    Overview

    AI hallucination — where an AI system generates plausible but false information — is one of the most significant risks in professional AI deployment. In legal, tax, and medical contexts, hallucinated citations, fabricated precedents, or incorrect factual claims can have serious consequences.

    Why AI Hallucinations Occur

    • •LLMs predict probable text sequences, not verified facts
    • •Training data gaps create knowledge blind spots
    • •Complex or rare queries push models beyond reliable boundaries
    • •Lack of grounding in authoritative source material

    Mitigation Strategies

    • •Use RAG architecture to ground responses in authoritative sources
    • •Implement citation verification systems
    • •Establish human review protocols for all AI outputs
    • •Use purpose-built professional AI systems rather than general-purpose tools
    • •Train professionals to identify potential hallucinations

    Frequently Asked Questions
