There are various synonyms for "world models" that can be used depending upon the context. Some of the most commonly used words include "cosmologies," "worldviews," "paradigms," and "philosophies." Cosmologies refer to the theories and concepts about the origins and nature of the universe, whereas worldviews may include beliefs and values that shape one's perspective on the world. Paradigms are defined as frameworks or models that establish a way of thinking or viewing the world. Philosphies are also similar but usually encompass more broad and fundamental principles of a particular ideology. Ultimately, the synonym used should depend on the context in which it's being used and the meaning being conveyed.
