qianfan4j：千帆 Java SDK

License JDK17+ LLM-文心一言

qianfan4j是一个开源的千帆大模型平台的非官方Java客户端，基于JDK17构建。它旨在提供一个功能丰富、易于集成和使用的Java库，以便开发者能够通过千帆API轻松实现对话、续写、向量嵌入和图像处理等功能。

请注意：在使用qianfan4j时，你需要遵守千帆API的使用条款和条件。

一、主要功能

qianfan4j支持以下千帆API功能：

  • 对话（Chat）

    • 提供用户与千帆模型进行自然语言对话。
    • 支持用户在一次对话中触发多个函数调用。

  • 续写（Completions）

    • 提供文本续写功能，可以根据给定的文本片段生成后续内容。

  • 向量（Embeddings）

    • 将文本转换为向量表示，用于文本相似度比较、聚类等任务。

  • 图像（Images）

    • 图生文： 根据提供的图像生成描述性文本。
    • 文生图： 将文本描述转换为相应的图像。

  • 插件应用（Plugin）

    • 知识库： 让开发者（甚至非技术人员）以简单的方式管理数据集，包括分片、清洗、向量计算等能力。
    • 智慧图问： 图片理解识别，并对图片内容进行总结概述，输出用户可理解的句子或段落。
    • 百度搜索： 百度搜索插件,实时获取新闻、股票信息等
    • 网页解析： 从任何网页链接获取所需文本信息
    • 天气查询： 输入地址，给出当前该地址天气；输入地址+时间，给出该地址时间段内的天气

二、系统要求

  1. JDK17或更高版本

三、跑通测试

  1. 到百度智能云上注册一个账号
  2. 在百度智能云上创建一个应用，你将会得到一个API Key和一个Secret Key
  3. 声明环境变量： 
    export QIANFAN_AK=<YOUR APP-KEY>
export QIANFAN_SK=<YOUR SECRET-KEY>
    注意：PluginAppTestCase 测试用例如果要跑通，需要在千帆大模型平台创建插件应用，开通ocr-chat插件。 并在配置文件中追加一行 
    export QIANFAN_PLUGIN_APP_ID=<YOUR PLUGIN-APP ID>
  4. 运行测试用例：mvn test

四、依赖使用

项目仓库托管在Maven中央仓库，你可以在pom.xml中添加以下依赖：

<dependency>
    <groupId>io.github.oldmanpushcart</groupId>
    <artifactId>qianfan4j</artifactId>
    <version>1.0.0</version>
</dependency>

创建客户端

// 线程池
final var executor = Executors.newFixedThreadPool(10);

// 千帆客户端
final var client = QianFanClient.newBuilder()
    .ak("***") // API Key
    .sk("***") // Secret Key
    .executor(executor)
    .connectTimeout(Duration.ofSeconds(30))
    .build();

对话示例

// 对话请求
final var request = ChatRequest.newBuilder()
    .model(ChatModel.ERNIE_V4)
    .messages(Message.ofUser("hello!"))
    .build();

// 对话响应
final var response = client.chat(request)
    .async()
    .join();

// System.out.println(response);

输出结果

你好！很高兴与你交流。有什么我可以帮助你的吗？请随时告诉我。

函数调用示例

在qianfan4j中进行函数的声明将会变成一个非常简单的事情。框架自动帮你完成了函数的声明和参数的解析。这样，你就可以专注于函数的实现，而不用再去关心函数的声明和参数的解析了。

函数声明

@ChatFn(name = "echo", description = "echo words", examples = {
    @ChatFn.Example(
        question = "echo: words",
        thoughts = "当用户输入echo:开头的消息时，机器人会原样返回用户输入的消息",
        arguments = """
            {
                "words": "hello, world"
            }
            """
    )
})
public class EchoFunction implements ChatFunction<EchoFunction.Echo, EchoFunction.Echo> {

    @Override
    public CompletableFuture<Echo> call(Echo echo) {
        return CompletableFuture.completedFuture(new Echo(echo.words()));
    }

    public record Echo(String words) {

    }

}

对话触发函数调用

final var request = ChatRequest.newBuilder()
    .model(ChatModel.ERNIE_V4)
    .functions(new EchoFunction())
    .messages(Message.ofUser("echo: HELLO WORLD!"))
    .build();

final var response = client.chat(request)
    .async()
    .join();

// System.out.println(response.content());

输出结果

您好，您输入的消息是：HELLO WORLD!，我已原样返回。请问有其他需要吗？

多函数调用示例

qianfan4j会根据LLM的推理能力，自动拆解多函数调用的任务，然后按照拆解的任务顺序依次调用函数。这样，你就可以专注于函数的实现，而不用再去关心函数的调用顺序了。 我们假设有两个函数 QueryScoreFunction和 ComputeAvgScoreFunction，分别用于查询成绩和计算平均分。我们可以通过以下方式实现多函数调用：

final var request = ChatRequest.newBuilder()
    .model(ChatModel.ERNIE_V4)
    .functions(new QueryScoreFunction(), new ComputeAvgScoreFunction())
    .option(ChatOptions.IS_STREAM, true)
    .option(ChatOptions.IS_ENABLE_SEARCH, false)
    .option(ChatOptions.TEMPERATURE, 0.01f)
    .messages(Message.ofUser("计算李四的语文和数学平均分"))
    .build();

final var response = client.chat(request)
    .async()
    .join();

// System.out.println(response.content());

根据您的要求，我已经使用[compute_avg_score]工具计算了李四的平均分。他的平均分是75.0分。如果您还有其他问题或需要更详细的信息，请随时告诉我。

在一次对话中，qianfan4j根据用户的需求，使用了query_score工具来查询李四的语文和数学成绩，分别是80分和70分， 然后使用compute_avg_score工具来计算他们的语文平均分。最终，助手返回了李四的语文和数学平均分为75分。

文生图示例

qianfan4j会将文心一言返回的BASE64编码封装为BufferedImage类型，方便开发者进行后续的图像处理。 下面是一个简单的示例，展示了如何使用qianfan4j进行图像处理：

final var request = GenerationImageRequest.newBuilder()
    .model(GenerationImageModel.STABLE_DIFFUSION_XL)
    .prompt("猫")
    .negative("白色")
    .option(GenerationImageOptions.NUMBERS, 2)
    .option(GenerationImageOptions.SIZE, GenerationImageRequest.Size.S_1024_1024)
    .build();

final var response = client.generationImage(request)
    .async()
    .join();

然后你就可以通过response.images().get(0)拿到生成的图片的BufferedImage类型进行后续操作了。

六、特别致谢

首先，我要向百度千帆大模型团队的同学们表达我最深切地感谢。正是他们不懈的努力和卓越的工作成果，使得我们能够如此便捷地利用千帆的API使用文心一言在内的LLM大模型进行开发。 他们为整个开发者社区树立了榜样，推动了技术的进步。

关于文心一言

作为个人使用者，我对文心一言这个产品怀有极高地评价。相较于OpenAi的GPT-4，虽然在某些功能上还有待完善，但文心一言在稳定性方面展现出了显著的优势。 在实际应用中，它的可靠和稳定让我倍感信赖，这也是我选择它作为开发基础的重要原因之一。

同时我也希望在多模态的时代，千帆大模型平台和文心一言不要落后。

缘起与动机

当我得知千帆大模型发布了SDK时，我迫不及待地想要集成到我的项目中。然而，我遗憾地发现他们的SDK当时并不支持Java。 作为一个Java开发者，我深知Java在开发者社区中的普及程度和重要性。因此，我决定自己动手，填补这一空白，为Java开发者提供一个方便、易用的文心一言客户端。

正是在这样的背景下，我发起了qianfan4j项目。它旨在成为文心一言的Java开发者最佳伴侣，提供简洁明了的API接口，帮助开发者快速集成和使用文心一言的功能。 通过qianfan4j，Java开发者可以轻松地实现对话、续写、向量嵌入和图像处理等功能，极大地提升了开发效率和用户体验。

展望与呼吁

展望未来，我希望qianfan4j能够成为Java开发者与千帆大模型平台之间的桥梁，推动千帆和文心一言在更多领域的应用和发展。 同时，我也呼吁更多的开发者加入到qianfan4j的开源社区中来，共同完善和优化这个项目，让它更好地服务于整个开发者社区。
