Near the tip of the AGB we find the optical Mira variables and also the OH-IR stars. Observational data on the luminosities, periods, and population membership of the OH-IR sources are beginning to be available; in principle this information should constrain AGB models very strongly. In practice, current data are found to be insufficient to unambiguously determine the relation between Miras and these sources; in fact three very different interpretations are currently possible.
