Speculative decoding uses a small model to propose several tokens, then asks the larger target model to verify them in one pass.
Fixed-cost drafter speeds speculative decoding as context lengths grow
LongSpark proposes token blocks from bounded multiscale context views, avoiding drafting costs that increase with the confirmed prefix.

He and colleagues introduce LongSpark, a speculative-decoding drafter whose per-round computation and context state remain constant with respect to prefix length.
Why this paper
Independent
In one line
LongSpark decouples drafter cost from prefix length by extracting fixed-size, multiscale views from target verification.
