The core idea of speculative decoding is: use a smaller draft model to quickly generate multiple candidate tokens, then have the target large model verify in parallel in one pass whether these tokens are acceptable.

UnverifiedSpeculative decoding uses a lightweight draft model to generate candidate tokens that are then verified in parallel by a large model; it is a strictly lossless acceleration method that typically delivers a 2–3× speedup.78% similarVerifiedSpeculative decoding submits the candidate sequence generated by the draft model to the target model as a whole for one-shot batch verification, requiring only a single forward pass to determine whether each candidate token is correct.76% similarUnverifiedTesting the model separately before writing the agent code can confirm whether the underlying model's grounding capability meets the standard and measure the token usage of a single call, providing a baseline for quota planning and cost budgeting.74% similarUnverifiedFor speculative decoding, the model's official companion drafter should be preferred; if none exists, choose a third-party one but must measure the acceptance rate; the speculative token count should be tried starting from 2 to 4.73% 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.71% similar
