UnverifiedDistilBERT 通过知识蒸馏将 BERT 参数压缩至 66M，推理速度提升 60% 而性能损失约 3%67% similarUnverifiedTransformer模型中首尾几层对量化更敏感，中间层冗余度更高，注意力层和前馈网络层对量化的容忍度不同65% similarUnverified研究表明(Dettmers et al., 2022)，Transformer模型中特定隐藏维度会在所有token和层中持续出现异常大激活值，模型超过6.7B参数时现象更显著64% similarUnverified扩散模型生成质量高、细节丰富但推理速度较慢,Transformer架构速度快但在细节精度和真实感上往往不如扩散模型63% similarUnverified在神经网络推理中Softmax、LayerNorm等对数值范围敏感的操作极易因FP16有限的指数位引发上溢或下溢，误差在Transformer多层堆叠中累积放大63% similar
