## TL;DR
- Endpoint Configurations depend on a Model.
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.
To make a serverless Endpoint use a new Configuration or Model, its hosts need to be replaced.
## Cost-saving measures
- Use a single endpoint for multiple models where it makes sense.
- Delete endpoints when they are not used anymore.
