Gemma 4 runs offline on 16GB laptops for free

Gemma 4 E4B runs locally on a 16GB laptop with no internet connection. Google's model stores 8 billion total parameters but activates only 4.5 billion at a time, using per-layer embeddings for fast inference. It supports native vision and function calling, enabling offline transcription, document analysis, and tool execution through Obsidian and Ollama.
