We use the accretion disk/corona+jet model to fit the multi-band spectral energy distributions (SEDs) of two unusual radio-intermediate/quiet quasars. It is found that the optical/UV emission of III Zw 2 is probably dominated by the emission from the accretion disk. The X-ray emission should be dominated by the radiation from the jet, while the contribution of the disk corona is negligible. The optical/UV component in the SED of PG 1407+265 can be well modeled as the emission from the accretion disk, while the IR component is attributed to the thermal radiation from the dust torus with an opening angle of ∼50°. If the X-ray continuum emission is dominated by the synchrotron emission of the jet, the source should be a "high peak frequency blazar," which obviously deviates from the normal blazar sequence. The observed SED can also be fitted quite well by the accretion disk/corona model with the viscosity parameter α = 0.5. The spectrum of the accretion disk/corona in PG 1407+265 satisfies the weak-line quasar criterion suggested in Laor & Davis.
