OpenAI integrated its Codex AI coding assistant into the ChatGPT mobile app for iOS and Android. This update allows developers to manage coding tasks remotely by connecting to primary development machines from their smartphones.

The feature enables users to monitor long-running tasks, review progress, and approve actions while away from a desktop environment. The mobile app acts as a remote control, streaming terminal activity and code changes in real-time through a secure relay system.

This architecture ensures that sensitive files and credentials remain on the host machine. OpenAI is rolling out the capability in a preview phase to all ChatGPT users, including those on free plans, across all supported regions.
