Gemma 4 E2B is a dense model with 5.1B parameters. Google describes it as having 2.3B 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 10.2 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.
