Introduction Large Language Models (LLMs) such as GPT‑4, LLaMA, and Claude have moved from research prototypes to production‑grade services that power chatbots, code assistants, and enterprise knowledge bases. In a production environment the inference workload is fundamentally different from training: Low latency is critical – users expect sub‑second responses for interactive use cases. Throughput matters – batch processing of millions of requests per day is common in analytics pipelines. Resource utilization must be maximized – GPUs/TPUs are expensive, and idle hardware directly translates to cost overruns. At the heart of any high‑performance LLM inference service lies a distributed task queue that routes requests from front‑end APIs to back‑end workers that execute the model on specialized hardware. Optimizing that queue is often the single biggest lever for improving latency, throughput, and reliability. ...

As an expert LLM infrastructure engineer, I’ve deployed countless inference systems where time-to-first-token (TTFT) and GPU efficiency make or break production performance. Enter LMCache—a game-changing KV cache layer that delivers 3-10x delay reductions by enabling “prefill-once, reuse-everywhere” semantics across serving engines like vLLM.[1][2] This zero-to-hero tutorial takes you from conceptual understanding to production deployment, covering architecture, integration, pitfalls, and real-world wins. Whether you’re building multi-turn chatbots or RAG pipelines, LMCache will transform your LLM serving stack. ...

Introduction If you’re trying to serve large language models (LLMs) efficiently on GPUs, you quickly run into a wall: GPU memory gets eaten by KV cache Throughput collapses as concurrent users increase You spend more on hardware than on your actual application vLLM is an open-source inference engine designed to fix this. It combines: A highly optimized attention implementation (PagedAttention) Continuous batching and scheduling A production-ready API server (OpenAI-compatible) Tight GPU memory management This tutorial is a concise zero-to-hero guide for developers who want to: ...
