Inhaltsangabe

Every engineer who has shipped a working AI demo knows the feeling. The chatbot runs cleanly on handpicked test data, the team celebrates, and someone posts a screenshot with fire emojis. Then Monday arrives — real users, real traffic, inputs that look nothing like the weekend test cases. Latency spikes. Token costs compound unexpectedly. Hallucinated answers reach paying customers. Logs reveal nothing useful when failures occur. There is no reliable signal that any change — a prompt tweak, a model swap, a chunk-size adjustment — actually made things better or worse. The gap between a demo that impresses a room and a system that earns user trust over months is not a polish problem. It is an architectural difference, and almost everything the internet teaches about building with AI gets engineers only as far as Friday. This book is about the weeks and months that follow.

Inside this book, readers will learn how to:

• Architect a complete six-layer production AI system — data, model, retrieval, orchestration, application, and governance — and defend every decision in a real design review
• Build Retrieval-Augmented Generation pipelines that scale from prototype to production volume using hybrid dense-plus-sparse search, cross-encoder re-ranking, and honest offline-to-online evaluation — never trusting demo-set metrics as a proxy for production quality
• Design agentic systems with hard step limits, cost ceilings, loop-detection logic, and structured tool validation that prevent autonomous workflows from becoming runaway cloud bills
• Manage prompts as versioned, tested production artifacts — with CI pipelines, rollback paths, prompt registries, and code-review discipline that catches silent regressions before users do
• Apply parameter-efficient fine-tuning with LoRA when adapting a foundation model is genuinely the right decision, and know precisely when prompting or RAG is the better engineering choice
• Set latency budgets, instrument per-request serving costs, and implement streaming delivery that makes multi-second model calls feel nearly instantaneous to end users
• Build honest evaluation harnesses — offline retrieval metrics, LLM-as-judge pipelines, and human review workflows — that detect quality degradation before it reaches production
• Apply layered safety controls covering prompt injection, hallucination, citation drift, and output validation to protect users and the business from every failure mode that matters in production
• Navigate the AI Engineer job market with a structured interview framework and three portfolio-ready capstone projects, or execute a solo AI product from concept to paying users in weeks

The practical reality of professional AI engineering is that the model call itself represents roughly ten to fifteen percent of total engineering effort. The remaining work lives in the surrounding system: the retrieval pipeline that determines what the model sees, the evaluation harness that measures whether outputs are improving, the serving infrastructure that keeps latency and cost within acceptable limits, and the safety layer that makes the entire system safe to put in front of real users. These are the layers most tutorials never enter — and the layers every production AI team lives in every single day.
