VerifiedSpeculative Decoding uses a small, fast draft model to predict multiple tokens in advance, which are then verified in parallel all at once by the large model.82% similarVerified自回归大模型推理瓶颈并非计算量而是内存带宽，推测解码通过拒绝采样保证输出分布与原始大模型完全一致80% similarVerifiedSpeculative decoding is a lossless acceleration technique that does not alter the model's output distribution; it uses a draft model with far fewer parameters than the target model to generate candidate tokens, which the target model then verifies in parallel.80% similarUnverified推测解码在数学上是完全无损的，最终输出与大模型单独生成完全一致，只是速度提升80% 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.78% similar
