Codex in the ChatGPT mobile app
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.
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.
Codex uses a secure relay layer that keeps trusted machines reachable across devices without exposing them directly to the public internet. With Codex in your mobile, 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 synthesise 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.
Codex in Enterprise environments
With Remote SSH now generally available, Codex can connect directly to remote 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.
OpenAI has also released several updates that expand how teams can automate, customise, 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 customise Codex behaviour for specific repositories and directories.
- Support for HIPAA-compliant use of Codex in local environments (CLI, IDE, App) for ChatGPT Enterprise workspaces, enabling healthcare organisations 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. Users are advised to update the ChatGPT mobile app and the Codex app on macOS to try it out. Meanwhile, 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.
