Overview
Google DeepMind's Gemma 4 models are a family of open, multimodal models designed for diverse applications. The Gemma 4 31B-it is a 30.7 billion parameter instruction-tuned variant, capable of processing text, image, and video inputs to generate text. It features a substantial 256K token context window and supports over 140 languages.
Key Capabilities
- Multimodal Understanding: Processes text, images (with variable aspect ratio and resolution), and video inputs. The E2B and E4B variants also natively support audio.
- Reasoning: Designed with highly capable reasoning abilities, including configurable thinking modes for step-by-step processing.
- Extended Context: Supports long contexts, with the 31B model featuring a 256K token window.
- Enhanced Coding & Agentic Capabilities: Shows significant improvements in coding benchmarks and includes native function-calling support for autonomous agents.
- Native System Prompt Support: Introduces native support for the
system role, enabling more structured and controllable conversations. - Hybrid Attention Mechanism: Employs a hybrid attention mechanism combining local sliding window attention with global attention for efficient long-context processing.
