# DashScope

[DashScope](https://dashscope.aliyun.com/) is a platform developed by [Alibaba Cloud](https://www.alibabacloud.com/).
It provides an interface for model visualization, monitoring, and debugging, particularly when working with AI/ML
models in production environments. The platform allows users to visualize performance metrics, track model behavior, and
identify potential issues early on in the deployment cycle.

[Qwen](https://tongyi.aliyun.com/) models are a series of generative AI models developed
by [Alibaba Cloud](https://www.alibabacloud.com/). The Qwen family of models are specifically designed for tasks like
text generation, summarization, question answering, and various NLP tasks.

You can refer
to [DashScope Document](https://help.aliyun.com/zh/model-studio/getting-started/?spm=a2c4g.11186623.help-menu-2400256.d_0.6655453aLIyxGp)
for more details. LangChain4j integrates with DashScope by
Using [DashScope Java SDK](https://help.aliyun.com/zh/dashscope/java-sdk-best-practices?spm=a2c4g.11186623.0.0.272a1507Ne69ja)

## Maven Dependency

:::note
Since `1.0.0-alpha1`, `langchain4j-dashscope` has migrated to `langchain4j-community` and is renamed to
`langchain4j-community-dashscope`.
:::

Before `1.0.0-alpha1`:

```xml

<dependency>
    <groupId>dev.langchain4j</groupId>
    <artifactId>langchain4j-dashscope</artifactId>
    <version>${previous version here}</version>
</dependency>
```

`1.0.0-alpha1` and later:

```xml

<dependency>
    <groupId>dev.langchain4j</groupId>
    <artifactId>langchain4j-community-dashscope</artifactId>
    <version>${latest version here}</version>
</dependency>
```

Or, you can use BOM to manage dependencies consistently:

```xml

<dependencyManagement>
    <dependency>
        <groupId>dev.langchain4j</groupId>
        <artifactId>langchain4j-community-bom</artifactId>
        <version>${latest version here}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
</dependencyManagement>
```
