Codex is going mobile. The AI-powered coding tool — which OpenAI launched approximately a year ago — has now been integrated into the ChatGPT app, allowing users to monitor and manage their development workflows remotely from their handheld devices.
The new functionality enables users to see their Codex live environments on any device where it is currently running. OpenAI announced these changes on Thursday; the update, which is currently in preview, is now available to all user plans across both iOS and Android platforms.
“This is more than the ability to remotely control a single task or dispatch new tasks to your computer,” OpenAI said in a statement. “From your phone, you can work across all of your threads, review outputs, approve commands, change models, or start something new.”
This mobile expansion follows a string of updates aimed at boosting Codex's autonomy. Last month, OpenAI granted Codex the ability to run in the background in desktop environments, empowering the tool to handle various tasks autonomously. Earlier this month, the company also introduced a Chrome extension that allows the agent to operate within live browser sessions.
The move comes as competition in the space heats up. In February, Anthropic released a similar feature called "Remote Control," which allows users to remotely monitor Claude Code’s progress from afar. The flurry of feature releases from both OpenAI and Anthropic speaks to the tense competition between the two over whose agentic coding tool will become the industry standard. Over the past year, Anthropic’s Claude Code has seen a surge in popularity among businesses and tech professionals, though both tools remain pillars of the current AI coding ecosystem.
