Importance of models in theorizing: a deflationary semantic view

It is commonly acknowledged in science that model construction is one of the most important components of theorizing. Philosophers of science are gradually coming to acknowledge this situation, spurred on by holders of the semantic view of theories. In this paper I wish to defend a very deflationary version of the semantic view of theories, which is more or less a re-statement of the above commonplace. I reject the view encapsulated in the identity statement "scientific theories are families of models," although acknowledging the useful insights into science that holders of this strong position have given us.
