I discuss physical processes which may be important in the central engines of AGNs. Black hole accretion models have been elaborated during the past few years, and provide a plausible framework for jet and spectrum formation. However, the specific mechanisms responsible for producing the observed continuum radiation remain uncertain. I consider nonthermal models for the IR continuum, constraints on thermal plasma, and the production of relativistic electrons.
