IMHO, the Grimm, in their 'normal' state, have approximately the same intelligence a the animals they somewhat resemble. The only real difference is that I don't think they are 'natural' creatures. Instead, I think they may be some kind of artificial construct, either from some application of Dust (the same one that gives the AK-130s and Spider Droids their animation) or some other means not known to the humans of Vytal. This is why those Mk1 Beowolves in the Red Trailer just disintegrate after they're killed. What Pyrrha meant when she said that the Creatures of Grimm have 'no souls' is that they're not really alive in the strictest sense of the word. They're more like golems - lifeless replicas given a semblance of life by some unknown power.

I have no proof of this except the continual references to the 'lights' and the names of some of the Hunter academies. However, I suspect that the Grimm can be controlled by an external sentience, possibly a non-corporeal one, that can co-ordinate them and turn them into a formidable army. The light of the beacons currently holds it back and stops it from taking control; if it were able to influence matters, those Grimm the kids encountered in the forest would have been hundreds of times more dangerous.
