OpenAI has integrated its coding tool Codex into the ChatGPT mobile app, now available for iOS and Android users. This update allows subscribers to manage development tasks remotely, view live environments, and switch between threads directly from their mobile devices. The integration enhances Codex's functionality, which previously included desktop and browser support, by enabling real-time monitoring and task management on mobile platforms. This move comes amid growing competition with Anthropic, which launched a similar feature, Remote Control, for its Claude Code earlier this year. Both companies are rapidly advancing their AI programming tools, aiming to capture a larger share of the market among enterprises and technical professionals.
