LLM Systems Engineering for AI Engineers: Build, Fine-Tune, Evaluate, Deploy, and Monitor Production-Ready Large Language Models with Python, PyTorch, Hugging Face, RAG, and MLOps

Move beyond LLM demos and learn how production AI systems are actually engineered.

Many AI projects start with a promising prompt, then struggle when real users, private data, latency limits, evaluation failures, security risks, and deployment problems appear. How do you choose between RAG, fine-tuning, continued pretraining, hosted APIs, and open models? How do you test whether an LLM system is accurate, safe, cost-aware, and ready for production?

Solution

LLM Systems Engineering for AI Engineers gives you a practical engineering path for building large language model applications from prototype to production using Python, PyTorch, Hugging Face, RAG, FastAPI, vector databases, evaluation workflows, deployment practices, monitoring, and MLOps.

You will learn how to:

Set up a clean LLM engineering workspace
Understand tokens, transformers, sampling, and inference behavior
Prepare datasets for training, fine-tuning, RAG, and evaluation
Train a small language model from scratch with PyTorch
Use Hugging Face, PEFT, LoRA, and QLoRA for fine-tuning
Build retrieval-augmented generation systems for private knowledge
Evaluate accuracy, groundedness, safety, latency, and cost
Deploy, monitor, secure, and maintain production-ready LLM systems

Proof

This book is built for AI engineers, ML engineers, software developers, data scientists, backend engineers, technical founders, and advanced students who want more than prompt experiments. With step-by-step workflows, runnable code examples, project structure, checklists, and a capstone production LLM system, it gives you the practical confidence to design, ship, and operate real AI systems.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
