The Thin Orchestrator: How We Made Our AI Agents More Reliable by Giving the Router Less to Do

Meta reports improved efficiency and accuracy in its data pipeline agents after deliberately keeping the orchestration layer thin, with the router only dispatching work and enforcing reliability checks while specialized agents handle domain reasoning. The company detailed the architecture in a post on Engineering at Meta published October 19, 2026.

Sometimes, giving an AI agent all of the knowledge it needs is the wrong approach. At Meta, we’ve seen notable improvements in efficiency and accuracy by keeping the orchestration layer of our data pipeline agents deliberately thin: It routes work and enforces reliability checks, while specialized agents do the domain reasoning. We’re sharing our own ...
