OpenAI Brings Codex to ChatGPT Mobile App for All Users

OpenAI has integrated its Codex coding tool directly into the ChatGPT mobile app. This means users on both iOS and Android, and across all subscription plans, can now manage coding projects remotely. You can review outputs, approve commands, switch models, or start new projects right from your phone. This update follows recent upgrades to Codex, including desktop automation and a Chrome extension. OpenAI's move comes amid increasing competition with Anthropic, which released a similar remote control feature for Claude Code earlier this year. The bottom line is that coding tools are becoming more flexible and accessible for developers.
