Google releases Gemma 2 with efficient architecture, outperforming larger models

Google has released Gemma 2, featuring new 9B and 27B parameter models that prioritize architectural efficiency over sheer size. These models utilize a redesigned transformer architecture with a hybrid attention mechanism and Grouped-Query Attention, reducing computational and memory costs. This efficiency allows the 27B model to run on a single NVIDIA H100 or Google TPU, making it competitive with larger models and lowering deployment expenses for developers. AI

IMPACT Enables more powerful and efficient open-source AI applications by reducing inference costs and hardware requirements.

    Gemma 2 is here. It's not the size, it's the architecture.

    <p>Google has released Gemma 2, the next version of its open model family, and the takeaway for builders is simple: architectural efficiency is the new parameter count. The new 9B and 27B models deliver performance that is competitive with models more than twice their size, makin…
