Is Speculative Decoding Worth It? Profiling vLLM on NVIDIA Blackwell — Akamai

A small model guesses the next few tokens. The big model checks them in one pass. When is that worth it? Sheilah Kirui, developer advocate at Akamai, explains speculative decoding and how to tell whether it's worth turning on. She walks through the prefill and decode phases of inference, how a small draft model proposes tokens that the target model verifies in a single forward pass, and the memory cost of hosting a second model and its KV cache.
