Qwen Code is a powerful command-line AI workflow tool adapted from [**Gemini CLI**](https://github.com/google-gemini/gemini-cli) ([details](./README.gemini.md)), specifically optimized for [Qwen3-Coder](https://github.com/QwenLM/Qwen3-Coder) models. It enhances your development workflow with advanced code understanding, automated tasks, and intelligent assistance.

## 💡 Free Options Available

Get started with Qwen Code at no cost using any of these free options:

### 🔥 Qwen OAuth (Recommended)

- **2,000 requests per day** with no token limits
- **60 requests per minute** rate limit
- Simply run `qwen` and authenticate with your qwen.ai account
- Automatic credential management and refresh
- Use `/auth` command to switch to Qwen OAuth if you have initialized with OpenAI compatible mode

### 🌏 Regional Free Tiers

- **Mainland China**: ModelScope offers **2,000 free API calls per day**
- **International**: OpenRouter provides **up to 1,000 free API calls per day** worldwide

For detailed setup instructions, see [Authorization](#authorization).

> [!WARNING]
> **Token Usage Notice**: Qwen Code may issue multiple API calls per cycle, resulting in higher token usage (similar to Claude Code). We're actively optimizing API efficiency.

## Key Features

- **Code Understanding & Editing** - Query and edit large codebases beyond traditional context window limits
- **Workflow Automation** - Automate operational tasks like handling pull requests and complex rebases
- **Enhanced Parser** - Adapted parser specifically optimized for Qwen-Coder models

## Installation

### Prerequisites

Ensure you have [Node.js version 20](https://nodejs.org/en/download) or higher installed.

```bash
curl -qL https://www.npmjs.com/install.sh | sh
```

### Install from npm

```bash
npm install -g @qwen-code/qwen-code@latest
qwen --version
```

### Install from source

```bash
git clone https://github.com/QwenLM/qwen-code.git
cd qwen-code
npm install
npm install -g .
```

## Quick Start

```bash
# Start Qwen Code
qwen

# Example commands
> Explain this codebase structure
> Help me refactor this function
> Generate unit tests for this module
```

### Session Management

Control your token usage with configurable session limits to optimize costs and performance.

#### Configure Session Token Limit

Create or edit `.qwen/settings.json` in your home directory:

```json
{
  "sessionTokenLimit": 32000
}
```

#### Session Commands

- **`/compress`** - Compress conversation history to continue within token limits
- **`/clear`** - Clear all conversation history and start fresh
- **`/stats`** - Check current token usage and limits

> 📝 **Note**: Session token limit applies to a single conversation, not cumulative API calls.

### Authorization

Choose your preferred authentication method based on your needs:

#### 1. Qwen OAuth (🚀 Recommended - Start in 30 seconds)

The easiest way to get started - completely free with generous quotas:

```bash
# Just run this command and follow the browser authentication
qwen
```

**What happens:**

1. **Instant Setup**: CLI opens your browser automatically
2. **One-Click Login**: Authenticate with your qwen.ai account
3. **Automatic Management**: Credentials cached locally for future use
4. **No Configuration**: Zero setup required - just start coding!

**Free Tier Benefits:**

- ✅ **2,000 requests/day** (no token counting needed)
- ✅ **60 requests/minute** rate limit
- ✅ **Automatic credential refresh**
- ✅ **Zero cost** for individual users
- ℹ️ **Note**: Model fallback may occur to maintain service quality

#### 2. OpenAI-Compatible API

Use API keys for OpenAI or other compatible providers:

**Configuration Methods:**

1. **Environment Variables**

   ```bash
   export OPENAI_API_KEY="your_api_key_here"
   export OPENAI_BASE_URL="your_api_endpoint"
   export OPENAI_MODEL="your_model_choice"
   ```

2. **Project `.env` File**
   Create a `.env` file in your project root:
   ```env
   OPENAI_API_KEY=your_api_key_here
   OPENAI_BASE_URL=your_api_endpoint
   OPENAI_MODEL=your_model_choice
   ```

**API Provider Options**
