We outline the ab initio no core shell model and present recent results. Nuclear properties are evaluated with two-nucleon (NN) and three-nucleon interactions (TNI) derived within effective field theory (EFT) based on chiral perturbation theory (ChPT). Fitting two available parameters of the TNI generates good descriptions of light nuclei. In another effort, referred to as the ab exitu approach, results are obtained with a realistic NN interaction derived by inverse scattering theory with off-shell properties tuned to fit light nuclei. Both approaches produce good results for observables sensitive to spin-orbit properties. In a third approach, we supplement the derived realistic effective interaction with phenomenological NN interaction terms with the goal to describe spectra of fp-shell nuclei in the limited basis spaces currently available.
