The ChatGPT/Codex app bundles a full copy of LibreOffice

The OpenAI Codex desktop application, now called ChatGPT, stores a 1.7 GB “codex-primary-runtime” directory in ~/.cache, containing a complete Python interpreter, a full Node.js runtime, and native binaries for Poppler, git, and the LibreOffice suite. These binaries are accessed via plugins in ~/.cache/codex-runtimes/codex-primary-runtime/plugins/openai-primary-runtime/plugins/documents, which provide the skills needed for Codex to locate and use them.
