Small Language Models in Action. Efficient generative AI for resource-constrained systems (English Edition) (en Inglés) - Dr. Sireesha Muppala;Randy DeFauw;Shelbee Eigenbrode

While large language models have transformed generative AI (GenAI), their heavy compute demands, high inference costs, and cloud dependency make them impractical for many real-world applications. Small language models (SLMs) offer a compelling alternative, delivering powerful GenAI capabilities while running efficiently on mobile devices, edge hardware, and cost-constrained systems. This book bridges the gap between theoretical model architecture and real-world deployment, serving as your ultimate engineering roadmap for building efficient, compact, and production-ready AI systems. 

This book systematically guides you through the entire life cycle of small language models across 14 comprehensive chapters. This book begins with the foundations of SLMs, covering their architecture, design principles, and size-performance trade-offs. Readers will master core compression techniques including knowledge distillation, quantization, and pruning to shrink models while preserving accuracy. The book also explores lightweight transformers, efficient fine-tuning, and inference optimization for latency and memory, followed by practical deployment on edge and mobile platforms using ONNX and TensorFlow Lite. Finally, the book explores SLM-powered agents capable of tool use and multi-step reasoning, hybrid architectures that combine small and large models, and real-world case studies, closing with benchmarking and cost-performance frameworks.
