OpenAI Launches Codex Mobile Preview on iOS and Android
OpenAI's Codex coding agent is now available in preview on iOS and Android across all supported regions. The mobile interface lets developers start new work sessions, review agent outputs, steer execution mid-task, and approve or reject next steps—while the actual Codex session continues running on a laptop, Mac mini, or development server. Windows mobile support is listed as coming soon.
Why It Matters
Enabling remote steering of long-running agent sessions from mobile removes the requirement to be at a workstation. Codex running unattended on a dedicated machine while a developer monitors and redirects from a phone is the first broadly deployed example of the async-agent supervision model.
