  In this article we briefly survey some developments in gauged linear sigma
models (GLSMs). Specifically, we give an overview of progress on constructions
of GLSMs for various geometries, GLSM-based computations of quantum cohomology,
quantum sheaf cohomology, and quantum K theory rings, as well as
two-dimensional abelian and non-abelian mirror constructions. (Contribution to
the proceedings of Gauged Linear Sigma Models@30 (Simons Center, Stony Brook,
May 2023).)
