We give an overview of the mixed-precision Krylov strategies of QUDA. These have evolved over the past decade and utilize a variety of numerical techniques to stabilize the convergence of solvers such as Conjugate Gradient. We describe a recently developed bit packing technique to increase precision at fixed word size. This improvement in precision stabilizes the mixed-precision solvers as the chiral limit is reached.
