Given the extraordinary success of Planck and the stringent constraints it has placed on many models of non-Gaussianity, one might be forgiven for giving up hope of using the CMB to probe the initial conditions of the universe. However, I aim to convince you not to throw your non-Gaussian model in the bin just yet! I will describe some recent (but incomplete) work on the CMB trispectrum, as well as attempts to provide a framework to constrain all models of single field inflation.
