OpenAI today officially released the official Codex application for the Windows platform, providing developers with native AI programming assistants and enhancing security through a specially built open source local agent sandbox. Last month, OpenAI first launched the Codex application on macOS, bringing developers more convenient multi-agent management and long-term task collaboration capabilities. Since then, the developer community has been calling for the launch of a native Windows version.

Unlike macOS, Codex needs to strictly limit the scope of access to the file system on Windows, so it is more difficult to implement. The OpenAI team has been working with Microsoft to solve related problems.
OpenAI has announced that the Windows version of the Codex application is officially online. Developers can download and use it through the Microsoft App Store and experience the full Codex functionality in Windows development environments such as PowerShell. The new application has a built-in native agent sandbox, which provides secure isolation for running intelligent agents in the local environment. To achieve this, OpenAI built the first truly Windows-native agent sandbox, leveraging operating system-level controls such as restricted tokens, file system ACLs, and independent sandbox isolation to ensure that agents run safely in development scenarios.
It is worth noting that this sandbox environment has been released as open source, and anyone can check its implementation details. The industry expects that with the emergence of this open source implementation, other AI vendors such as Anthropic and Google may also launch their own native AI applications on the Windows platform based on the same solution. In terms of functional design, the Windows version of Codex is highly consistent with the macOS version. It also supports running multiple agents at the same time and processing multiple coding tasks in parallel. Each task is executed in its own independent work tree, and code changes are isolated from each other to avoid conflicts. Developers can review differences and suggest changes before merging, and then integrating the final results back into the main code base.
The core capabilities supported by the first official version of Codex for Windows include: supporting parallel work of multiple agents and organizing and managing by project and session; through the built-in work tree and cloud environment, ensuring that different agents can modify the code at the same time without conflict; before merging, you can view the diff in the thread, add comments, and open relevant changes in the local editor; quickly switch between multiple tasks and projects without losing context; expand through "skills" Codex packages tools, scripts, and team agreements into reusable workflows; you can set up scheduled or repeatable automated workflows, and hand over repetitive work to agents; and it can inherit the history and configuration in the Codex CLI and IDE plug-ins, allowing the existing development environment to smoothly transition to desktop applications.
To celebrate the release of Codex for Windows, OpenAI has simultaneously opened up a wider trial of Codex: ChatGPT free version and Go users can now also experience Codex; while paying users such as ChatGPT Plus, Pro, Business, Enterprise and Edu, their Codex request rate limit will be temporarily doubled before April 2.
