LLM Engineering in PRODUCTION: From Context Windows to Multi-Agent Fleets

By Pavel Yuri

LLM Engineering in Production is written for professional software and ML engineers, it goes beyond demos and quickstarts to address the real engineering problems: reliability, cost, evaluation, safety, and the operational discipline required to ship LLM systems that hold up under real-world pressure.

Inside this book, you'll learn how to:

Master context engineering - the discipline that has replaced prompt engineering as the core skill in production LLM workDesign and operate RAG pipelines with hybrid search, re-ranking, and provenance trackingBuild rigorous evaluation frameworks from first principles, including LLM-as-judge techniquesMeasure and mitigate hallucination using grounding strategies and structured attribution patternsRoute intelligently across model fleets to balance cost, latency, and capabilityRed-team your systems against prompt injection, jailbreaks, and data exfiltration risks

Along the way, you'll build:

A structured model selection framework covering frontier APIs and open-weight modelsRegression testing pipelines that integrate with CI/CD and survive provider version changesCompliance-ready audit trails and data privacy patterns for regulated environmentsMulti-agent architectures designed for reliability, not just demos

This book is for engineers who are comfortable with production systems and want to apply that discipline to LLM development. It doesn't make the field sound easier than it is - it explains why the hard problems are hard, what current best practice looks like, and what your realistic options are. Anchored to the 2026 production landscape, it focuses on principles and patterns that outlast any individual model release.
