Google DeepMind released Gemma4, its most powerful open-source model with ~30B parameters but significantly higher intelligence density, matching top closed-source models from 1.5 years ago. Its new E2B architecture reduces GPU memory usage to just 2GB by offloading parameters to CPU/disk, enabling deployment on edge devices. Gemma4 integrates with Android Studio for offline code generation without cloud reliance, supports 140 languages and multimodal tasks, and predicts smartphones will run models equivalent to Gemini3Pro within 1-2 years.
