Description
Large Language Models (LLMs) are transforming the way individuals and organisations interact with technology, information, and knowledge. As these models become increasingly capable, the ability to communicate with them effectively is emerging as an important skill across education, research, business, and technology. Prompt engineering provides a structured approach to this interaction, moving beyond simple questions and instructions towards the deliberate design of prompts, workflows, and intelligent AI-powered systems.
This book, LLM Prompt Engineering: Design Patterns, Systems, and Real-World Applications, has been developed to provide readers with both a conceptual foundation and a practical understanding of prompt engineering. It begins with the fundamentals of LLMs, including tokens, transformers, and model behaviour, before progressing towards systematic prompt design and advanced prompting techniques.
The book treats prompts as programmable interfaces that can be designed, tested, evaluated, refined, and optimised. It explores techniques such as decomposition, structured reasoning, reflection, interactive prompting, and other design patterns for addressing complex tasks. It also extends beyond individual prompts to examine Retrieval-Augmented Generation, embeddings, orchestration frameworks, fine-tuning, and the development of scalable LLM-powered applications.
Particular emphasis is placed on real-world applications in enterprise automation, coding, data analytics, and document processing. The book also considers evaluation, safety, reliability, and governance, recognising that effective AI adoption requires both technical capability and responsible implementation.
Through practical examples, hands-on activities, experiments, frameworks, and projects, this book aims to help students, professionals, researchers, and practitioners develop the confidence to design meaningful LLM solutions and translate generative AI capabilities into measurable and sustainable outcomes.
