Reasoning – All models in the family are designed as highly capable reasoners, with configurable thinking modes.

Extended Multimodalities – Processes Text, Image with variable aspect ratio and resolution support.

Diverse & Efficient Architectures – Offers Dense and Mixture-of-Experts (MoE) variants of different sizes for scalable deployment.

Optimized for On-Device – Smaller models are specifically designed for efficient local execution on laptops and mobile devices.

Increased Context Window – The small models feature a 128K context window, while the medium models support 256K.

Enhanced Coding & Agentic Capabilities – Achieves notable improvements in coding benchmarks alongside native function-calling support, powering highly capable autonomous agents.

Native System Prompt Support – Gemma 4 introduces native support for the system role, enabling more structured and controllable conversations.
