Presentation: From Models to Agents: Building Context-Aware Consumer AI at Scale at DoorDash
DoorDash ditched one-shot predictions for agentic recommendations. Here's how consumer memory and semantic IDs changed the conversion game.

Why it matters
A major consumer platform moved from static ML to stateful agents that remember user context across sessions. This is a working deployment case study showing how agents handle real production scale and measurable business impact.
