- DoorDash developed an LLM jury system that aggregates outputs from multiple language models to generate more accurate food item metadata, such as names, descriptions, and categories
- DoorDash applied context optimization techniques to refine LLM-generated metadata, incorporating restaurant-specific details like menu structure and regional naming conventions
- DoorDash integrated multimodal AI signals—including food images and text—to improve the accuracy of metadata generation, especially for ambiguous or culturally specific dishes
- DoorDash reported that the LLM jury approach outperformed individual models in consistency and correctness, reducing errors in dish classification and attribute tagging
Why it matters: Accurate food metadata directly impacts customer discovery and order accuracy at scale—DoorDash’s jury method improves AI consensus without human labeling costs, making search and recommendations more reliable across diverse menus while reducing operational friction for restaurant partners.
