gemma-4-e4b

Gemma is a family of open models built by Google DeepMind. Gemma 4 models are multimodal, handling text and image input (with audio supported on small models) and generating text output.

Gemma 4 introduces key capability and architectural advancements:

• 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.
