UnverifiedSpeculative decoding typically achieves 1.5–3x speedup depending on the draft hit rate; if rejections are frequent, the extra overhead may offset the gains.77% similarVerifiedWhen compression techniques such as quantization, knowledge distillation, and operator fusion are used in combination, inference speed typically improves by 2–4×.76% similarUnverifiedThe upper speedup limit of the decoding stage (approximately 2.7×) is higher than the upper speedup limit of the encoding stage.76% similarUnverifiedSpeculative decoding improves generation speed without changing output quality.74% similarUnverifiedGeneration speed can be multiplied by increasing the number of agents or token consumption, but manual review speed is essentially fixed, making review the new bottleneck.74% similar
