In a head-to-head competition, ChatGPT emerged as the victor in a logic puzzle challenge against Google’s Gemini, Microsoft’s Copilot, and Elon Musk’s Grok. The puzzle, based on a Burger King promotional image (available at https://imgur.com/M9zofCQ), required the AI models to deduce the answer: 427. While ChatGPT successfully solved the riddle, the other models faltered, with Gemini’s particularly verbose and inaccurate response drawing attention. The test, shared by Reddit user /u/reebokLFR on the r/artificial intelligence subreddit (https://old.reddit.com/r/artificial/comments/1od9aw5/i_gave_four_popular_ai_models_a_challengeonly_one/), highlights ongoing debates surrounding the strengths and limitations of current AI reasoning capabilities.
