DoorDash AI Assistant Architecture: Tools and Memory in Prod
xiaohu · x · 2026-07-15
DoorDash has published an engineering blog for its AI shopping assistant, Ask DoorDash, detailing its runtime architecture, memory system, and evaluation framework. Users can describe their needs in natural language, and the AI will assist in searching restaurants, planning meals, and creating shopping carts.
Rather than being built as a standalone system, it adds a layer to the existing platform. The overall architecture is divided into four layers, with business logic kept independent and excluded from prompts to ensure system maintainability and stability.
