OpenAI launches ChatGPT desktop app for Linux

OpenAI has launched a dedicated ChatGPT desktop app for Linux in preview, completing its major desktop operating system coverage. Released on August 11, 2026, the app bundles ChatGPT, ChatGPT Work, and the Codex coding agent into a single package. It officially supports Ubuntu 24.04/26.04 LTS, Debian 13, and Fedora 43/44 across x64 and ARM64 architectures. This release intensifies OpenAI's rivalry with Anthropic, which launched its Claude desktop app for Linux one month prior.
