CLI
Every louped command.
Every command takes --help, and most are also forms on the app's Launch page. Commands find the
project by looking for louped.toml in the current folder and its parents.

LOUPED_EXPERIMENTS | experiments/ in the project |
LOUPED_SYSTEM_METRICS=0 | Turns off hardware sampling |
LOUPED_REMOTE | remote in louped.toml |
HF_TOKEN | The hf auth login token |
The first louped push or louped pull in a project with no remote asks for one. Press Enter
for a private Hugging Face bucket of your own. It also asks for a Hugging Face token when an
hf:// remote finds none, and saves the remote to louped.toml.
louped serve --host needs --expose. An exposed server is read-only: no launching or model
loading.
