Model Introduction
Gemma 4 26B A4B is an instruction-tuned multimodal Mixture-of-Experts (MoE) model developed by Google DeepMind. It supports text and image inputs and generates text output, making it suitable for text generation, reasoning, coding, visual understanding, and multimodal tasks. The model contains approximately 25.2B parameters while activating approximately 3.8B parameters during inference.
