We show that in the decoupling limit of F-theory, the internal dimensions must be non-commutative. We develop tools to engineer GUT models in this set up and find that the value of 1/alpha_gut is predicted to be equal to the number of fuzzy points on the internal space. This strongly restricts the space of field theories that can arise as a limit of F-theory. We comment on the possible existence of a holographic dual description, and on the possibility of constructing models with low fuzzy KK scale, but with a high scale for quantum gravity.
