VerifiedGrouped Query Attention (GQA) and Multi-Query Attention (MQA) reduce KV cache memory usage during inference by having multiple query heads share the same group of key/value heads, and are standard optimizations in models such as Llama 3 and Mistral.72% similarUnverifiedGQA reduces the size of the KV Cache by having multiple Query heads share the same set of Key-Value heads.66% similarUnverifiedGQA (Grouped-Query Attention) and MQA (Multi-Query Attention) were the industry's solutions prior to MLA for alleviating the KV cache problem by sharing Key/Value heads.63% similarUnverified自注意力通过将输入序列映射为查询Q、键K、值V三组向量，计算Q与K的点积相似度后经Softmax归一化得到注意力权重，再加权汇聚V向量62% similarUnverifiedMQA令所有查询头共享同一组Key-Value以压缩KV Cache62% similar
