Overview
- OpenAI began previewing the feature Thursday on iOS and Android across all ChatGPT plans, letting users reach active Codex sessions from a phone.
- The app loads the live state of a Mac, devbox, or managed host where Codex runs so users can review outputs, approve commands, switch models, or start new tasks.
- A secure relay syncs session context while files, credentials, and permissions stay on the host machine, which avoids exposing trusted computers to the public internet.
- Mobile control works with macOS hosts today, Windows support is coming soon, and access requires updating both the ChatGPT app and the Codex Mac client.
- OpenAI paired the launch with enterprise features including Remote SSH, scoped access tokens, Hooks, and HIPAA‑eligible support, and coverage casts the push as part of a race with Anthropic’s Claude Code.
