CPU bottlenecks, high cost, and low experimentation leading to slow innovation

Key challenges

The client struggled to scale Hierarchical Bayesian Regression (HBR) on CPU-based infrastructure. Long runtimes, approximately 12 hours and high costs, limited experimentation and delayed insights. The inability to efficiently process large-scale hierarchical data hindered business agility and model adoption.
