Judge Decoding: Faster Speculative Sampling Requires Going Beyond Model Alignment

Gregor Bachmann, Sotiris Anagnostidis, Albert Pumarola +6

The performance of large language models (LLMs) is closely linked to their underlying size, leading to ever-growing networks and hence slower inference. Speculative decoding has be…
