Instacart Builds Blueberry, an AI-Powered Assistant to Help On-Call Engineers Investigate Incidents
Not a pilot. Instacart deployed AI agents across incident response—parallel subagents generating root-cause hypotheses in real time.
Why it matters
Autonomous agent systems are moving from research into production reliability engineering. Instacart's Blueberry shows how agents can handle high-stakes, multi-step investigative work while keeping humans in control—a template for enterprise agent deployment at scale.
The key facts
