 `ori` is the odd one out: it runs the other harnesses against OpenRouter's whole model catalog, so `ori claude`, `ori codex`, or `ori opencode` start those agents on whichever model you point them at, and `ori code` is Ori's own agent.

+The _Install > AI_ menu also carries a few graphical AI apps: the ChatGPT desktop app, Grok Bot for chatting with xAI's models, and Hermes Desktop.

+Hermes Desktop is the one to know about, because there is only ever one Hermes on a machine. The app only runs against a runtime built from its own commit, so it installs one of its own under `~/.hermes` on first launch, which takes a few minutes and shows its own progress. From then on that is the Hermes the terminal `hermes` command and the default agent use too, whichever order you installed them in. Removing the app under _Remove > AI_ takes that runtime with it, and keeps your chats, memories, and the skills Hermes wrote for itself.
