McDonald's Brazil asked ChatGPT:
"What is the most iconic burger in the world?"
The neural network recognized the Big Mac as such, and the answer formed the basis for outdoor advertising.
A couple of days later, a symmetrical burundi cell phone database Burger King poster appeared nearby.
A competitor asked the neural network:

"Which one is the biggest?"
ChatGPT said it was "Whopper".
Burger vs. Mac 1
Subway suddenly joined the debate, asking to compare both burgers with its signature footlong. The chatbot acknowledged that the footlong was the winner in terms of size—a fact that was later documented in a nearby ad.
Burger vs. Mac 2
KFC put an end to the debate by posting its billboard next to its competitors. According to Colonel Sanders, it's not size, iconic status, or length that matters, but taste. And the neural network believes that the crispy burger outshines all others here.

In Russia: Lada vs. Hyundai
Automotive brands are traditionally the most active in marketing wars. Their peak came at the beginning of the 21st century, when Audi, BMW, and AvtoVAZ couldn't ignore their competitors. In 2016, the latter launched a provocative campaign for the Lada Vesta, verbally and visually alluding to the Korean brand Hyundai.
