+title: QwQ (Alibaba Cloud)
+---
+
+[QwQ](https://github.com/yigit353/langchain-qwq) provides seamless integration between LangChain and QwQ models as well as other Qwen series models from Alibaba Cloud BaiLian (via OpenAI-compatible API).
+
+QwQ models feature advanced reasoning capabilities with direct access to internal model reasoning and thinking content.
+
+## Installation and Setup
+
+Install the integration package:
+
+<CodeGroup>
+```bash pip
+pip install langchain-qwq
+```
+
+```bash uv
+uv add langchain-qwq
+```
+</CodeGroup>
+
+Request an API key from [Alibaba Cloud DashScope](https://dashscope.console.aliyun.com/) and set it as an environment variable:
+
+```bash
+export DASHSCOPE_API_KEY=your_api_key
+```
+
+<Note>
+    Domestic Chinese users should configure `DASHSCOPE_API_BASE` to the domestic endpoint, as `langchain-qwq` defaults to the international Alibaba Cloud endpoint.
+</Note>
+
+## Chat models
+
+The package provides two main chat model classes:
+
+### ChatQwQ
+
+For QwQ and QvQ models with built-in reasoning capabilities:
+
+```python
+from langchain_qwq import ChatQwQ
+
+model = ChatQwQ(model="qwq-plus")
+response = model.invoke("Hello, how are you?")
+```
+
+### ChatQwen
+
+For Qwen3 series models and other Qwen models:
+
+```python
+from langchain_qwq import ChatQwen
+
+model = ChatQwen(model="qwen-max")
+response = model.invoke("Hello, how are you?")
+```
+
+## Features
+
+- **QwQ Model Integration**: Full support for QwQ models with advanced reasoning capabilities
+- **Qwen3 Model Integration**: Comprehensive support for Qwen3 series models with hybrid reasoning modes
+- **Other Qwen Models**: Compatibility with Qwen-Max, Qwen2.5, and other Qwen series models
+- **Vision Models**: Native support for Qwen-VL series vision models
+- **Streaming Support**: Synchronous and asynchronous streaming capabilities
