I briefly review the description of inclusive heavy hadron decays based on the inverse heavy quark mass expansion. In particular, I consider the transition B → Xu ℓ ν and the problem of extracting Vub, mainly as far as the separation from the background represented by b → c modes is concerned. I also discuss how to obtain complementary information from the decay mode B → Xs γ.
