Speculative decoding typically achieves 1.5–3x speedup depending on the draft hit rate; if rejections are frequent, the extra overhead may offset the gains.

VerifiedSpeculative decoding typically delivers a 2–3× speedup in practical applications.77% similarUnverifiedSpeculative decoding can achieve several-fold improvements in inference throughput when the draft acceptance rate is high.75% similarVerifiedA higher acceptance rate means the draft model's guesses are more accurate and the large model needs to redo less work, which directly determines the actual speedup achieved by speculative decoding.72% similarUnverifiedThe higher the review tier, the longer developers wait for feedback, and the impact of this delay on iteration cadence is often more direct than the token cost.71% similar
