In the verification stage, ProVe-lossless scores each token in the proposal block in parallel and accepts only the prefix consistent with the proposer's own AR predictions, thereby guaranteeing that the output sequence is identical to token-by-token greedy decoding.

UnverifiedThe parallel verification mechanism of speculative decoding guarantees that the final output sequence distribution is exactly identical to sampling token by token from the target model alone, so it is lossless acceleration.76% similarUnverifiedThe 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.75% similarUnverifiedProVe-lossless uses the proposer itself as the verifier, exactly reproducing the proposer's greedy AR decoding results and achieving lossless acceleration.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 4.71% similarUnverifiedTraditional 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.71% similar
