In a text generation acceleration technique, a small, fast 'draft' model proposes a sequence of candidate tokens (e.g., 5 tokens). A larger, more accurate 'target' model then takes this entire 5-token sequence and computes the correct probability distribution for each of the 5 positions simultaneously in a single forward pass. What is the primary advantage of this parallel evaluation by the target model compared to a standard approach where the large model generates tokens one by one?

Determining the Maximum Number of Consecutively Accepted Tokens in Speculative Decoding
In a text generation acceleration technique, a small, fast 'draft' model proposes a sequence of candidate tokens (e.g., 5 tokens). A larger, more accurate 'target' model then takes this entire 5-token sequence and computes the correct probability distribution for each of the 5 positions simultaneously in a single forward pass. What is the primary advantage of this parallel evaluation by the target model compared to a standard approach where the large model generates tokens one by one?

Diagram of the Acceptance/Rejection Outcome from an Evaluation Model
In a text generation acceleration technique where a draft model proposes a sequence of tokens, the larger verification model, during its single parallel evaluation pass, directly outputs a final 'accept' or 'reject' decision for each token, bypassing the need to compute its own probability distribution for those token positions.
