| Summary:
Arguably, the simplest chiral gauge theories are $mathrm{SO}(10)$ with $N_f$
fermion fields in the spinor representation {bf 16}. We study their dynamics
using their supersymmetric limits perturbed by an infinitesimal
anomaly-mediated supersymmetry breaking as a guide. We predict the theory is
gapped for $N_f=1,2$, while the $mathrm{SU}(N_f)$ global symmetry is broken to
$mathrm{SO}(mathrm{N}_f)$ for moderately large $N_f geq 3$.
