Codex Now on Your Phone for Remote Work

OpenAI’s Codex is now available in the ChatGPT mobile app, letting you stay connected to your coding agent from anywhere. With over 4 million weekly users, this update brings a fully-featured mobile experience for managing long-running tasks. You can check in on active threads, review outputs like screenshots and terminal logs, approve commands, switch models, or start new work—all from your phone. The system uses a secure relay layer to keep your machines reachable without exposing them to the public internet, syncing session state and context in real time. This means you can unblock work during a commute, investigate a bug while grabbing coffee, or make key decisions on the go. The core value here is flexibility: you don’t have to be tethered to a desk to guide complex agentic workflows. Why it matters: As AI agents tackle longer, more involved tasks, this mobile integration shifts collaboration from real-time supervision to asynchronous check-ins, making remote agent management truly practical for the first time.
