We construct a huge number of anomaly-free models of six-dimensional N = (1,0) gauged supergravity. The gauge groups are products of U(1) and SU(2), and every hyperino is charged under some of the gauge groups. It is also found that the potential may have flat directions when the R-symmetry is diagonally gauged together with another gauge group. In an appendix, we determine the contribution to the global SU(2) anomaly from symplectic Majorana Weyl fermions in six dimensions.

Global anomalies in $6D$ gauged supergravities
New anomaly-free six-dimensional R-symmetry gauged supergravities are presented, and global anomaly freedom is shown to impose the constraints n_V ≡ 8 mod 12 (U(1)_R) and n_V = 60 (Sp(1)_R).

Diagonally gauged anomaly-free 6D supergravities and their vacua
Bounded scans yield 706 single-factor and 1559 two-factor anomaly-free 6D (1,0) models gauged by a diagonal U(1)_R+, and explicit supersymmetric Minkowski vacua for a subset.

4D de Sitter from 6D gauged supergravity with Green-Schwarz counterterm
6D gauged supergravity with the Green-Schwarz counterterm admits exact dS4×S2 and Mink4×S2 solutions (with a monopole); the de Sitter vacuum has two tachyons and flows to Minkowski.

Rational points in the 6d supergravity landscape and simple current extensions
Rationality of the 2d SCFT on BPS strings provides a consistency criterion that uniquely determines the elliptic genus and global gauge group in a class of 6d supergravity models without tensor multiplets.
