AI Model Profile - NCAA Tournament 2026

Detailed performance profile for an AI prediction model tracking the 2026 NCAA Men's Basketball Tournament. Shows accuracy by round, confidence calibration, source citation patterns, and prediction drift analysis.

Three AI models are tracked: OpenAI's GPT-4o (gpt-4o-search-preview), Google's Gemini 2.5 Pro (with Google grounding), and Perplexity's Sonar Pro. Each model receives identical prompts at three collection windows (T-24h, T-6h, T-1h) before every game.

Model profiles include a radar chart of key performance metrics, accuracy breakdown by tournament round, top cited sources, and head-to-head comparison against the other two models.
