  The canonball model, which unifies cosmic ray bursts (CRBs) and gamma ray
bursts (GRBs), is used to predict the maximum isotropic equivalent gamma ray
energy release in a GRB. The predicted maximum is based on the observed knee
around 1 TeV in the energy spectrum of Galactic cosmic ray electrons, and on
the Amati correlation in GRBs. Both were predicted by the cannonball model of
CRBs and GRBs before their empirical discoveries. The predicted maximum agrees
well with that concluded from up to date GRB observations.
