Codex Adds Windows Computer Use + ChatGPT Mobile Windows Connections for On-the-Go Steering

By 1 min read

OpenAI says Codex can now use Computer use on Windows to test apps, debug flows, and review work on your Windows machine, and that Codex in the ChatGPT mobile app can connect to Windows machines so you can steer tasks from your phone.

OpenAI Developers says Codex now supports more of the Windows developer loop.

According to the post, "With Computer use on Windows, Codex can test apps, debug flows, and review work where your project context lives." (OpenAI Developers)

OpenAI Developers also says Codex in the ChatGPT mobile app "lets you connect to Windows machines and keep steering from your phone." (OpenAI Developers)

Why It Matters

If you do most of your development on Windows, this is a practical workflow upgrade: Codex can take action directly inside the environment where your app and tooling run, and you can review/steer long-running tasks from mobile without staying at your desk.

What We Can (and Can't) Verify Today

OpenAI Developers did not include a durable documentation link in the announcement itself, so the quotes above are from the post. Since then, OpenAI's documentation has caught up and now carries both claims (verified 2026-08-06):

  • The Computer Use doc states that "In supported regions, Computer Use in the ChatGPT desktop app is available on macOS and Windows with ChatGPT Work and Codex." One difference from macOS worth knowing: on Windows, Computer Use runs on the active desktop and cannot operate in the background while you keep using the same session.
  • The remote-connections doc documents controlling Codex on a macOS or Windows host from the ChatGPT mobile app, which is the "keep steering from your phone" claim. Our Codex in ChatGPT mobile writeup covers the setup flow.
