I will start with an overview on the methods to obtain large non-Gaussianity in models in which multiple scalar fields are present during inflation. I will then discuss concrete models that lead to large non-Gaussianity, and their observational consequences. I will end with some proposals to embed these models of inflation in a fundamental theory such as string theory.
