Primordial gravitational waves have the potential to shed new light on the very early universe. In this talk I discuss gravitational wave production in a variety of inflationary models beyond the simplest, single-field, scenarios and highlight some of their implications for testing inflation with interferometers. I also discuss how anisotropies in the gravitational wave energy density can be a powerful tool in characterizing the inflationary gravitational wave background and potentially distinguishing it from backgrounds due to other sources.
