  We describe a comparison between pretriangulated differential graded
categories and certain stable infinity categories. Specifically, we use a model
category structure on differential graded categories over k (a field of
characteristic 0) where the weak equivalences are the Morita equivalences, and
where the fibrant objects are in particular pretriangulated differential graded
categories. We show the underlying infinity category of this model category is
equivalent to the infinity category of k-linear stable infinity categories.
