  The hybrid model is the Landau-Ginszburg-type theory that is expected, via
the Landau-Ginzburg/Calabi-Yau correspondence, to match the Gromov-Witten
theory of a complete intersection in weighted projective space. We prove a
wall-crossing formula exhibiting the dependence of the genus-zero hybrid model
on its stability parameter, generalizing the work of the second author and Ruan
for quantum singularity theory and paralleling the work of
Ciocan-Fontanine--Kim for quasimaps. This completes the proof of the genus-zero
Landau-Ginzburg/Calabi-Yau correspondence for complete intersections of
hypersurfaces of the same degree, as well as the proof of the all-genus hybrid
wall-crossing theorem, which is work of the first author, Janda, and Ruan.
