Google announced Gemma 4 as the base for next-gen Gemini Nano 4, available via Android AICore Developer Preview. The on-device model is 4x faster and uses 60% less battery than the previous version. Android Studio now supports Gemma 4 as a local agentic coding assistant. The AICore preview will add tool calling, structured output, system prompts, and thinking mode. Developers can also use Google AI Edge for cross-platform edge deployment.
