If the threshold for e-e+ pair production depends on an angle between photon momenta, and if the γ-rays are collimated right in gamma-ray burst (GRB) source then another solution of the compactness problem is possible. The list of basic assumptions of the scenario describing the GRB with energy release < 1049 erg is adduced: the matter is about an alternative to the ultrarelativistic fireball if all long-duration GRBs are physically connected with core-collapse supernovae (SNe). The questions about radiation pressure and how the jet arises on account of even a small radiation field asymmetry in a compact GRB source of size \lesssim 108 cm, and observational consequences of the compact model of GRBs are considered.
