Efficient LLM Inference: Infrastructure and Serving Optimization

Deploying large language models in production requires more than just loading a model; it demands highly optimized infrastructure to manage massive memory and compute constraints. Without the right setup, serving costs can skyrocket while user experience suffers from high latency. This text-based course guides you through the foundational concepts and advanced strategies of LLM serving, helping you configure infrastructure that minimizes latency and maximizes throughput. You will learn how to design systems that handle high-concurrency demands without wasting expensive hardware resources. What you'll learn: - Understand key bottlenecks in LLM generation, including memory bandwidth and compute limitations. - Implement KV caching and advanced memory management techniques like PagedAttention to optimize memory use. - Configure continuous batching to handle multiple concurrent user requests efficiently. - Apply speculative decoding to accelerate token generation speeds. - Explore model quantization methods to reduce memory footprint without losing accuracy. - Analyze hardware utilization metrics to continuously tune your serving infrastructure. You will start with core concepts of autoregressive generation and memory bottlenecks before exploring configuration strategies and optimization algorithms through detailed written explanations and configuration examples. This progressive structure ensures you build a solid theoretical foundation before moving to practical deployment configurations. This course is designed for software engineers, system architects, and AI developers transitioning into machine learning operations. No advanced hardware background is required, though basic familiarity with Python and command-line interfaces is helpful.
