Building AI Applications with Foundation Models: Create Real-World LLM, RAG, Agent, and Multimodal Apps from Prototype to Production

Build AI apps that move beyond flashy demos and hold up in real software projects.

Many developers can call an AI API. Fewer know how to turn that model call into a reliable application with clean code, structured outputs, retrieval, tool use, evaluation, security, and deployment.

Are you tired of tutorials that stop at a chatbot? Do you want to build LLM apps, RAG systems, AI agents, and multimodal workflows that can actually support users, documents, tools, and production requirements?

Building AI Applications with Foundation Models gives you a practical path from setup to deployment. Instead of vague theory, this book shows how to build working AI application layers around foundation models using Python, FastAPI, prompt engineering, embeddings, vector search, retrieval-augmented generation, tool calling, agents, multimodal processing, testing, guardrails, and production workflows.

You will learn how to:

• Set up a clean AI engineering workspace
• Build reusable model clients and structured prompt workflows
• Create semantic search and private-document RAG apps
• Connect AI systems to tools, files, databases, and APIs
• Build controlled agents with limits, logs, and approval points
• Add evaluation, security, monitoring, and deployment practices

This book is written for developers, builders, technical founders, software teams, and advanced learners who want practical AI engineering skills without training models from scratch.

Each chapter builds toward real-world application patterns: document assistants, business tools, multimodal review workflows, production APIs, and deployment-ready systems.
