Two billboards from Burger King and Mcdonald's have been placed next to each other in Brazil. According to translated versions of the billboards reported by The Drum, the chatbot calls McDonald's Big Mac the most "iconic burger" and names Burger King's Whopper "the biggest." The fast-food company asked OpenAI's chatbot what the most iconic burger in the world was and it named the Big Mac the "most globally recognized." The Burger King ad seems to follow McDonald's directly, asking: "And which is the biggest?" Burger King did not immediately respond to Insider's request for comment, made outside normal working hours.
