vLLM: Anatomy of a High-Throughput LLM Inference System
In particular I'll be doing a breakdown of how vLLM [1] works.This post is the first in a series. On its own, it already enables high-throughput inference - but only in an offline setting. I'll emphasize the core ideas rather than exact signatures.

Inside vLLM: Anatomy of a High-Throughput LLM Inference SystemFrom paged attention, continuous batching, prefix caching, specdec, etc. to multi-GPU, multi-node dynamic serving at scaleAugust 29, 2025In this post, I'll gradually introduce all of the core system components and advanced features that make up a modern high-throughput LLM inference system. In particular I'll be doing a breakdown of how vLLM [1] works.This post is the first in a series. It starts broad and then layers in detail (following an inverse-pyramid approach) so you can form an accurate high-level mental model of the complete system without drowning in minutiae.Later posts will dive into specific subsystems.This post is structured into five parts:LLM engine & engine core: fundamentals of vLLM (scheduling, paged…
