Subway Has Entered the ChatGPT: Third AI-Generated Poster Takes on McDonald's and Burger King

The long-standing advertising tete-a-tete between McDonald's and Burger King welcomed a third player over the weekend, as Subway entered the latest string of tactical executions with its own ChatGPT-led creative.

Created by Saatchi & Saatchi, the latest spot for Subway also used AI to generate a copy-led execution, comparing the icon-status and size of the fast food giants’ best loved menu items.

In response to the questions posed by McDonald's and Burger King’s spots, Subway asked the chatbot how a McDonald’s Big Mac and a Burger King Whopper ‘compare to a footlong?’, and ChatGPT’s response is presented in bold, brand-led typography: “In terms of size, both are significantly smaller than a footlong sandwich.”

Kirstey Elston, marketing director UK & Ireland, Subway said: "If there's going to be a conversation on iconic sandwiches, Subway will of course get involved. What can we say - even ChatGPT knows our Footlongs are the biggest and best sandwich out there!"

Franki Goodwin, chief creative officer, Saatchi & Saatchi added: “There’s a lot of chat about ChatGPT and, while we try not to get too caught up in hype trends, we couldn’t resist getting in on this conversation. It's a big moment for Subway with the launch of the new Series menu, and what can we say - ChatGPT says they’re the biggest too.”
