Speculative Decoding: The Art of Guessing Well

Large Language Models spend most of their decoding time not computing, but waiting: every new token requires reading all of the model weights from memory, only to multiply them by a single vector. What if the model could check several tokens for the price of one? In this post we’ll derive speculative decoding from first principles, build a general framework that covers every modern drafte...
