## Summary

Meta says Intelligent Delivery is an ML-driven system that allocates compute across its ads serving stack and has contributed about a 10% ranking performance gain since 2017. The system uses the Resource Core Model, a 6B sparse and 20M dense parameter model that runs before candidate retrieval to predict which ad requests benefit most from additional compute.
