PosS: Position Specialist for Speculative Decoding

This repository provides the model checkpoint for PosS (Position Specialist), a speculative decoding method proposed in the paper:

PosS: Position Specialist Generates Better Draft for Speculative Decoding

PosS improves speculative decoding by training a position-specialized draft model that generates higher-quality drafts, leading to improved efficiency and acceptance rates during decoding.
