The speedup ceiling of speculative decoding is constrained by two factors: the drafting cost must be far lower than a single forward pass of the target model, and the acceptance length must be sufficiently long.

UnverifiedIn a two-stage design, using an upper confidence bound on the pilot variance (rather than the point estimate) can significantly reduce the problem of insufficient runs.79% similarVerifiedIn code completion scenarios, using lightweight specialized models with smaller parameter counts but faster inference speed is more reasonable than using large models, because this task has extremely high latency requirements and does not require general reasoning capabilities.78% similarVerifiedAssign the right tasks to the right models — blindly using top-tier models is both slow and quota-consuming.76% similarUnverifiedAs computing costs decline and inference acceleration technologies such as model quantization and speculative decoding become widespread, the generation speed for equivalent quality is expected to be significantly reduced within the next one to two years.76% 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.76% similar
