Why It Matters

The features boost productivity by turning Codex into a remote automation agent for both local apps and browser workflows, opening opportunities for individual and enterprise automation and hybrid work workflows. They also shift more operational control to AI agents, raising considerations for security, access and governance.

Summary

OpenAI's Codex Windows app received two major updates: Computer Use, which lets the AI control desktop applications and perform tasks by taking over the screen and cursor, and mobile access that pairs the ChatGPT iOS/Android app to monitor or start tasks remotely via QR login. Users can also @mention installed apps, enable Computer Use in settings, and leverage Codex-for-Chrome for multi-tab browser automation. The changes aim to let Codex run workflows in the background while users are away from their desks and allow on-the-go oversight or initiation of tasks from a phone.

Original Description

Codex on Windows can now use your computer to work across desktop apps, while you step away from your desk. You can also now use your mobile phone to control the Codex running on your Windows machine.
See how to enable Computer Use in the Codex app, mention installed apps in a conversation, and connect your Windows device to the ChatGPT mobile app to monitor or start tasks on the go.
