Large Language Models: From Foundations to Production AI Applications

Learn how to build real-world AI applications with Large Language Models—from foundational concepts to production deployment.

Large Language Models (LLMs) such as GPT, Claude, Gemini, Llama, Mistral, and DeepSeek are transforming software development, business automation, search, content generation, and enterprise AI. Organizations are rapidly adopting these technologies, creating strong demand for professionals who understand how to build, deploy, and manage AI-powered solutions.

This practical, hands-on guide provides a complete learning path for mastering modern LLMs and Generative AI. Rather than focusing only on theory, the book emphasizes real-world implementation, architecture patterns, best practices, and production-ready applications.
