OpenAI brings Codex control to ChatGPT for iPhone and Android

OpenAI has announced a new way to interact with its Codex system from your iPhone. An update to ChatGPT for iOS brings remote access to Codex for Mac to the iPhone.

Codex for mobile lives in the ChatGPT app

While Codex is a standalone app on Mac, OpenAI integrates remote access features into 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 laptops, devboxes, or remote environments.

As agents take on longer duration work, a new rhythm of collaboration emerges. To continue your work, you must be able to easily answer a question, look at what the Codex has found, change direction, approve what’s next, or add a new idea.

Here are more details from today’s OpenAI announcement:

Codex in ChatGPT mobile app is a complete mobile experience for working with Codex. When you connect to one of your machines running Codex (whether it’s your laptop, a dedicated Mac mini, or a managed remote environment), the application loads live state from that environment so you can work seamlessly on active threads, approvals, plugins, and project context.

It’s much more than the ability to remotely control a single task or distribute new tasks to your computer.

Codex remote access via the ChatGPT mobile app is rolling out starting today for iPhone and Android. You can learn more about the new update here.

Last month, Codex on Mac gained the ability to use applications on your computer without taking control of the cursor. This means you can use Codex to run tasks on your Mac without giving up the ability to use your machine at the same time.

In addition to improving the Codex desktop application, OpenAI recently introduced a subscription designed for Codex users. OpenAI also released GPT-5.5, upgrading the capabilities of ChatGPT and Codex, alongside Images 2 for image generation.

Codex only came to the Mac in February after starting out as a command-line interface tool.
