+## TL;DR
+
+- Endpoint Configurations depend on a Model.<br/>
+  They are deleted if the Model they depend on changes.
+- Serverless Endpoints' backend use **a snapshot** of the Endpoint Configuration at the time each host is created.<br/>
+  To make a serverless Endpoint use a new Configuration or Model, its hosts need to be replaced.
