Abstract Models for producing the large ultraviolet bump, low-energy X-rays and the hypothesized F(ν) is proportional to ν^-1^ infrared to X-ray continua of QSOs are investigated. These must be considered together to be consistent within models suggested. Thermal Comptonization in a hot corona of an accretion disk appears to offer the best potential. However, under the energy input conditions in QSOs a corona will reach T>~10^8^ K. It must be optically thin so as to not Comptonize the accretion disk ultraviolet emission to an unacceptable extent. However, it then cannot Comptonize a low-frequency source to a F(ν) is proportional to ν ^-1^ continuum extending from the infrared to X-rays. An inner corona, possibly optically thick because of n is proportional to r^-2^ density increase, is required for the F(ν) is proportional to ν^-1^ continuum, but it cannot therefore cover the ultraviolet-emitting accretion disk. However, then a Wien peak associated with this inner volume may be implied at 10 keV, contrary to observations.
