Gemini CLI Setup Guide

更新日: 2026-06-06

Overview

Gemini CLI is Google’s command-line AI assistant. By configuring Crazyrouter’s Gemini-native endpoint, you can use Gemini models that have been verified with real requests in Crazyrouter production.

Configuration

Environment Variables

In the current Gemini CLI release, API-key mode still requires GEMINI_API_KEY to be present explicitly. For Crazyrouter’s Gemini-native endpoint, set these three variables together:

export GEMINI_API_KEY=sk-xxx
export GEMINI_MODEL=gemini-3.1-pro
export GOOGLE_GEMINI_BASE_URL=https://api.crazyrouter.com

PowerShell:

$env:GEMINI_API_KEY="sk-xxx"
$env:GEMINI_MODEL="gemini-3.1-pro"
$env:GOOGLE_GEMINI_BASE_URL="https://api.crazyrouter.com"

If you want this to persist across sessions, put the same values into ~/.gemini/.env or your PowerShell profile.

Configuration File

Edit ~/.gemini/settings.json:

{
  "security": {
    "auth": {
      "selectedType": "gemini-api-key"
    }
  },
  "apiKey": "sk-xxx",
  "baseUrl": "https://api.crazyrouter.com",
  "model": {
    "name": "gemini-3.1-pro"
  }
}

Notes:

Do not leave the auth mode as oauth-personal, or the CLI will continue trying Google sign-in.
Do not write model as a plain string in current versions; use model.name.
In some CLI paths, settings.json alone is not enough. Headless mode may still require the GEMINI_API_KEY environment variable.

`~/.gemini/.env` Example

GEMINI_API_KEY=sk-xxx
GEMINI_MODEL=gemini-3.1-pro
GOOGLE_GEMINI_BASE_URL=https://api.crazyrouter.com

Recommended Model

Model	Description
`gemini-3.1-pro`	Verified successfully with a real Gemini CLI request in Crazyrouter production on April 8, 2026, and recommended as the current baseline

Crazyrouter supports both the Gemini native API format and the OpenAI-compatible format. Gemini CLI uses the Gemini-native format. The gemini-3.1-pro example above, the gemini-api-key auth mode, and GOOGLE_GEMINI_BASE_URL=https://api.crazyrouter.com have been validated with a real CLI request.
