The feature is currently in preview across iOS and Android in supported regions and requires updated versions of both the ChatGPT mobile app and Codex for macOS. Windows support is planned for later release.
For development teams using Codex, the mobile expansion removes friction from the approval workflow. Developers can now unblock AI-assisted coding tasks from anywhere rather than requiring desktop access to review and authorize agent actions. Teams should evaluate whether this capability affects their current code review processes and governance policies around AI-generated code.
