VerifiedWhen the draft model prediction accuracy of Speculative Decoding reaches 60–80%, the overall inference speed can be improved by 2–3 times.73% similarUnverifiedThe practical value of the speedup depends on the proportion of the target operation within the overall computation.71% similarUnverifiedResearch shows that high-quality prompts can bring a 20%–40% improvement in task completion rates compared to casually written prompts under the same model conditions.71% similarUnverifiedWord error rate measures the proportion of edit distance between a model's output and the ground-truth transcription, and is the most core accuracy metric.70% similarUnverified推测解码中当草稿通过率低于50%时，实际加速效果会大打折扣甚至产生负优化70% similar
