OpenAI's Codex Mobile Access Now Live in ChatGPT Apps

OpenAI has expanded remote access for its AI assistant Codex, now integrating its capabilities directly into the ChatGPT mobile application for iPhone, iPad, and Android users. This move allows users to manage and interact with Codex from their smartphones, bringing enhanced productivity for developers and users working with AI-driven tasks on the go.

Codex, previously a standalone application on Mac, now offers its remote access features within the familiar interface of the ChatGPT mobile app. "Codex is now in the ChatGPT mobile app so you can stay in the loop from anywhere while Codex gets work done across your laptops, devboxes, or remote environments," OpenAI announced. The company highlights uses such as approving Codex tasks and initiating new prompts for the system remotely, facilitating continuous workflow even when away from a primary workstation.

This new integration signifies a shift towards more fluid collaboration with AI agents, especially as they handle increasingly complex, longer-running tasks. The ability to quickly review Codex outputs, adjust strategies, approve next steps, or introduce new ideas directly from a mobile device streamlines the development and AI management process. "Codex in the ChatGPT mobile app is a fully-featured mobile experience for getting work done with Codex," stated the company. "When you connect to any of your machines where Codex is running (whether that’s your laptop, a dedicated Mac mini, or a managed remote environment), the app loads the live state from that environment so you can work fluidly across active threads, approvals, plugins, and project context."

Seamless Mobile Integration and Enhanced Control

The setup process for this mobile integration is designed to be straightforward. After initial setup on the Mac application, a QR code is presented. Users can then scan this code using the ChatGPT app on their iPhone, iPad, or Android device to establish the connection. OpenAI emphasizes that these new Codex features within the ChatGPT mobile app extend beyond simple remote control, offering a comprehensive mobile experience for managing Codex operations.

Users can now interact with all active threads, review outputs, approve commands, switch between different AI models, or initiate new projects directly from their phones. Crucially, sensitive data such as files, credentials, and permissions remain securely on the machine where Codex is operating. Updates, including screenshots, terminal output, code differences (diffs), test results, and approval statuses, are transmitted back to the mobile device in real-time. This ensures that users have the most up-to-date information without compromising the security of their primary computing environments. This real-time synchronization is a key component of the collaboration experience.

The remote access feature through the ChatGPT mobile app is available immediately. To utilize it, users need the latest versions of Codex for Mac and the ChatGPT app for iOS and Android. OpenAI has also indicated that support for remotely controlling Codex on Windows machines will be provided in a future update. This expansion into mobile accessibility for powerful AI tools like Codex is part of a broader trend towards making advanced AI more accessible and integrated into daily workflows. OpenAI recently enhanced the Codex desktop app with the ability to use on-device applications without direct cursor control, and also introduced a subscription tier specifically for Codex users. Furthermore, the company recently unveiled GPT-5.5, an upgrade enhancing ChatGPT and Codex capabilities, alongside Images 2 for improved AI image generation.
