Gromov-Witten invariants can be interpreted as a (virtual) counting of curves on a complex projective variety, so they are biregular invariants.
However, they are not birational invariant in general. The behaviour of Gromov-Witten invariants under an arbitrary birational modification is in fact rather subtle. For more details and examples you can have a look at Section 1.4 of the paper
