How to check registered sling models classes in AEM?

Sling Models are annotation driven Java "POJO's" (Plain Old Java Objects) that facilitate the mapping of data from the JCR to Java variables and provide a number of other refinements when developing in the context of AEM (Adobe Experience Manager).

Sling Models Bound to Resource Types and can be explored and view in Felix console using the below path. And can be accessed on Felix console > Status > Sling Models
