LLM structured output validation guide prevents production failures

This guide explains how to implement a robust validation layer for structured output from Large Language Models (LLMs) to prevent production system failures. It highlights common issues like extra text around JSON, missing fields, or incorrect data types, emphasizing that LLM APIs offer syntax help but don't guarantee business logic adherence. The article advocates for an 'output contract' with three layers—syntax, schema, and business rules—to ensure data safety and reliability before it impacts downstream systems. AI
