## AI overview

This article describes an event-driven architecture for turning changing customer and claims data into timely, auditable next-best-action recommendations for retention. It separates ingestion, feature computation, model scoring, decisioning, and activation, combining streaming and batch paths with Snowflake, Databricks, PySpark, and Python.
