QianFan Image Generation

Spring AI supports CogView, the Image generation model from QianFan.

Prerequisites

You will need to create an API with QianFan to access QianFan language models.

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

export SPRING_AI_QIANFAN_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 QianFan 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-qianfan-spring-boot-starter</artifactId>
</dependency>

or to your Gradle build.gradle build file.

dependencies {
    implementation 'org.springframework.ai:spring-ai-qianfan-spring-boot-starter'
}

Refer to the Dependency Management section to add the Spring AI BOM to your build file.

Runtime Options

The QianFanImageOptions.java provides model configurations, such as the model to use, the quality, the size, etc.

On start-up, the default options can be configured with the QianFanImageModel(QianFanImageApi qianFanImageApi) constructor and the withDefaultOptions(QianFanImageOptions defaultOptions) method. Alternatively, use the spring.ai.qianfan.image.options.* properties described previously.

At runtime you can override the default options by adding new, request specific, options to the ImagePrompt call. For example to override the QianFan specific options such as quality and the number of images to create, use the following code example:

ImageResponse response = qianFanImageModel.call(
        new ImagePrompt("A light cream colored mini golden doodle",
        QianFanImageOptions.builder()
                .withN(4)
                .withHeight(1024)
                .withWidth(1024).build())

);

In addition to the model specific QianFanImageOptions you can use a portable ImageOptions instance, created with the ImageOptionsBuilder#builder().
