tasks running on their Windows machine, with work continuing in the background.
OpenAI announced via its official X account: 'Windows users, this one's for you. Computer use now works on Windows, so Codex can take action on your Windows computer.' The post highlighted the mobile-to-Windows remote-control flow as the key unlock for developers who want to dispatch agents during commute or off-desk time. Beyond the headline feature, OpenAI shipped infrastructure improvements for responsiveness and in-app browser performance, plus Codex Profiles — a new dashboard for tracking user activity and token consumption per profile, useful for teams.
Competitive context: Computer Use on Windows directly answers Anthropic's existing Claude Computer Use feature (which has been more Mac-friendly) and Microsoft's own Copilot Windows integrations. The timing is pointed — Microsoft's Build keynote opens June 2 with its in-house coding model launch, and OpenAI shipping deeper Windows integration the week before is a clear marker that the OpenAI-Microsoft partnership thaw cuts both ways. Bloomberg also reported this week that OpenAI is weighing legal action against Apple over the stalled ChatGPT-Siri integration, with the Apple front going cold while the Windows front heats up.
Greg Brockman concurrently asked users via X to report ChatGPT bugs, signaling the Codex team and 'codex itself' are pushing rapid iteration. Watch next: which Computer Use workflows actually stick with developers (testing/debugging is a narrower beachhead than general automation), and whether OpenAI exposes Computer Use as an API for third-party agent builders.
