ChatGPT in Beta on Linux: Reported Limitations and Issues

⚡

Key Takeaways

1The Linux pre-release of ChatGPT is proprietary, built on Electron, distributed in DEB and RPM formats

2Announced support: Ubuntu 24.04/26.04 LTS, Debian 13, Fedora 43/44 on x86-64 and Arm64

3Users report >1 GB of RAM at idle and a project list bug

💡Why it matters — The arrival of a Linux client completes the presence on major desktop OSs and opens a unified workspace with integrations, while also highlighting limitations at this stage.

The test version of the ChatGPT desktop client for Linux is available, but feedback indicates a bug with the project list and significant memory consumption. The proprietary client, built on Electron, combines ChatGPT, ChatGPT Work, and Codex, aiming for a unified workspace. The announced support covers Ubuntu 24.04 LTS and 26.04 LTS, Debian 13, and Fedora 43 and 44, on x86-64 and Arm64, with DEB and RPM packages.

High Memory Usage and Shell Projects Missing from the List

Users report that the application, even when inactive, can exceed one gigabyte of RAM. One user noted that after a few hours of moderate use, a computer equipped with 16 GB of RAM ran out of memory, causing virtual memory to render the machine almost unusable. This same tester found that their ChatGPT shell sessions were not visible in the application's project list, a situation also reported by others.

Default Access Restricted to Data and Services

Upon launch, the Linux client does not automatically scan all local disks, folders, or applications. It also does not control arbitrary Linux GUI applications through native computer usage. It does not access an online service simply because the user has an account; a permitted browser connection, a plugin or integration, uploaded data, or an explicit task or action must be provided.

Connectors Available with Messaging and Suites

The client supports integration with Google Calendar, Gmail, Outlook, Teams, Slack, and Google Drive. After establishing these connections, the user has access to messages, emails, calendars, documents, and project tracking tools directly from the application.

Linux Pre-release, Functional Scope, and Distribution

OpenAI has made a preliminary version of its ChatGPT client available for Linux. This proprietary application, based on Electron, includes ChatGPT, ChatGPT Work, and Codex; according to OpenAI, it is designed as a workspace to manage projects, files, browser workflows, and Codex sessions. According to a tester, Codex is the main asset for developers, and they believe the publisher is thus offering a native client for major desktop environments. Regarding systems, the pre-release supports Ubuntu 24.04 LTS and 26.04 LTS, Debian 13, and Fedora 43 and 44, on both x86-64 and Arm64. OpenAI provides DEB and RPM packages, and a tester notes that the application works practically on most distributions derived from Debian and Red Hat, such as Linux Mint.

A Test Reveals Incorrect Responses and Suggests Safeguards

On a Linux Mint machine, a tester asked the application for the specifications of the Starmind AI datacenter satellites from SpaceX and Nvidia. The response indicated 20 m in height and 70 m in wingspan, while SpaceX lists 30 m and 75 m. The tester concluded that ChatGPT remains inaccurate and recommends several adjustments: keep the model enhancement option disabled, use temporary discussions for sensitive queries (30-day deletion window), limit the application's access to a dedicated project directory, and avoid exposing ~/, the document tree, or folders containing credentials and source code. They also advise keeping Codex on "Request Approval" and only enabling "Full Access" when necessary. The same tester believes significant improvements are needed before the application is truly useful for Linux users and prefers to use the browser for now. However, they anticipate that this offering could strengthen OpenAI's presence on developers' desktops.
