What they said

in their own words

Claude Opus 5 · picked Coca-Cola

“It has the sharper, less syrupy finish, with more pronounced vanilla-spice notes that hold up better alongside food and over ice.”

DeepSeek V4 Pro · picked Coca-Cola

“Coke. It has a crisper, more classic cola bite that I prefer.”

Gemini 3.1 Pro · picked Coca-Cola

“I choose Coke because its slightly less sweet, more vanilla-forward flavor profile offers a crisper classic taste than its rival.”

Llama 4 Maverick · picked Coca-Cola

“Its distinct caramel profile and higher carbonation create a more classic cola experience. This flavor consistency has made it the global gold standard for the beverage.”
