Soft QCD is beyond perturbative control, and therefore phenomenological models have to be developed. These are implemented and combined within event generators. Typical aspects considered are multiparton interactions, colour reconnection, and hadronization. Of special interest are non-universal features of hadronization at the LHC, such as the recently observed enhancement of charm and bottom baryons, and the bottom baryon asymmetry, as well as the some years earlier observed strangeness enhancement. Several new production mechanisms, such as junction reconnection, ropes and shove, have been proposed to address some of these issues. Alternatively, an admixture of a quark--gluon plasma component also in pp collisions is introduced in the core--corona approach.
