Quick CLI setup

Pick your CLI. Install it first (step 1), then run the config command (step 2) to write the config file for this model.

Operating system

Step 1 — Install the CLI first (if not installed)

Skip this if you already have the CLI installed.

Step 2 — Config command (run once)

Open Terminal (macOS/Linux) or PowerShell (Windows), paste the command, then enter your API key when prompted.

Uninstall — remove config & CLI

Run one command to restore your previous config (or remove the CKEY config) and see how to uninstall the CLI.
