New Grouped Value Attention method slashes Transformer KV cache size

Researchers have introduced Grouped Value Attention (GVA), a novel method to reduce the memory footprint of KV caches in Transformer models. GVA achieves this by storing grouped values and reconstructing content keys using a learned linear map, which can be absorbed into the query during inference. This approach demonstrates a significant reduction in persistent cache scalars, approximately 45-47% compared to Grouped Query Attention (GQA), while maintaining near-GQA benchmark accuracy. The team is developing custom decoding kernels to further enhance inference speed and plans an open-source release. AI

IMPACT This research could lead to more efficient LLM inference, enabling faster processing and reduced hardware requirements.
