Codex is now in 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.

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.

Stay connected to active work from anywhere

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.

Step in when it matters

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:

Start investigating a bug while waiting for your coffee. Because Codex is running from your development environment, it can begin inspecting the relevant files, reproduce the issue in the browser, run tests, and begin working toward a fix. If Codex needs clarification or permission to continue, you can answer or approve from your phone. And as it works, you can follow along with screenshots, terminal output, test results, and eventually review the resulting diff before you are back at your computer.
Reach a decision point during your commute. Before leaving for the office, you ask Codex to take on a refactor that will need time to work through, expecting to review the result when you get to your desk. Mid-commute, Codex finds two viable approaches and needs your direction before it can continue. From your phone, you review the tradeoffs, choose a path, and by the time you arrive, the task has kept moving in the direction you wanted.
Head into a fast-moving customer conversation better prepared. You come out of back-to-back meetings to find a support issue evolving across Slack, email, documents, and browser-based tools, with a customer call coming up next. From your phone, you ask Codex to synthesize the latest updates, flag the key open questions, and prepare a concise briefing for the conversation. If new details come in, you can ask Codex to refresh the summary before you join.
Turn a new idea into forward motion while it is still fresh. Whether you are at lunch, out for a walk, or listening to something that sparks a thought, you can send it to Codex from your phone by starting a new thread or adding it to active work. The task can begin taking shape before you return to your desk, without pulling you fully out of the moment that sparked it.

Run Codex in enterprise environments

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:

Programmatic access tokens provide scoped credentials that can be issued directly from ChatGPT workspace settings for CI pipelines, release workflows, and internal automations.
Hooks⁠(opens in a new window) are now generally available and can be used to scan prompts for secrets, run validators, log conversations, create memories, or customize Codex behavior for specific repositories and directories.
Support for HIPAA-compliant use of Codex in local environments (CLI, IDE, App) for ChatGPT Enterprise workspaces, enabling healthcare organizations to support patient care and operational workflows with greater speed and confidence.

Availability

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.
