OpenAI Brings ChatGPT and Codex to Linux in Public Preview
The new desktop build supports five current Ubuntu, Debian and Fedora releases worldwide, with browser actions enabled but control of other Linux applications still unavailable.
OpenAI added a Linux edition of the ChatGPT and Codex desktop app in public preview on August 14. The global release gives Linux users an official desktop route into both conversational work and coding-agent tasks, but the first version stops short of controlling other applications on the operating system.
The preview matters most to developers and technical teams that work primarily on Linux. They can now use the same desktop product family already offered on macOS and Windows without moving the workflow into a browser-only session or a different operating system. Public preview status also signals that platform coverage has expanded before OpenAI has declared the Linux build generally available.
Five distribution releases are supported
OpenAI lists Ubuntu 24.04 LTS and 26.04 LTS, Debian 13, and Fedora 43 and 44 as the supported operating-system releases. The company describes the app as globally available, rather than limiting the preview to a particular country or paid plan in the release note.
That list gives teams a concrete compatibility boundary. An organization using an older long-term-support image, another Linux distribution or a custom desktop environment should not infer support from the broader Linux label. OpenAI has not published a wider compatibility matrix, package-maintenance timetable or date for general availability in the fetched evidence.
The preview includes ChatGPT and Codex in one desktop application. That puts conversational assistance and software-development tasks in the same installed client, consistent with OpenAI's broader desktop direction, while the Linux announcement itself is narrowly about platform availability and current control surfaces.
Browser actions arrive before desktop-app control
The Linux app can work through its built-in browser or Chrome. OpenAI says browser actions are available, allowing supported web workflows to run from the desktop client. The company also states that control of other desktop applications is not supported yet.
That distinction prevents the preview from being mistaken for full Linux computer use. A browser task and an operating-system task have different permission and failure boundaries. The first can act inside supported web pages and browser sessions. The second would require interaction with native windows, local applications and broader desktop state, which this release does not claim to provide.
For security and operations teams, the current boundary is useful information. Browser automation still needs careful account, session and approval controls, but it is a narrower surface than general control over every application on a workstation. The preview does not remove the need to review the app's permissions, connected accounts or any action proposed by an agent.
What teams should test
A public preview is an opportunity to measure practical compatibility rather than assume parity with mature clients. Linux users should verify installation and update behavior on the exact supported distribution, test browser workflows against their own sites, and confirm how authentication, local files and organizational policy behave in their environment.
The release note does not provide reliability data, enterprise deployment tooling, independent security testing or a roadmap for native desktop control. It also does not say when more distributions will be added. Those omissions do not negate the release, but they keep the evidence at one official product announcement and internal confidence at medium.
Status
Confirmed. OpenAI's official ChatGPT release notes establish the Linux public preview, the five named distribution releases, global availability and the browser-versus-desktop control boundary.
