OpenAI has introduced Codex support in the ChatGPT mobile app, allowing users to monitor and manage coding tasks running across laptops, remote machines, and managed environments directly from their phones.
The feature, currently rolling out in preview on iOS and Android, is available across all ChatGPT plans, including Free and Go. The support for connecting phones to the Windows Codex app is expected later.
OpenAI said more than four million people now use Codex every week.
“Now you can do that from your phone,” the company said in its announcement, referring to actions such as answering questions, approving commands, reviewing outputs, or changing directions while Codex handles long-running work.
According to OpenAI, the mobile experience mirrors the live state of whichever machine Codex is connected to, including laptops, Mac minis, or remote development environments.
Users can access active threads, approvals, plugins, project context, screenshots, terminal output, test results, and code diffs in real time while files and credentials remain on the connected machine.
“This is more than the ability to remotely control a single task or dispatch new tasks to your computer,” OpenAI said. “From your phone, you can work across all of your threads, review outputs, approve commands, change models, or start something new.”
The company said Codex relies on a secure relay layer that keeps trusted machines reachable without exposing them directly to the public internet. The infrastructure also synchronises session state and context across devices that are signed in to ChatGPT.
OpenAI outlined several use cases for the mobile integration, including investigating bugs, reviewing refactoring decisions during commutes, preparing summaries for customer calls, and initiating new coding tasks while away from a desk.
In one example, the company said users can ask Codex to inspect files, reproduce browser issues, run tests, and work toward fixes while they are away from their computer.
The company also announced that Remote SSH support is now generally available, enabling Codex to connect directly to managed remote environments. The desktop app can detect SSH hosts from a user’s configuration and allow projects and threads to run inside remote machines.
OpenAI said the same relay infrastructure makes those remote environments accessible across authorised ChatGPT devices, enabling users to begin work on desktop systems and continue supervising tasks from mobile devices.
The company additionally introduced programmatic access tokens for enterprise and business users. OpenAI said these scoped credentials can be used for CI pipelines, release workflows, and internal automations.
Hooks, now generally available across all plans, can be configured to scan prompts for secrets, run validators, log conversations, create memories, or customise Codex behaviour for specific repositories and directories.
OpenAI also announced support for HIPAA-compliant use of Codex in local environments for eligible ChatGPT Enterprise workspaces. The company said the capability is intended to help healthcare organisations support patient care and operational workflows.
