OpenAI Brings Codex to ChatGPT Mobile — Control Your AI Coding Agent from Your Phone

Codex Goes Mobile: Remote Control for AI Coding

OpenAI brought Codex to the ChatGPT iOS and Android apps on May 14, turning phones into a control surface for Codex sessions already running on a desktop, devbox, or remote environment. The phone doesn't process the codebase — it streams real-time updates from wherever Codex is working.

Real-Time Updates: Diffs, Terminal Output, Test Results

Screenshots, terminal output, code diffs, and test results all flow back to the phone in real time. Users can approve or reject each step, keeping human oversight on AI-driven code changes. Files, credentials, and local permissions stay on the host machine, keeping the security model intact.

All Plans, Including Free

The preview rolls out across all ChatGPT plans, including Free and Go. Over 4 million people now use Codex each week, and mobile access extends the agent's reach beyond desktop sessions. Current support covers macOS-hosted Codex sessions; Windows phone connectivity is coming in a future update.
