OpenAI brings Codex to phones via ChatGPT app

ChatGPT-maker OpenAI introduced Codex desktop application in February this year. The company has now announced that its AI coding assistant, Codex is now available on mobile via the ChatGPT app. This will enable the developers to manage and approve coding tasks directly from their phones. The rollout, currently in preview for iOS and Android, expands Codex’s reach beyond desktops and remote environments. “Codex is now in the ChatGPT mobile app so you can stay in the loop from anywhere. More than 4 million people now use Codex every week, and we’re seeing how much those small moments matter. A quick check-in can keep a thread moving, prevent unnecessary rework, or help Codex make progress with the right context. Now you can do that from your phone,” said OpenAI.

Codex while on the go

With the access of Codex on mobile, the developers can now connect to laptops, devboxes, or managed remote environments and new live states from those machines. Updates such as screenshots, terminal output, diffs, and test results are streamed to mobile devices, enabling quick approvals or corrections even when away from a workstation. Under the hood, Codex uses a secure relay layer that keeps trusted machines reachable across devices without exposing them directly to the public internet. That relay also keeps active session state and context synced anywhere you’re signed in with ChatGPT.
