OpenAI’s Codex is now in the ChatGPT mobile app

OpenAI has introduced a new feature that allows users to access its Codex AI tool within the ChatGPT mobile app, enabling remote control of desktop tasks directly from smartphones. This development expands the accessibility of Codex, which can write code and operate applications on computers, to mobile devices, making it easier for users to manage their workflows on the go.

According to a blog post from OpenAI, the new feature enables users to connect their mobile devices to a desktop running Codex, allowing them to review outputs, approve commands, change models, or initiate new tasks. The system maintains security by keeping files, credentials, permissions, and local setups on the desktop machine, while real-time updates such as screenshots, terminal outputs, and test results are transmitted back to the phone. The rollout is currently in preview and available to all ChatGPT plans, including free and paid tiers, on both iOS and Android platforms.

Why It Matters

This integration marks a notable advancement in making AI-powered coding and desktop automation more accessible via mobile devices. It enhances user flexibility and productivity by enabling remote management of complex tasks without needing direct desktop access. As AI tools like Codex become more integrated into daily workflows, this development could accelerate the adoption of AI-assisted programming and automation, especially among developers and enterprise users.

Background

OpenAI has been actively developing and expanding Codex’s capabilities, including recent updates to operate applications on macOS. The company’s push to integrate Codex into mobile platforms follows rising competition from other AI coding assistants like Anthropic’s Claude Code. This move is part of OpenAI’s broader strategy to create a ‘superapp’ ecosystem that consolidates AI functionalities across devices and platforms. The rollout of this feature coincides with increased interest in AI-driven automation tools across industries.

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

What Remains Unclear

It is not yet clear how widely adopted the feature will become or how it will perform in different real-world scenarios. Details about user privacy, security measures, and potential limitations of remote control are still emerging, and the full scope of functionality is yet to be seen as the rollout continues.

What’s Next

OpenAI is expected to monitor user feedback during the preview phase and may introduce further enhancements or expand compatibility. Future updates could include broader device support, additional security features, or deeper integration with other AI tools within the ChatGPT ecosystem.
