Question

Iron man suit has A.I. called Friday . But Rodies suit no A.I. then how it works.?

Answer 1

Ironmans suit has AI Zarves not Friday,Friday is a secondary A.I. used by Ironman

Answer 2

The War Machine armor was a prototype stolen by Rhodey and allowed by Tony to keep it. He probably doesn't have the A.I. because the suit was modified by the government and Tony didn't want the government to have Jarvus or Friday.
