GQA and MQA save the most in long-context, large-batch, high-concurrency inference scenarios, but the compression benefit weakens in short-sequence or small-batch scenarios, and they carry the risk of reduced expressiveness.

UnverifiedModels 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.76% similarUnverifiedGQA can reduce KV Cache memory during inference to 1/4 of MHA while retaining stronger modeling capability than MQA72% similarVerifiedModern quantization schemes such as GPTQ, AWQ, and the grouped quantization of the GGUF format can reduce model size by more than 75% while retaining the vast majority of reasoning capability through layer-by-layer calibration and outlier protection.70% similarUnverifiedThe lower the quantization bit-width, the greater the precision loss; mainstream industry solutions include GPTQ, AWQ, and GGUF.70% similarUnverifiedQAT simultaneously optimizes for low loss and flat curvature around the low-loss point, keeping the quantization error within a controllable range.70% similar
