Gemma 2: An Overview

Gemma 2, Google's latest contribution to its Gemma family, prioritizes top-tier performance and efficiency. Building upon the success of its predecessors, Gemma 2 boasts substantial improvements in both architecture and capabilities. The two available versions include a 27-billion parameter model that requires less than half the processing power of models like Llama 3 70B while maintaining comparable performance. This efficiency translates to lower deployment costs and broadens access to high-performance AI. A smaller 9-billion parameter model also exists, exceeding the capabilities of Llama 3 8B.

Key Gemma 2 Features:

• Superior Performance: The model excels in a wide range of tasks, from basic question answering and common-sense reasoning to more complex challenges in mathematics, science, and programming.
• Efficiency and Accessibility: Gemma 2 is engineered for efficient execution on NVIDIA GPUs or a single TPU host, significantly simplifying deployment.
• Open-Source Accessibility: Similar to its predecessors, Gemma 2's weights and architecture are publicly available, enabling developers to build upon it for both personal and commercial projects.

Gemma 2 Benchmarks

Gemma 2 demonstrates significant improvements over its predecessor. Both the 9-billion and 27-billion parameter versions achieve impressive results across various benchmarks.

The 27-billion parameter Gemma 2 model rivals larger models like LLaMA 70B and Grok-1 314B, while consuming considerably less computational resources, as shown in the image above. Gemma 2 surpasses the Grok model in mathematical capabilities, as evidenced by its GSM8k scores. It also demonstrates strong performance on multilingual understanding tasks (MMLU benchmark), achieving scores comparable to the Llama 3 70B model despite its smaller size. Both the 9-billion and 27-billion parameter versions consistently achieve high scores across diverse benchmarks, including human evaluations, mathematical, scientific, and logical reasoning tasks.
