  Along this paper we show that under certain conditions the method for
describing of solvable Lie and Leibniz algebras with maximal codimension of
nilradical is also extensible to Lie and Leibniz superalgebras, respectively.
In particular, we totally determine the solvable Lie and Leibniz superalgebras
with maximal codimension of model filiform and model nilpotent nilradicals.
Finally, it is established that the superderivations of the obtained
superalgebras are inner.
