OpenAI Launches Codex Mobile Preview to Control Autonomous Agents on the Go

OpenAI launched a preview of Codex within the ChatGPT mobile app for real-time interaction with active agent sessions. While the agent executes on a local machine or remote devbox, you can review terminal outputs, approve next steps, and start new threads from your phone. A secure relay layer handles state synchronization.

iOS and Android (Preview)
Supported plans
Free, Go, Enterprise, and others
New GA features
Remote SSH and Hooks
Enterprise features
Programmatic access tokens and HIPAA compliance
Sync mechanism
Secure relay layer

This update addresses the "Human-in-the-Loop" (HITL) bottleneck where agents pause for human approval before proceeding. By turning the mobile app into a remote steering wheel, OpenAI mirrors the Claude Code Remote Control capability. It ensures that long-running tasks, like Daybreak's autonomous cyber defense patches, remain unblocked.

You can now unblock refactors or bug fixes during a commute by reviewing diffs and test results in the app. The release also moves Remote SSH and Hooks to general availability. Codex on mobile is rolling out to all users, including Free and Go tiers, on iOS and Android.

Still wondering? A few quick answers below.

Codex in the ChatGPT mobile app is a preview feature that allows users to monitor and steer autonomous coding tasks from their phones. It acts as a remote interface for Codex sessions running on a separate computer, such as a laptop or devbox, enabling users to review outputs and approve next steps while away from their desks.

The mobile app connects to a user's machine where Codex is physically running through a secure relay layer. This infrastructure synchronizes the live state of the environment, including terminal output, screenshots, and code diffs, across devices. This allows the agent to continue using local files and credentials while the user provides guidance from the mobile interface.

The Codex mobile preview is rolling out to all ChatGPT users on iOS and Android, including those on the Free and Go plans. To use it, users must update both their ChatGPT mobile app and the Codex desktop application. The feature is available in all regions currently supported by OpenAI's mobile services.

While the Codex mobile app is currently available for iOS and Android, support for connecting the mobile app to the Codex application on Windows is listed as coming soon. Currently, the mobile preview primarily supports connections to Codex running on macOS or remote environments accessible via the newly released Remote SSH feature.

Hooks are a generally available feature used to customize Codex behavior by scanning prompts for secrets or running custom validators. Programmatic access tokens are scoped credentials available for Enterprise and Business plans, designed to integrate Codex into automated workflows like CI pipelines. These tools help teams manage and secure agentic coding at an enterprise scale.
