Models using GQA (grouped-query attention) or MLA (multi-head latent attention) can significantly compress the KV Cache, which is the key architectural prerequisite for running long contexts on small VRAM.

VerifiedMulti-Head Latent Attention (MLA) significantly reduces KV Cache memory usage during the inference phase by performing low-rank compression on the Key-Value cache.78% similarUnverifiedKV cache optimization has four main technical approaches: quantization, sparse attention, low-rank approximation, and multi-query/grouped-query attention (MQA/GQA).72% similarUnverifiedGQA can reduce KV Cache memory during inference to 1/4 of MHA while retaining stronger modeling capability than MQA72% similarUnverifiedThe performance bottleneck in large model inference is often concentrated in attention computation and KV Cache management.71% similarUnverifiedModern large models (such as Qwen, Llama 3, Mistral, etc.) generally use grouped query attention (GQA), and the number of KV heads is usually far smaller than the number of query heads.71% similar
