Models out of the box have trouble reviewing DoorDash’s codebase, even when feeding them appropriate context. Single-pass AI reviewers only caught 30% of the real issues in our PRs. Instead, we built a multi-model (Sonnet 4.6 + Opus 4.8) code review agent that caught 53.6% issues at $3.91 a PR (most enterprise code review solutions perform significantly below 50% recall on DoorDash PRs). Today, we’re proud to share DashBench, our internal benchmark to compare multi-model/harness code review systems against each other. DashBench has given us confidence in maximizing the intelligence per dollar we’re spending on AI tokens to ship code safely.

We’ve been experimenting with this build in iMessage. Text it to order or have it proactively tell you what to get. Useful?

Today we’re launching Ask DoorDash — a new conversational way to search the app in your own words through chat, voice, a recipe link or photo. Ask DoorDash can build you a grocery cart ~5x faster than doing it manually. It takes a single prompt to complete your cart in under 2 minutes. In early testing, nearly half of all restaurant orders made with Ask DoorDash were from a place the customer had never ordered from before, and grocery baskets built with Ask DoorDash were over 35% larger than those without.

We ran out of whiteboard space and are on the walls @AIatDoorDash Come push the frontier with us - we’re looking for summer and fall research fellows. Any education or experience level, unlimited compute, mentorship from senior researchers, and full publication support + a very generous stipend.

Today we are welcoming the Metis team to DoorDash as part of DoorDash AI Research. For the past six months, DoorDash has partnered with Metis to build AI agents together, and we have been consistently impressed by their team. By joining forces, we aim to accelerate our plans on building agentic commerce and pushing the frontier of physical intelligence. Excited to share more there soon. It’s still early innings with how AI will transform local commerce, and we’re looking forward to exploring those possibilities together with Aryan, Aayush, Marcus and the Metis team!
