tl;dr:“Last year, we introduced the latest iteration to Robinhood: By leveraging proportional–integral–derivative (PID) controllers, Robinhood can now more quickly and effectively manage load imbalances. This has not only improved the reliability of our infrastructure, but yielded significant hardware cost savings. And with an increase in AI workloads that power our latest intelligent features, effectively managing demands on our GPU resources is more critical to the business than ever.”
