  During the last 15 years, a standard paradigm has emerged to explain both the
progenitor nature and the observed radiations of gamma-ray bursts. In this work
we show three GRBs for which the standard paradigm could be tested with high
statistics due to their exceptional spectral and temporal coverage. While GRB
1110205 represents a very good example of the standard scenario, GRB 090102 and
GRB 111209A do not fit into the standard paradigm.
