A compact, open-weight model from Google's Gemma family, Gemma 4 E4B uses a mixture-of-experts architecture to punch above its active parameter count. It handles text-in, text-out tasks with the efficiency you'd expect from a smaller footprint model. Being Apache 2.0 licensed means it's freely usable and modifiable, making it accessible for local deployment via GGUF or safetensors formats.
