OpenAI Brings Codex Control to iPhone With ChatGPT App Update

OpenAI is bringing Codex to the iPhone, updating the ChatGPT app to interface directly with coding sessions running on a Mac or remote development environment. The feature lets developers monitor, steer, and approve ongoing coding tasks from anywhere without staying tied to their primary workstation.



The integration connects the app to the live state of a host machine. Files, permissions, and local credentials remain securely on the desktop, while updates such as terminal output, code diffs, test results, and screenshots are streamed back to the phone in real time. The update expands on the background computer-use features OpenAI introduced to the Codex app late last year, which allowed agents to operate independently on macOS.


By extending Codex workflows to mobile, users can review trade-offs, approve terminal executions, or redirect a project remotely. The connection relies on a secure relay layer designed to keep trusted machines accessible across authorized devices without exposing them directly to the public internet.

Alongside the mobile rollout, Remote SSH is now generally available, enabling the macOS desktop app to automatically detect hosts from a user's SSH configuration and run threads directly inside remote environments. OpenAI also expanded its enterprise offerings with programmatic access tokens for CI pipelines, custom hooks for scanning prompts or logging conversations, and HIPAA-compliant support for eligible workspaces using Codex locally.

The mobile preview is currently rolling out to the ChatGPT app on iOS and Android across all subscription tiers, including Free and the recently launched ChatGPT Go plan. Access requires updating both the mobile app and desktop client. Support for connecting to the Codex app on Windows is coming soon.
