Gemma 4: Byte for byte, the most capable open models

Google DeepMind has released Gemma 4, a family of open-source AI models available in four sizes (2B to 31B parameters, where parameters are the trainable weights in a neural network) designed for complex reasoning and agentic workflows (AI systems that can autonomously plan and use tools to complete tasks). The models are optimized to run efficiently on various hardware from mobile phones to workstations and support advanced features like multimodal processing (handling text, images, video, and audio), function-calling for tool integration, and context windows up to 256K tokens (units of text the model can process in one response).
