How DoorDash Built an AI Shopping Assistant That Doesn’t Rely on the LLM Alone
Summary

DoorDash's Ask DoorDash assistant uses a runtime orchestrating specialized agents via MCP, with three memory systems (long-term, session, agentic) for personalization. Production results showed 24% higher grocery checkout conversion and 17% larger baskets, while an automated evaluation framework—simulating stateful conversations with LLM-generated users—scaled to 2,000+ daily evaluations, cut regression testing from 6 hours to 20 minutes, and validated a 35% latency reduction model migration.
