We give a brief and a critical review of the Barret-Crane spin foam models of
quantum gravity. Then we describe two new spin foam models which are obtained
by direct quantization of General Relativity and do not have some of the
drawbacks of the Barret-Crane models. These are the model of spin foam
invariants for the embedded spin networks in loop quantum gravity and the spin
foam model based on the integration of the tetrads in the path integral for the
Palatini action.
