Mastering Llms Fine-Tuning

If you want to build custom LLMs that are faster, cheaper, smarter, and tailored for real business use cases - this is the book that shows you how. The AI landscape is shifting fast. Companies no longer want generic chatbots - they want domain-specific, high-accuracy models fine-tuned for legal, medical, financial, engineering, and enterprise workflows. LLMs Fine-Tuning Mastery gives you everything you need to build these models with confidence. This is the complete, practical handbook for engineers, data scientists, and AI builders who want to go beyond prompting and learn the engineering craft behind fine-tuning cutting-edge models using Python, PyTorch, Hugging Face Transformers, LoRA, QLoRA, and modern RAG pipelines. Whether you're building your first fine-tuned model or deploying a production-scale AI system, this book removes the guesswork and shows you exactly how to do it right. Inside This Book, You Will Learn: ✔ How to Fine-Tune LLMs the Modern WaySFT, instruction tuning, domain adaptation, alignment strategies, and continuous improvement loops. ✔ How to Use LoRA & QLoRA Like a ProSave 60-90% GPU memory while training models that match full fine-tuned performance. ✔ The Secrets of World-Class Dataset EngineeringCleaning, labeling, deduplication, quality scoring, data augmentation, synthetic data generation, and dataset management at scale. ✔ How to Build Production-Ready RAG SystemsImprove grounding, retrieval precision, and model reliability with advanced evaluation and optimization strategies. ✔ Deployment & Scaling Without the PainQuantization, inference optimization, GPU/CPU trade-offs, batching, caching, Triton/FastAPI servers, and observability patterns used in modern AI infra. ✔ End-to-End Architectures Used by Top AI TeamsConcrete workflows for managing experiments, validation, fine-tuning lifecycles, and delivering real value to users.
