Abstract:Abstract. We show that the quasicategory of frames of a cofibration category, introduced by the second-named author, is equivalent to its simplicial localization.

“…Barwick and Kan constructed a model structure on and showed that it is Quillen equivalent to the Joyal's model structure on , in which fibrant objects are exactly quasi‐categories [, Theorem 6.12]. While there are many constructions assigning to a category with weak equivalences a quasi‐category that are equivalences of homotopy theories, by result of Toën [, Theorem‐ 6.2], all of them are equivalent either to the functor constructed by Barwick and Kan or its opposite (see also [, Remark 4.7]).…”

“…The third one [22] shows that it is possible to reconstruct a cofibration category from a cocomplete quasicategory in a way that establishes an equivalence between the homotopy theory of cofibration categories and the homotopy theory of cocomplete quasicategories. Moreover, in a paper joint with Chris Kapulkin [13] we prove that the quasicategory of frames models the simplicial localization of a cofibration category.…”
