Large Language Models
Fast LLM Serving with vLLM and PagedAttention
September 19, 2:30 PM - 3:00 PMLLMs promise to fundamentally change how we use AI across all industries. However, actually serving these models is challenging and can be surprisingly slow even on expensive hardware. To address this problem, we are developing vLLM, an open-source library for fast LLM inference and serving. vLLM utilizes PagedAttention, our new attention algorithm that effectively manages attention keys and values. vLLM equipped with PagedAttention achieves up to 24x higher throughput than HuggingFace Transformers, without requiring any model architecture changes. vLLM has been developed at UC Berkeley and deployed for Chatbot Arena and Vicuna Demo for the past three months. In this talk, we will discuss the motivation, features, and implementation of vLLM in depth, and present our future plan.
