Gemma 2
About
Gemma 2 is a series of cutting-edge, lightweight open large language models developed by Google. Leveraging the same foundational research as the Gemini models, Gemma 2 offers models with 2 billion, 9 billion, and 27 billion parameters. These decoder-only text-to-text models, primarily trained on English data, demonstrate strong capabilities in multilingual tasks. They come in both pre-trained and instruction-tuned versions, making them versatile for diverse text generation applications such as question answering, summarization, and reasoning. Smaller models are optimized for deployment on resource-limited devices, while the larger variants deliver competitive performance with efficiency innovations like alternating local and global attention, logit soft-capping, and grouped-query attention12. Additionally, Gemma 2 includes tools for facilitating responsible AI development3.
