OpenAI has announced a new way to interact with its codecs system from your smartphone. An update to ChatGPT for iOS is bringing remote access to codecs for iPhone and Mac.
On mobile the codec lives inside the ChatGPT app
While Codex is a standalone app on Mac, OpenAI is putting remote access features inside the ChatGPT app for iPhone.
“Codex is now in the ChatGPT mobile app, so you can stay in the loop from anywhere while Codex works on your laptop, devbox, or in a remote environment,” OpenAI announced today.
The OpenAI codec points to the use of approving tasks and initiating new signals to the system from your phone while you’re away from your computer.
As agents take on longer-term work, a new rhythm of collaboration is emerging. To keep the work moving, you need to be able to easily answer a question, review what the codex found, change direction, accept what comes next, or add a new idea.
“Codex in the ChatGPIT mobile app is a full-featured mobile experience for working with Codex,” the company says.
“When you connect to any of your machines where Codex is running (be it your laptop, a dedicated Mac mini, or a managed remote environment), the app loads the live state from that environment so you can easily work with active threads, approvals, plugins, and project context.”
The setup process looks like this on the Mac app:

OpenAI says ChatGPT’s new codecs features offer much more than remote control
OpenAI describes its codecs tool inside ChatGPIT’s mobile app as much more than a basic remote control.
This is much more than the ability to remotely control a single task or send new tasks to your computer. From your phone, you can work on all your threads, review output, approve commands, change models, or start something new. Your files, credentials, permissions, and local setup remain on the machine where the codecs are working, while updates including screenshots, terminal output, diffs, test results, and approvals flow back to your phone in real time.
Codex remote access via the ChatGPT mobile app begins today for both iPhone and Android.
OpenAI says support for remotely controlling codecs for Windows will continue.

Last month, Codex on Mac gained the ability to use apps on your computer without taking over the cursor. This means that you can use codecs to run tasks on your Mac without giving up the ability to use your machine at the same time.
In addition to enhancing the Codex desktop app, OpenAI recently introduced a subscription designed for Codex users. OpenAI also released GPT-5.5, enhancing the capabilities of ChatGPT and codecs along with Images 2 for image generation.
Codex just came to Mac in February after starting out as a command line interface tool.
