OpenAI’s Codex is now in the ChatGPT mobile app

OpenAI has expanded access to Codex, its AI-powered coding tool, by integrating it into the ChatGPT mobile app for both iOS and Android devices. Users can now remotely instruct Codex on their desktop to perform tasks, such as writing code or running applications, directly from their phones. The feature allows users to manage threads, review outputs, approve commands, and switch models while receiving real-time updates like screenshots, terminal results, and test outputs. The integration ensures that sensitive data—files, credentials, permissions, and local setups—remains secure on the machine running Codex, with updates flowing back to the mobile app. This preview is available to all ChatGPT users, including those on the free and Go plans, marking a significant step toward OpenAI’s vision of a desktop 'superapp.' The move follows OpenAI’s recent focus on strengthening its enterprise offerings and responding to competition, particularly from Anthropic’s Claude Code. While the company has scaled back on some projects, such as its Sora video-generation tool, the Codex update reflects its commitment to enhancing productivity tools for developers and businesses. This feature builds on a recent major update to Codex, which now supports macOS app operations, further solidifying its role as a versatile AI assistant for coding tasks. OpenAI’s integration of Codex into ChatGPT underscores its strategy to make advanced AI tools more accessible across devices, bridging the gap between mobile convenience and desktop functionality.
