At Google, we’re committed to bringing the most capable AI models directly to the Android devices in your pocket. Today, we’re thrilled to announce the release of our latest state-of-the-art open model: Gemma 4.
These models are the foundation for the next generation of Gemini Nano, so code you write today for Gemma 4 will automatically work on Gemini Nano 4-enabled devices that will be available later this year. With Gemini Nano 4, you’ll benefit from our additional performance optimizations so you can ship to production across the Android ecosystem with the most efficient on-device inference.
You can get early access to this model today through the AICore Developer Preview.
Because Gemma 4 natively supports over 140 languages, you can expect improved localized, multilingual experiences for your global audience. Furthermore, Gemma 4 offers industry-leading performance with multimodal understanding, allowing your apps to understand and process text, images, and audio. To give you the best balance of performance and efficiency, Gemma 4 on Android comes in two sizes:
The new model is up to 4x faster than previous versions and uses up to 60% less battery. Starting today, you can experiment with improved capabilities including:
Join the Developer Preview today to download these models in preview models and start building next-generation features right away.
You can try out the model without code by following the Developer Preview guide. If you want to jump straight into integrating these models with your existing workflow, we’ve made that seamless. Head over to Android Studio to refine your prompt and build with the familiar ML Kit Prompt API. We’ve introduced a new ability to specify a model, allowing you to target the E2B (fast) or E4B (full) variants for testing.
// Define the configuration with a specific track and preference val previewFullConfig = generationConfig { modelConfig = ModelConfig { releaseTrack = ModelReleaseTrack.PREVIEW preference = ModelPreference.FULL } } // Initialize the GenerativeModel with the configuration val previewModel = GenerativeModel.getClient(previewFullConfig) // Verify that the specific preview model is available val previewModelStatus = previewModel.checkStatus() if (previewModelStatus == FeatureStatus.AVAILABLE) { // Proceed with inference val response = previewModel.generateContent("If I get 26 paychecks per year, how much I should contribute each paycheck to reach my savings goal of $10k over the course of a year? Return only the amount.") } else { // Handle the case where the preview model is not available // (e.g., print out log statements) }
The goal of this Developer Preview is to give you a head start on refining prompt accuracy and exploring new use cases for your specific apps.
We will be making several updates throughout the preview period, including support for tool calling, structured output, system prompts, and thinking mode in Prompt API, making it easier to take full advantage of the new capabilities and significant performance optimizations in Gemma 4.
The preview models are available for testing on AICore-enabled devices. These models will run on the latest generation of specialized AI accelerators from Google, MediaTek, and Qualcomm Technologies. On other devices, the models will initially run on a CPU implementation that is not representative of final production performance. If your device is not AICore-enabled, you can also test these models via the AI Edge Gallery app. We’ll provide support for more devices in the future.
