In this paper, we discuss the construction of integrable BCS models in the framework of the quantum inverse scattering method. Specifically, the reduced BCS model, which is based on the su(2) algebra, a model of two coupled BCS systems, based on the su(4) algebra and an extended pairing model associated to the u(2|2) symmetry are presented.
