VertexAI-KT is a Kotlin multiplatform library designed to simplify the integration with the Vertex AI PaLM API, a powerful service provided by Google Cloud for creating and training generative models. This library provides an abstraction layer on top of the VertexAI API, enabling seamless integration with Android and iOS platforms.

• Simplified Integration: VertexAI-KT simplifies the process of integrating your Kotlin-based mobile applications with the Vertex AI PaLM API;
• Cross-Platform Support: The library supports both Android and iOS platforms, allowing you to leverage the power of Vertex AI PaLM in your mobile apps;
• Abstraction Layer: VertexAI-KT creates an abstraction layer on top of the VertexAI API, providing an intuitive and easy-to-use interface for creating and training generative models.

To get started with the SDK, you'll need the following information for initialization:

• Project ID: The Project ID refers to your Google Cloud Project ID.
• Access Token: You'll need an access token for authentication. For more details, please refer to the Google Cloud Platform Authentication documentation.

It's important to have these details ready before proceeding with the SDK setup.

Add the following line to import the library via Gradle. First, make sure Maven Central has been added:

repositories {
    mavenCentral()
    // ...
}

Then, simply import the dependency to your build.gradle dependencies:

implementation("com.hexascribe:vertexai-kt-jvm:LATEST-VERSION")

Take a look at the Java code snippet below for an example of how to initialize and use one of the supported features:

VertexAI vertexAI = new VertexAI.Builder()
        .setAccessToken("YOUR_ACCESS_TOKEN")
        .setProjectId("YOUR_GOOGLE_CLOUD_PROJECT_ID")
        .build();
TextRequest textRequest = vertexAI.textRequest()
        .setModel("some-model")
        .setTemperature(0.8)
        .setMaxTokens(256)
        .setTopK(40)
        .setTopP(0.8);
textRequest.execute("Say this is a test", new VertexAI.Callback<String>() {
    @Override
    public void onSuccess(@NotNull String result) {
        // handle success
    }

    @Override
    public void onError(@NotNull Throwable throwable) {
        // handle error
    }
});

Take a look at the Kotlin code snippet below for an example of how to initialize and use one of the supported features:

val vertexAI by lazy {
    VertexAI.Builder()
        .setAccessToken("YOUR_ACCESS_TOKEN")
        .setProjectId("YOUR_GOOGLE_CLOUD_PROJECT_ID")
        .build()
}
val textRequest by lazy {
    vertexAI.textRequest()
        .setModel("some-model")
        .setTemperature(0.8)
        .setMaxTokens(256)
        .setTopK(40)
        .setTopP(0.8)
}
viewModelScope.launch {
    val result = textRequest.execute("Say this is a test")
    print(result.getOrThrow())
}

To use this library in your iOS project, follow these steps:

1. Go to your project’s file settings and click "Add Package".
2. In the search bar at the top right, enter https://github.com/hexascribe/vertexai-kt.git
3. Once you have found the package, click the "Add Package" button.

You can now start using the VertexAI-KT in your iOS project!

Take a look at the Swift code snippet below for an example of how to initialize and use one of the supported features:

var vertexAI: VertexAI {
    VertexAI.Builder()
        .setAccessToken(accessToken: "YOUR_ACCESS_TOKEN")
        .setProjectId(projectId: "YOUR_GOOGLE_CLOUD_PROJECT_ID")
        .build()
}
var textRequest: TextRequest {
    vertexAI.textRequest()
        .setModel(model: "some-model")
        .setTemperature(temperature: 0.2)
        .setMaxTokens(maxTokens: 256)
        .setTopK(topK: 40)
        .setTopP(topP: 0.8)
}
Task.init {
    let result = try await textRequest.execute(prompt: "Say this is a test")
    print(result.getOrThrow())
}
