Speculative decoding's rejection-sampling-based verification algorithm ensures that the output distribution is exactly equivalent to—rather than merely an approximation of—running the main model alone.

UnverifiedTraditional speculative decoding uses strict rejection-sampling-based verification rules, where a draft token is only accepted when it exactly matches the target model's sampled result.75% similarUnverifiedSpeculative decoding is a lossless acceleration technique whose output is mathematically fully equivalent to that of the original target model, because all tokens have been verified by the large model.72% similarUnverifiedThe output quality of a model is probabilistic and can only be fully exposed under real traffic distribution, whereas the correctness of code services can be verified in advance through unit tests or integration tests.72% similarUnverifiedThe essence of speculative decoding is to predict multiple tokens at low cost and then have the main model verify them in batch; the higher the hit rate, the more valid tokens produced per verification step.72% similarUnverifiedThe evaluation used only one prompt, ran each model only once, used greedy decoding, scored answers based on normalized exact match, and did not score evidence_ids.71% similar
