Gemini CLI

Google Gemini CLI supports an openai-flavoured auth mode, which makes it a drop-in client for PrimeRouter.

One-line installer

Windows PowerShell

irm https://primerouter.ai/install/gemini-cli.ps1 | iex

macOS / Linux / WSL

curl -fsSL https://primerouter.ai/install/gemini-cli.sh | bash

💡 The script writes ~/.gemini/settings.json (backs up the existing file first, then chmod 600), sets selectedAuthType to openai, and fills in PrimeRouter's baseUrl + your apiKey. Default model is gemini-2.5-pro; override with PRIMEROUTER_MODEL=<your-model>.

Run:

gemini

Fallback: manual install
