Idea

The notion of model (,1)(\infty,1)-category (or model \infty-category, for short) is the ( , 1 ) (\infty,1) -categorification of that of model category.

Where the classical model structure on simplicial sets is an archetypical example of a model category, so simplicial \infty -groupoids (“simplicial spaces”, bisimplicial sets) form an archetypical example of a model \infty-category. In this example, a fundamental application of the theory says, for instance, that geometric realization preserves homotopy pullbacks of homotopy Kan fibrations (see there).
