UnverifiedGPTQ and AWQ are the mainstream directions for post-training quantization, capable of compressing models to 4-bit precision with almost no loss in perplexity.76% similarUnverifiedGPTQ is a post-training quantization scheme based on layer-wise Hessian matrices, AWQ is activation-aware weight quantization, and modern quantization schemes can control perplexity loss to within 1–2%.73% similarUnverifiedThe idea of mixed-precision routing is consistent with the evolution of GPTQ and AWQ frameworks in the LLM quantization domain—namely, that understanding the activation distribution of each layer and dynamically allocating precision budgets is key to making low-bit quantization usable.73% similarUnverified选择性量化思路与LLM领域的GPTQ、AWQ等量化方法一脉相承71% similarUnverifiedSpeculative decoding technology, in which a local small model drafts answers and a large model verifies them, can improve overall throughput speed by 2 to 4 times without degrading quality.70% similar
