OpenAI Codex arrives on ChatGPT mobile app to let developers manage coding tasks remotely
OpenAI rolled out Codex access through the ChatGPT mobile app for iOS and Android, enabling developers to remotely control coding sessions running on their computers. The move comes as OpenAI intensifies competition with Anthropic's Claude Code, with over four million developers now using Codex weekly. Users can review outputs, approve commands, and manage workflows from their phones while files stay secure on their desktop machines.
