Leviathan and Chen teams: distribution-preserving speculative decoding

Contribution grade

Language-model inference algorithms · Human-designed research method or resource

Reference score185,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Used a faster draft model and parallel target-model scoring with corrected acceptance sampling to produce multiple tokens per target call while preserving its sampling distribution.

Scientific scope

Used a faster draft model and parallel target-model scoring with corrected acceptance sampling to produce multiple tokens per target call while preserving its sampling distribution. Two independently developed papers share the core sampler and are counted once. The nine authors belong to two distinct bylines. Gains depend on acceptance, hardware and workloads; floating-point numerics still matter.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
