Work with Codex from anywhere

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.

As agents take on longer-running work, a new rhythm for collaboration is emerging. To keep work moving, you need to be able to easily answer a question, review what Codex found, change direction, approve what comes next, or add a new idea.

More than 4 million people now use Codex every week, and we’re seeing how much those small moments matter. A quick check-in can keep a thread moving, prevent unnecessary rework, or help Codex make progress with the right context. Now you can do that from your phone.

Codex in the ChatGPT mobile app is a fully-featured mobile experience for getting work done with Codex. 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.

This is more than the ability to remotely control a single task or dispatch new tasks to your computer. From your phone, you can work across all of your threads, review outputs, approve commands, change models, or start something new. Your files, credentials, permissions, and local setup stay on the machine where Codex is operating, while updates flow back to your phone in real time, including screenshots, terminal output, diffs, test results, and approvals.

Under the hood, Codex uses a secure relay layer that keeps trusted machines reachable across devices without exposing them directly to the public internet. That relay also keeps active session state and context synced anywhere you’re signed in with ChatGPT.

As Codex handles work over longer stretches, timely guidance becomes a bigger part of keeping that work useful. From your phone, you can start work when it is top of mind, unblock it when your judgment is needed, and stay close to the result as it takes shape.

With Codex in your pocket, now you can:

Many teams already develop inside managed remote environments that provide approved dependencies, credentials, security policies, and compute resources.

With Remote SSH now generally available, Codex can connect directly into those environments. The desktop app automatically detects hosts from your SSH configuration and lets you create projects and run threads inside remote machines just like you would locally.

Once connected, those environments can become accessible across your authorized ChatGPT devices through the same secure relay infrastructure. That means you can start work on your desktop, steer execution from your phone, and keep long-running tasks moving without staying tied to a single machine.

We’re also releasing several updates that expand how teams can automate, customize, and manage Codex at scale:

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. Update the ChatGPT mobile app and the Codex app on macOS to try it out. Support for connecting your phone to the Codex app on Windows is coming soon.

Remote SSH and Hooks are available on all plans as well. Programmatic access tokens are available on Enterprise and Business plans. HIPAA-compliant use is supported for eligible ChatGPT Enterprise workspaces only when Codex is used in local environments.
