The ChatGPT/Codex app bundles a full copy of LibreOffice

The OpenAI ChatGPT desktop app (formerly called Codex) includes a 1.7GB cache folder containing a full copy of LibreOffice along with complete Python and Node.js installations and native binaries for tools like Poppler and git. The app uses these bundled components through skills that enable it to locate and utilize these binaries for document handling and other functions.
