OpenAI posted on X that Codex is now in preview inside the ChatGPT mobile app, letting users “start new work, review outputs, steer execution, and approve next steps” from iOS or Android while Codex continues running on a laptop, Mac mini, or devbox.
A second post from the company states that the preview is rolling out today in all supported regions on iOS and Android, with support for connecting a phone to the Codex app on Windows “coming soon.”
Some replies pointed to rough edges. One user mentioned a QR-code pairing flow that appeared to stall on “waiting for desktop,” while another reported a connection error after denying access on a MacBook and trying again on an iPhone. A separate commenter described the update as useful but “really buggy rn,” according to the reply thread.
