There is an interface to various QM packages, but there is no native support for
QM without external software.

Vacuum is not a solvent, but you can certainly do vacuum simulations in Gromacs.

The limit is based mostly on available memory, but Gromacs' memory overhead is
pretty low. People routinely do simulations with millions of atoms.
