OpenAI has launched a preview of Codex inside the ChatGPT mobile app, allowing users to monitor and interact with work running on their development machines from a phone. The company says the mobile experience loads the live state from connected environments so users can review outputs, approve commands, change models, or start new threads while files and credentials remain on the host machine.
Mobile access to active threads and approvals
According to OpenAI, the app synchronizes session state and context through a secure relay layer that keeps trusted machines reachable across devices without exposing them directly to the public internet. Updates such as screenshots, terminal output, diffs and test results flow back to the mobile app in real time, the company says.
OpenAI noted that more than 4 million people now use Codex every week and described common mobile use cases: starting an investigation while away from a desk, choosing between approaches during a commute, preparing briefings for customer calls, or sending a fresh idea to Codex so work can begin before returning to a computer. The company frames these as ways to unblock or steer longer-running agent work.
Enterprise features and availability
OpenAI said Remote SSH is generally available, with the desktop app automatically detecting hosts from an SSH configuration so projects and threads can run inside remote machines as if local. That connectivity can then be accessed across authorized ChatGPT devices through the same relay infrastructure.
The company also announced additional features: Programmatic access tokens for scoped credentials (available on Enterprise and Business plans), and Hooks, now generally available, to scan prompts, run validators, log conversations or customize Codex behavior. OpenAI added support for HIPAA-compliant use of Codex in local environments (CLI, IDE, App) for eligible ChatGPT Enterprise workspaces.
OpenAI said Codex in the ChatGPT mobile app is rolling out in preview on iOS and Android across all plans, including Free and Go, in all supported regions. Users should update the ChatGPT mobile app and the Codex macOS app to try it; phone support for connecting to the Codex app on Windows is coming soon. Remote SSH and Hooks are available on all plans, while programmatic access tokens are limited to Enterprise and Business plans. HIPAA-compliant use applies only to eligible ChatGPT Enterprise workspaces when Codex is used in local environments.
