The renormalization program for Tensor Models is quickly reviewed. Then I will discuss a peculiar feature on the finiteness of open amplitudes of the colored Boulatov model on U(1) when endowed with a proper dynamics. In a second part, some recent results on polynomial invariants defined on Tensor Graphs generated by these models will be addressed.
