Gemma 2's Architecture: More Performance from Less Model (opens in new tab)

Google's new Gemma 2 models are a strong signal for where open-source AI is heading. The 27B parameter model delivers performance competitive with models more than twice its size, and the smaller variants punch well above their weight class. This isn't just about a larger training dataset; it’s the result of specific, practical architectural changes that prioritize efficiency. a hybrid attention mechanism The core of any transformer is the attention mechanism, but standard self-attention has ...
