The Pioneer Venus Orbiter (PVO) log [ital N]-log [ital P] distribution follows a [minus]3/2 power law for over a factor of 30 in intensity, which is inconsistent with Gamma-Ray Bursts from large redshifts. We develop log [ital N]-log [ital P] models suitable for cosmological gamma-ray bursts. The PVO data is best fit with a standard candle peak luminosity of 2[times]10[sup 50] erg/sec with 3[times]10[sup 4] events/yr within a Hubble distance. However, non-cosmological models fit nearly as well ([ital L][sub 0][much lt]10[sup 50]). A luminosity of 10[sup 52] erg/sec fits at a 3[sigma] level and is, therefore, a maximum upper limit allowed by the PVO data. This upper limit is roughly equal to other reported lower limits. The BATSE event rate combined with the PVO limits imply that evolution with epoch must be occurring.
