Source Intelligence Dashboard - AI March Madness 2026

The Source Intelligence dashboard tracks every citation URL that GPT-4o, Gemini 2.5, and Perplexity Sonar Pro return in their NCAA Tournament prediction responses. Each source domain is ranked by total citation count and broken down by model.

Citation patterns reveal each model's evidence base. GPT-4o concentrates on 5 to 6 major sports media domains including ESPN and CBS Sports. Perplexity spreads citations across 15 to 20 domains including niche analytics sites like KenPom and Barttorvik. Gemini sits between the two, mixing official NCAA statistics with national coverage.

Source type categorization classifies each domain as major media, analytics, social media, team official site, or proprietary knowledge. Models that cite narrower source sets tend toward higher confidence scores but not necessarily higher accuracy, creating a calibration red flag.

Source Fingerprint

The unique pattern of citation domains each AI model relies on for its predictions.

Citation Density

The average number of source URLs cited per prediction response by each model.

Source Overlap

The percentage of citation domains shared between two models. Low overlap indicates uncorrelated evidence bases.
