Original titleThe Thin Orchestrator: How We Made Our AI Agents More Reliable by Giving the Router Less to Do
AISummary
Meta says it built a 1,300-line orchestrator that routes 20+ workflows to 14 specialized AI agents and performs no domain work itself. The company reports that configuration prep for a new column dropped from three to four days by hand, and about a day with its earlier system, to under an hour. It also says about two-thirds of the system's changes land without significant human edits.
