Overview

Reduce risk from unreliable AI outputs by learning how to detect hallucinations, verify claims, ground responses with RAG, design prompt guardrails, and monitor LLM workflows before flawed answers reach users or decisions.

Key Features

  • Detect fabricated facts, weak citations, outdated claims, and unsafe AI outputs
  • Use prompt guardrails, RAG, NotebookLM-style grounding, and model checks to improve LLM reliability
  • Apply fact-checking, escalation, logging, and monitoring for safer AI adoption
  • Purchase of the print or Kindle book includes a free PDF eBook

Book Description

AI systems that sound confident can still be wrong. Managing AI Hallucinations gives you a structured, code-driven approach to identifying, preventing, and verifying unreliable LLM output before errors reach users or decisions.

Written by Arkadiusz Włodarczyk, a programming instructor and course creator with 20+ years of experience, the book works through real code examples and walkthroughs. You will learn why language models produce fabricated facts, false references, and overconfident code. You will reduce hallucinations through system instructions, constraints, and few-shot prompting, and ground responses in trusted sources using RAG, vector databases, and NotebookLM. Cross-model comparison, source checks, and self-consistency prompting give you repeatable ways to evaluate claims.

Later chapters cover guardrails, output validation, logging, and fallback layers alongside compliance requirements, bias risks, and escalation criteria for responsible deployment. The book closes with a monitoring project built on OpenTelemetry, Prometheus, and Grafana. By the end, you will be able to design and monitor AI workflows that catch failures before they reach users.

What you will learn

  • Explain why LLMs hallucinate and what makes outputs unreliable
  • Detect fabricated facts and false references before they spread
  • Reduce hallucinations with prompts, constraints, and guardrails
  • Ground responses in trusted sources using RAG and vector databases
  • Verify claims with source checks and model comparison for accuracy
  • Build reliable AI systems with guardrails, logging, and fallbacks
  • Apply compliance checks and bias tests for responsible deployment
  • Monitor LLM apps in production with OpenTelemetry and Grafana

Who this book is for

This book is for Data scientists, AI engineers, developers, technical leads, product managers, compliance professionals, and business teams adopting LLMs in code, content, research, analytics, or decision-support workflows. This book is useful for those who need practical methods to reduce AI hallucinations, validate outputs, and communicate AI limitations clearly. No advanced programming experience is required, but familiarity with LLM tools, APIs, JSON, or command-line workflows will help.
