Not All Prefills Are Equal: PPD Disaggregation for Multi-turn LLM Serving

Zongze Li, Jingyu Liu, Zhen Xu +3

Prefill-Decode (PD) disaggregation has become the standard architecture for modern LLM inference engines, which alleviates the interference of two distinctive workloads. With the g…

Speculative Prefill: Turbocharging TTFT with Lightweight and Training-Free Token Importance Estimation

Jingyu Liu, Beidi Chen, Ce Zhang

Improving time-to-first-token (TTFT) is an essentially important objective in modern large language model (LLM) inference engines. Optimizing TTFT directly results in higher maxima…
