DistillSpec: Improving Speculative Decoding via Knowledge Distillation

Yongchao Zhou, Kaifeng Lyu, Ankit Singh Rawat +5

Speculative decoding (SD) accelerates large language model inference by employing a faster draft model for generating multiple tokens, which are then verified in parallel by the la…
