We conjecture an intrinsic UV cutoff for the validity of the effective field theory with a large number of species coupled to gravity. In four dimensions such an UV cutoff takes the form A = root lambda/NM(p), for N scalar fields with the same potential lambda phi(4)(i), i = 1,..., N. This conjecture implies that the assisted chaotic inflation or N-flation might be in the swampland, not in the landscape. Similarly an UV cutoff Lambda = gMp/root N is conjectured for the U(1) gauge theory with N species.
