Gemini CLI Setup

Gemini CLI is Google’s command-line tool for Gemini models. With OfoxAI, you can use the Gemini protocol while gaining access to a broader model selection.

Setup Steps

1. Install Gemini CLI


npm install -g @google/gemini-cli

2. Configure OfoxAI

Gemini CLI uses the Gemini native protocol. Point it to OfoxAI via the configuration file:

~/.gemini/settings.json


{
  "apiKey": "<your OFOXAI_API_KEY>",
  "baseUrl": "https://api.ofox.ai/gemini"
}

Or use environment variables:

~/.zshrc


export GEMINI_API_KEY=<your OFOXAI_API_KEY>

The base URL configuration method for Gemini CLI may change with version updates. If the above method doesn’t work, refer to the latest Gemini CLI documentation.

3. Verify


gemini "Hello, tell me about yourself"
