Amazon uses LLMs for catalogue-scale product listing quality control
Amazon's traditional specialized ML models, each optimized for an independent product category, handled simple structured attributes well but could not scale to products with complex or nuanced attributes, which required specially trained models or costly manual review.
How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · Catalogue summarization
The entire catalogue is summarized and organized by product type and attribute value to build knowledge for the LLM.
Tools used
large language models
Outcome
LLM-based quality control now corrects and updates product attributes at the scale of Amazon Stores, includes the latest seller values within days, saves thousands of hours in human reviews, and extends coverage to more languages.
