In this paper, we study the abelian complexity ρ n a b (t (k)) of generalized Thue-Morse sequences t (k) for every integer k≥ 2. We obtain the exact value of ρ n a b (t (k)) for every integer n≥ k. Consequently, ρ n a b (t (k)) is ultimately periodic with period k. Moreover, we show that the abelian complexities of a class of infinite sequences are automatic sequences.
