Qwen3.6-27B speculative decoding gets better on heavier quants
I finished the speed leg of my spec-decode benchmarking for Qwen3.6-27B, main algorithms across quants. Overall: the heavier the quant, the more spec-decode buys you (10 of 10 speculative configs rank Q8 > Q6 > Q4 by multiplier). Acceptance is quant-independent at matched depth, the base step slows with weight bytes, d
