Intelligent Delivery: Making Every Unit of Compute Serve Better Ads

By · Published by Everything Blog

In short

Intelligent Delivery functions across heterogeneous hardware fleets, models, and ranking stages to optimize compute based on user intent, candidate quality, and system conditions. The architecture employs multi-layered mechanisms alongside agentic AI to continuously balance resources across boundaries. Transitioning from coarse manual segmentation rules to a shared machine learning intelligence layer improved the identification of highest-value compute opportunities by approximately 20%.

- Ads ranking models are growing toward LLM scale faster than the hardware to run them can keep up. An extra unit of compute has more impact on some ad requests, models, and chips than on others. The challenge is deciding where to allocate it to get the best outcome for the entire system.

- We built Intelligent Delivery, an ML-driven system that allocates resources across the serving stack toward the system-wide optimum. It has delivered ~10% incremental ranking performance on top of model and system advancements since 2017.

- We’re sharing a few of Intelligent Delivery’s capabilities: how we build ML models to predict the marginal utility of compute, multi-layered mechanisms to move resources across the system, and how we increasingly leverage agentic AI to continuously detect and respond to system shifts.

As frontier ads ranking systems advance toward larger models, broader candidate sets, and richer delivery architectures, they also place greater demands on serving efficiency. Compute resources do not scale at the rate that models and system complexity do. The challenge is not just how to build more…
