OpenAI Codex mobile integration expands coding workflows

OpenAI has integrated its Codex coding tool into the ChatGPT mobile app, enabling users to monitor and manage development workflows remotely on iOS and Android devices. This new functionality allows users to view live Codex environments and interact with their projects from their phones, including reviewing outputs, approving commands, and switching models. The update follows recent enhancements like background execution on desktops and a Chrome extension, intensifying competition with rivals like Anthropic, which offers similar remote monitoring features for its Claude Code tool. This move signifies a push towards more accessible and integrated AI development experiences.
