Google Announces Gemma 4 in AICore Developer Preview with Enhanced Multimodal Capabilities
Key Takeaways
- ▸Gemma 4 achieves 4x faster performance and 60% battery savings, enabling efficient on-device AI on Android devices
- ▸Dual model variants (E2B for speed, E4B for reasoning) allow developers to optimize for their specific use cases
- ▸Native support for 140+ languages and multimodal AI (text, image, audio) enables localized, globally-accessible applications
Summary
Google has announced Gemma 4, its latest open-source AI model, now available in the AICore Developer Preview for Android developers. The model marks a significant advancement in on-device AI capabilities, offering up to 4x faster performance and 60% less battery consumption compared to previous versions. Gemma 4 comes in two variants—E4B for higher reasoning power and E2B for maximum speed (3x faster)—and natively supports over 140 languages with multimodal understanding of text, images, and audio.
The model introduces several improved capabilities including enhanced reasoning with chain-of-thought logic, better mathematical problem-solving, improved time understanding for calendar and reminder applications, and more accurate image understanding for OCR tasks. Google emphasizes that code written today for Gemma 4 will automatically work on the forthcoming Gemini Nano 4-enabled devices launching later in 2026, providing developers with continuity and forward compatibility. Developers can access the preview through AICore and begin building next-generation features using familiar tools like Android Studio and the ML Kit Prompt API.

Editorial Opinion
Gemma 4 represents a meaningful step toward practical on-device AI, addressing the critical tradeoff between capability and efficiency that has constrained mobile AI adoption. The dual-variant approach and substantial performance gains make this particularly valuable for developers targeting resource-constrained devices. However, the success of this ecosystem will ultimately depend on whether Pixel TPU hardware and broader Android device adoption can match the capabilities Google is promising—early developer traction will be essential to validate the platform.
