What is Asked ChatGPT to fill out an NCAA bracket on opening day. It invented 33 teams and needed 3 correction prompts to fix.?

Model Madness is an experimental platform that pits leading AI models—Claude, ChatGPT, Gemini, and Grok—against each other in predicting the NCAA March Madness tournament. The experiment, conducted on the opening day of the tournament, assesses each AI's ability to generate an accurate bracket based on real-world data. It highlights significant differences in AI performance, with some models fabricating teams or misplacing them, requiring multiple correction prompts. The tool tracks live results, compares AI picks to public percentages, and provides a visual bracket view, offering insights into AI's current capabilities and limitations in handling dynamic, factual information.

Best used for

Ideal for developers and data scientists who need to evaluate AI model accuracy in dynamic, real-world scenarios, and for content creators interested in AI's current capabilities. Especially valuable for understanding AI hallucination patterns and the necessity of prompt correction when dealing with factual, time-sensitive information.

FAQs

Which AI models are included in the Model Madness experiment?

Model Madness evaluates predictions from four prominent AI models: Claude, ChatGPT, Gemini, and Grok. The experiment compares their ability to accurately predict the NCAA March Madness tournament outcomes based on prompts given on the first day of the tournament.

How does Model Madness assess AI bracket accuracy?

The tool checks if each AI model correctly identified all 64 teams in the tournament field and placed them in the right regions. It also notes if any fabricated teams were included or if the bracket structure had issues, documenting the number of correction prompts needed.

Can I see how the AI picks compare to public predictions?

Yes, Model Madness includes a feature that compares the AI models' champion picks and overall bracket percentages against those from the ESPN Bracket Challenge. This provides insight into how AI performance stacks up against the general public's predictions.
