STAGE 1 / 7— Anti-Pattern
Section 1: The LLM Anti-Pattern vs Right-Sized Model
The Naive Generative LLM Approach:
Prompting an LLM to follow a 20-step conditional rulebook for insurance eligibility.
Why It Fails in Production:
LLMs hallucinate logic, forget nested if-else constraints midway through the generation, and cannot be audited for regulatory compliance.
