OpenAI Launches Codex App for Mac With Multi-Agent Coding [Video]

OpenAI has officially launched the Codex app for macOS, a dedicated desktop interface designed to rethink how developers manage AI-assisted coding. Rather than a simple chat window, the new app acts as a "command center" for orchestrating multiple coding agents at once, allowing users to delegate complex, long-running tasks without tying up their main workflow.



The release addresses a growing pain point in AI-assisted development: managing multiple parallel tasks. The Codex app allows developers to run agents simultaneously across different projects. It also includes built-in support for git worktrees. This means each agent operates on an isolated copy of the code, letting the AI experiment, make changes, or fix bugs without affecting the developer's local state or creating merge conflicts in the main branch.


This move toward a more integrated desktop experience follows OpenAI's recent pattern of treating the Mac as a priority platform. We've seen this with the release of the ChatGPT Atlas browser and the deeper system integration following the acquisition of the Sky app.

Beyond writing code, OpenAI is equipping Codex with "skills" that let it interact with other tools. Out of the box, the app includes a library of skills for workflows like fetching designs from Figma to generate UI code, managing tickets in Linear, or deploying web apps directly to Vercel. It also taps into ChatGPT Images to generate assets on the fly.

OpenAI also introduced "Automations," a feature that lets Codex run background tasks on a schedule. This is aimed at repetitive maintenance work, such as daily bug triage or summarizing continuous integration failures, with the results landing in a queue for human review later. To keep things secure while the AI works in the background, the app uses a configurable, system-level sandbox that restricts file access to specific folders and requires permission for sensitive actions like network requests.

The engine behind the app is the recently released GPT-5.2, which OpenAI says delivers major gains in coding proficiency. Since that model launched in December, OpenAI reports that Codex usage has doubled.


The Codex app is available for download on macOS starting today. It is included with ChatGPT Plus, Pro, Business, Enterprise, and Edu subscriptions. For a limited time, OpenAI is also opening access to users on the Free and ChatGPT Go plans. To encourage heavy use during the launch window, rate limits for Codex have been doubled for all paid subscribers.
