How to use Laravel model NOT to work with a table?

Question

ORM

Hello! Recently began to study Laravel, and then a question related to models appeared.
As I understand it, in Laravel models use ORM - Eloquent, i.e. each model is a database handler.
But what if I need to use the model not to work with the database, but to perform other operations? For example, processing images and issuing a result without writing to a table. What should be done in terms of the architecture of this framework?
