At the start of the Analytic, Kant says that in general logic, reason is the division of the higher faculties of cognition that deals with inference. This does not carry over to transcendental logic since the transcendental use of reason is not valid according to Kant. I’m not sure how this plays out, but it is worth noting that Kant ties the operation of reason to making inferences. I’d like to know more of what Kant says on inference, but there doesn’t seem to be any one place in the Critique (or the Logic or the Prologomena) that he discusses inference in detail.
