LLM Contracts Ensure Accurate JSON for E-commerce Product Tagging

This article proposes a method for ensuring accurate JSON output from Large Language Models (LLMs) when used for e-commerce product tagging. It suggests treating the LLM as an untrusted proposer and implementing strict validation checks for JSON structure, label sets, and business rules before committing tags. The approach emphasizes defining output contracts, normalizing input data, and separating parsing from validation to handle operational failures effectively. AI
