Gemma 4 E4B is a dense model with 8B parameters. Google describes it as having 4.5B effective parameters. Google DeepMind lists a context window of 128K tokens. The model accepts text, image and audio input. The weights are released under Apache 2.0, which allows commercial use. The official weights on Hugging Face take about 16.0 GB in BF16. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
