Google Generative AI SDK for Kotlin Multiplatform ✨

The Google Generative AI client SDK for Kotlin Multiplatform enables developers to use Google's state-of-the-art generative AI models (like Gemini) to build AI-powered features and applications. This SDK supports use cases like:

• Generate text from text-only input
• Generate text from text-and-images input (multimodal)
• Build multi-turn conversations (chat)

For example, with just a few lines of code, you can access Gemini's multimodal capabilities to generate text from text-and-image input:

val generativeModel = GenerativeModel(
    modelName = "gemini-1.5-pro-vision-latest",
    apiKey = "YOUR_API_KEY"
)

val cookieImageData: ByteArray = // ...
val inputContent = content {
  image(PlatformImage(cookieImageData))
  text("Does this look store-bought or homemade?")
}

val response = generativeModel.generateContent(inputContent)
print(response.text)

Supports the following Kotlin Multiplatform targets:

• Android
• iOS
• JVM
• JS
• Wasm (Use this version)

Installation and usage

Add the following dependency to your Kotlin Multiplatform project for commonMain:

commonMain.dependencies {
    implementation("dev.shreyaspatil.generativeai:generativeai-google:<version>")
}

Check for latest version in the releases.

For detailed instructions, you can find a quickstart for the Google AI client SDK for Android (Since this is a Fork of the original project by Google).

This quickstart describes how to add your API key and the SDK's dependency to your app, initialize the model, and then call the API to access the model. It also describes some additional use cases and features, like streaming, counting tokens, and controlling responses.

Releases

The versioning scheme is of the form X-Y where:

X is the Generative AI Android SDK version that is being tracked. Y is the Multiplatform SDK version. For example, if Generative AI Android SDK is on 0.9.0 and Multiplatform SDK is on 1.0.1, the artifact for a release will be dev.shreyaspatil.generativeai:generativeai-google:0.9.0-1.0.1.

Try sample app

Try these apps built with this SDK by the community:

• PatilShreyas/ChaKt: Chat-prompt based app for Android, iOS, Desktop, Web. Powered by this multiplatform SDK.
• joreilly/GeminiKMP: Kotlin Multiplatform sample that uses Gemini Generative AI APIs. Runs on Android, iOS, Desktop, WearOS and Wasm-based Compose for Web.

(Have you built anything on top of this SDK? Let's add it here)

Documentation

You can use the APIs mentioned in the API Reference by the official library.

See the Gemini API Cookbook or ai.google.dev for complete documentation.

From the official library, there are two major changes:

• Package com.google is mapped to dev.shreyaspatil.
• Image(Bitmap) was there for Android, instead PlatformImage(ByteArray) is used for KMP.
