Grouped-query attention assigns several query heads to each shared key-value head. It stores fewer distinct key and value streams than full multi-head attention while retaining multiple query heads.
Fewer key-value heads shrink cache footprint and bandwidth requirements during generation. The model architecture chooses the sharing ratio, so serving software must follow the checkpoint design.
Attention kernels map each query-head group to its corresponding key-value head. Operators verify kernel support, cache layout, and quality for the model they deploy.
