What does research say about: Speculative decoding accelerates inference without quality loss?

Draft-then-verify speculative decoding achieves 2-3x faster token generation with identical output quality, reducing GPU-hour costs proportionally. (Source: Leviathan et al., 'Fast Inference from Transformers via Speculative Decoding', Google Research, 2023). Without speculative decoding, autoregressive generation is bottlenecked by sequential token production, wasting GPU capacity.
