Full Prediction History - AI March Madness 2026

Complete searchable log of every prediction made by GPT-4o, Gemini 2.5, and Perplexity Sonar Pro across all 2026 NCAA Tournament games. Each entry records the predicted winner, confidence score, collection window (T-24h, T-6h, or T-1h), and whether the prediction was correct.

Filter predictions by tournament round (First Four through Championship), by AI model, or by outcome (correct, incorrect, pending). This log provides the raw data underlying all accuracy calculations, calibration curves, and drift analyses across the tournament.

All predictions are collected automatically via scheduled cron jobs that query each AI model through the OpenRouter API with identical prompts. The prediction log updates continuously as new collection windows open before each game.

Prediction Record

A single prediction entry containing model ID, game ID, predicted winner, confidence score, collection window, and outcome.

Collection Window

One of three time points (T-24h, T-6h, T-1h) at which each AI model is queried for its prediction.
