Multiple AI agents orchestrating with OpenAI's Codex app

OpenAI's new Codex app offers developers a central user interface for multiple Codex agents, including projects, capabilities, and automations. For now, the app is only available as a desktop application for macOS. The central AI agent behind the app is the AI tool Codex of the same name.

Parallel to the launch of the Codex app, Codex is included for a limited time in the ChatGPT plans Free and Go. OpenAI does not specify exactly how long. For the Plus, Pro, Business, Enterprise, and Edu plans, the provider is doubling the usage limits. These are intended to apply wherever Codex is used, which includes IDEs or the cloud in addition to the new app.

Delegate Instead of Program

While the AI tool Codex, released in 2025, can take over some programming work for software developers, the newly introduced app takes a more comprehensive approach. It is intended to enable developers to handle complex and time-consuming multitasking tasks across entire teams of agents without losing track.

For delegating workflows, the AI tool provides threads organized by project in addition to automatic schedules, allowing multiple agents to run in parallel and exchange tasks. It also supports Git Worktrees, which allows agents to work on the same repository simultaneously and without conflicts. To make it easier for developers to get started, the Codex app takes over session histories and configurations from the Codex-CLI and IDE extensions.

A library of functions (skills) for tools and workflows is also part of the app's scope. This allows, for example, web apps to be uploaded to cloud hosts, images to be generated, documentation to be created, or designs to be implemented. A complete list can be found in OpenAI's repository.

Like the Codex-CLI, the Codex app also uses system-wide and configurable sandbox mechanisms. Agents are restricted to editing files only within isolated copies. Actions that require higher permissions, such as network access, are only performed after explicit permission has been granted. For automation, certain commands can be executed with elevated privileges. OpenAI plans for Codex to run continuously in the background in the future, cloud-based, even when users have turned off their computers.

As an example of the Codex app's work, OpenAI shows a racing game that Codex developed itself over multiple iterations with a total of 7 million tokens after prompt input. The tool also took on the roles of designers and QA testers and played the game itself.

Windows and Linux users can register with OpenAI and will be notified by email as soon as the app is released for these platforms.
