# Gemini CLI

> Complete Guide to Accessing Z.AI GLM Models Using a Customized Gemini CLI

Gemini CLI is a command-line interface tool that can be made compatible with Z.AI's GLM models by using a customized fork.

## Step 1: Obtaining the Custom Version

### 1. Cloning the Custom Repository

Since the official Gemini CLI repository only supports Google's Gemini models, we need to use a customized branch that supports OpenRouter compatibility:

```bash theme={null}
git clone https://github.com/heartyguy/gemini-cli  
cd gemini-cli  
```

### 2. Switching to the Compatible Branch

```bash theme={null}
git checkout feature/openrouter-support  
```

## Step 2: Environment Configuration

### 1. Setting Environment Variables

Configure the API base URL:

```bash theme={null}
export OPENROUTER_BASE_URL="https://api.z.ai/api/coding/paas/v4"  
```

Configure the API Key:

```bash theme={null}
export OPENROUTER_API_KEY="your_api_key"  
```

## Step 3: Installation and Launch

### 1. System Requirements

Ensure your Node.js version is >= 18.

### 2. Installing Dependencies

```bash theme={null}
npm install  
```

### 3. Launch Process

2. User login (recommended to use a Google account for authentication, which will redirect to a webpage for verification).

## Step 4: Usage Results
