OpenAI’s Codex is now in the ChatGPT mobile app

OpenAI has integrated its Codex AI coding tool into the ChatGPT mobile app, enabling users to control and monitor coding tasks on their desktop computers directly from their phones. The feature is available now as a preview for all ChatGPT plans, including free and paid options.

OpenAI announced that users can now access Codex within the ChatGPT mobile app, allowing them to send commands, review outputs, and approve actions on their desktop machines remotely. This integration enables real-time updates, including screenshots, terminal outputs, diffs, and test results, which flow back to the user’s phone. The feature is compatible with both iOS and Android platforms and is currently in a preview phase.

According to a blog post from OpenAI, the system ensures that files, credentials, permissions, and local setups remain on the machine where Codex operates, maintaining security and control. Users can work across multiple threads, review outputs, and initiate new tasks remotely, streamlining workflows for developers and power users.

Why It Matters

This development signifies a step forward in making AI-powered coding tools more accessible and integrated into daily workflows. By enabling remote management of coding tasks, OpenAI enhances productivity for developers, especially those working across multiple devices or remotely. The expansion of Codex into mobile apps also positions OpenAI to better compete with other AI coding assistants and to grow its enterprise and individual user base.

Background

OpenAI’s Codex, launched in 2021, is known for its ability to generate code and control applications based on natural language prompts. The company has been expanding its capabilities, notably with recent updates allowing Codex to operate on macOS and serve as part of a broader desktop “superapp.” The move to integrate Codex into the mobile app follows a surge in interest in AI coding assistants, notably Anthropic’s Claude Code, prompting OpenAI to accelerate its development and deployment efforts.

“With your phone, you can ‘work across all of your threads, review outputs, approve commands, change models, or start something new’ in Codex.”

What Remains Unclear

It is not yet clear how widely the feature will be adopted once the preview phase concludes or whether additional functionalities will be added before a full rollout. Details about specific security measures or limitations during the preview are still emerging.

What’s Next

OpenAI is expected to monitor user feedback during the preview phase and may introduce further updates or expand the feature’s capabilities. A full rollout to all users, including enterprise clients, could follow depending on the initial response and technical stability.
