What papers say

Verbatim critique sentences, each from a paper that cites ParallelSpec as a baseline.

“Once alternatives from different depths are combined into a draft tree, they form a large combinatorial space in which many paths are not coherent continuations, and the verifier wastes budget on them.”
— SpecBlock: Block-Iterative Speculative Decoding with Dynamic Tree Drafting
“these approaches still use target model information, making them inherently target-dependent”
— PARD: Accelerating LLM Inference with Low-Cost PARallel Draft Model Adaptation
“ParallelSpec~xiao2024parallelspec proposed parallel drafting with a single transformer layer, but omits critical implementation details---notably whether and how target model hidden states are utilized---and does not address the memory scaling challenges that arise from extended training sequences with multiple parallel prediction positions.”
