ZhiPu AI Chat

Spring AI supports the various AI language models from ZhiPu AI. You can interact with ZhiPu AI language models and create a multilingual conversational assistant based on ZhiPuAI models.

Prerequisites

You will need to create an API with ZhiPuAI to access ZhiPu AI language models.

Create an account at ZhiPu AI registration page and generate the token on the API Keys page. The Spring AI project defines a configuration property named spring.ai.zhipuai.api-key that you should set to the value of the API Key obtained from API Keys page. Exporting an environment variable is one way to set that configuration property:

export SPRING_AI_ZHIPU_AI_API_KEY=<INSERT KEY HERE>

Add Repositories and BOM

Spring AI artifacts are published in Spring Milestone and Snapshot repositories. Refer to the Repositories section to add these repositories to your build system.

To help with dependency management, Spring AI provides a BOM (bill of materials) to ensure that a consistent version of Spring AI is used throughout the entire project. Refer to the Dependency Management section to add the Spring AI BOM to your build system.

Auto-configuration

Spring AI provides Spring Boot auto-configuration for the ZhiPuAI Chat Client. To enable it add the following dependency to your project’s Maven pom.xml file:

<dependency>
    <groupId>org.springframework.ai</groupId>
    <artifactId>spring-ai-zhipuai-spring-boot-starter</artifactId>
</dependency>

or to your Gradle build.gradle build file.

dependencies {
    implementation 'org.springframework.ai:spring-ai-zhipuai-spring-boot-starter'
}
Refer to the Dependency Management section to add the Spring AI BOM to your build file.

List of HTTP status codes that should not trigger a retry (e.g. to throw NonTransientAiException).

empty

spring.ai.retry.on-http-codes

List of HTTP status codes that should trigger a retry (e.g. to throw TransientAiException).

empty

Connection Properties

The prefix spring.ai.zhiPu is used as the property prefix that lets you connect to ZhiPuAI.

Property Description Default

spring.ai.zhipuai.base-url

The URL to connect to

open.bigmodel.cn/api/paas

spring.ai.zhipuai.api-key

The API Key

-

Configuration Properties

The prefix spring.ai.zhipuai.chat is the property prefix that lets you configure the chat model implementation for ZhiPuAI.

Property Description Default

spring.ai.zhipuai.chat.enabled

Enable ZhiPuAI chat model.

true

spring.ai.zhipuai.chat.base-url

Optional overrides the spring.ai.zhipuai.base-url to provide chat specific url

open.bigmodel.cn/api/paas

spring.ai.zhipuai.chat.api-key

Optional overrides the spring.ai.zhipuai.api-key to provide chat specific api-key

-

spring.ai.zhipuai.chat.options.model

This is the ZhiPuAI Chat model to use

GLM-3-Turbo (the GLM-3-Turbo, GLM-4, GLM-4-Air, GLM-4-AirX, GLM-4-Flash, and GLM-4V point to the latest model versions)

spring.ai.zhipuai.chat.options.maxTokens

The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model’s context length.

-

spring.ai.zhipuai.chat.options.temperature

What sampling temperature to use, between 0 and 1. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.

0.7

spring.ai.zhipuai.chat.options.topP

An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both..

1.0

spring.ai.zhipuai.chat.options.stop

The model will stop generating characters specified by stop, and currently only supports a single stop word in the format of ["stop_word1"]

-

spring.ai.zhipuai.chat.options.user

A unique identifier representing your end-user, which can help ZhiPuAI to monitor and detect abuse.

-

spring.ai.zhipuai.chat.options.requestId

The parameter is passed by the client and must ensure uniqueness. It is used to distinguish the unique identifier for each request. If the client does not provide it, the platform will generate it by default.

-

spring.ai.zhipuai.chat.options.doSample

When do_sample is set to true, the sampling strategy is enabled. If do_sample is false, the sampling strategy parameters temperature and top_p will not take effect.

true

spring.ai.zhipuai.chat.options.proxy-tool-calls

If true, the Spring AI will not handle the function calls internally, but will proxy them to the client. Then is the client’s responsibility to handle the function calls, dispatch them to the appropriate function, and return the results. If false (the default), the Spring AI will handle the function calls internally. Applicable only for chat models with function calling support

false
You can override the common spring.ai.zhipuai.base-url and spring.ai.zhipuai.api-key for the ChatModel implementations. The spring.ai.zhipuai.chat.base-url and spring.ai.zhipuai.chat.api-key properties if set take precedence over the common properties. This is useful if you want to use different ZhiPuAI accounts for different models and different model endpoints.
All properties prefixed with spring.ai.zhipuai.chat.options can be overridden at runtime by adding a request specific Runtime Options to the Prompt call.

Runtime Options

The ZhiPuAiChatOptions.java provides model configurations, such as the model to use, the temperature, the frequency penalty, etc.

On start-up, the default options can be configured with the ZhiPuAiChatModel(api, options) constructor or the spring.ai.zhipuai.chat.options.* properties.

At run-time you can override the default options by adding new, request specific, options to the Prompt call. For example to override the default model and temperature for a specific request:

ChatResponse response = chatModel.call(
    new Prompt(
        "Generate the names of 5 famous pirates.",
        ZhiPuAiChatOptions.builder()
            .withModel(ZhiPuAiApi.ChatModel.GLM_3_Turbo.getValue())
            .withTemperature(0.5)
        .build()
    ));
In addition to the model specific ZhiPuAiChatOptions you can use a portable ChatOptions instance, created with the ChatOptionsBuilder#builder().

Sample Controller

Create a new Spring Boot project and add the spring-ai-zhipuai-spring-boot-starter to your pom (or gradle) dependencies.

Add a application.properties file, under the src/main/resources directory, to enable and configure the ZhiPuAi chat model:

spring.ai.zhipuai.api-key=YOUR_API_KEY
spring.ai.zhipuai.chat.options.model=glm-4-air
spring.ai.zhipuai.chat.options.temperature=0.7
replace the api-key with your ZhiPuAI credentials.

This will create a ZhiPuAiChatModel implementation that you can inject into your class. Here is an example of a simple @Controller class that uses the chat model for text generations.

@RestController
public class ChatController {

    private final ZhiPuAiChatModel chatModel;

    @Autowired
    public ChatController(ZhiPuAiChatModel chatModel) {
        this.chatModel = chatModel;
    }

    @GetMapping("/ai/generate")
    public Map generate(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) {
        return Map.of("generation", this.chatModel.call(message));
    }

    @GetMapping("/ai/generateStream")
	public Flux<ChatResponse> generateStream(@RequestParam(value = "message", defaultValue = "Tell me a joke") String message) {
        var prompt = new Prompt(new UserMessage(message));
        return this.chatModel.stream(prompt);
    }
}

Manual Configuration

The ZhiPuAiChatModel implements the ChatModel and StreamingChatModel and uses the Low-level ZhiPuAiApi Client to connect to the ZhiPuAI service.

Add the spring-ai-zhipuai dependency to your project’s Maven pom.xml file:

<dependency>
    <groupId>org.springframework.ai</groupId>
    <artifactId>spring-ai-zhipuai</artifactId>
</dependency>

or to your Gradle build.gradle build file.

dependencies {
    implementation 'org.springframework.ai:spring-ai-zhipuai'
}
Refer to the Dependency Management section to add the Spring AI BOM to your build file.

Next, create a ZhiPuAiChatModel and use it for text generations:

var zhiPuAiApi = new ZhiPuAiApi(System.getenv("ZHIPU_AI_API_KEY"));

var chatModel = new ZhiPuAiChatModel(this.zhiPuAiApi, ZhiPuAiChatOptions.builder()
                .withModel(ZhiPuAiApi.ChatModel.GLM_3_Turbo.getValue())
                .withTemperature(0.4)
                .withMaxTokens(200)
                .build());

ChatResponse response = this.chatModel.call(
    new Prompt("Generate the names of 5 famous pirates."));

// Or with streaming responses
Flux<ChatResponse> streamResponse = this.chatModel.stream(
    new Prompt("Generate the names of 5 famous pirates."));

The ZhiPuAiChatOptions provides the configuration information for the chat requests. The ZhiPuAiChatOptions.Builder is fluent options builder.

Low-level ZhiPuAiApi Client

The ZhiPuAiApi provides is lightweight Java client for ZhiPu AI API.

Here is a simple snippet how to use the api programmatically:

ZhiPuAiApi zhiPuAiApi =
    new ZhiPuAiApi(System.getenv("ZHIPU_AI_API_KEY"));

ChatCompletionMessage chatCompletionMessage =
    new ChatCompletionMessage("Hello world", Role.USER);

// Sync request
ResponseEntity<ChatCompletion> response = this.zhiPuAiApi.chatCompletionEntity(
    new ChatCompletionRequest(List.of(this.chatCompletionMessage), ZhiPuAiApi.ChatModel.GLM_3_Turbo.getValue(), 0.7, false));

// Streaming request
Flux<ChatCompletionChunk> streamResponse = this.zhiPuAiApi.chatCompletionStream(
        new ChatCompletionRequest(List.of(this.chatCompletionMessage), ZhiPuAiApi.ChatModel.GLM_3_Turbo.getValue(), 0.7, true));

Follow the ZhiPuAiApi.java's JavaDoc for further information.
