FightChoice.app gives free AI predictions for every UFC/MMA fight: a predicted winner, calibrated win probability, per-model breakdown, and predicted fight duration — in 7 languages. Each matchup runs through an ensemble of independent models (a graph neural network, gradient-boosted and logistic-regression models, and a rating model) blended into one calibrated probability.
Every prediction is committed before the fight and graded publicly after the result — no cherry-picking. Each pre-committed pick is timestamped ("locked in before the fight"), and the full accuracy is published so it can be verified rather than taken on faith.
"Verified" counts only picks committed before the fight. A separate retroactive backtest (202 settled fights, 64.9% including the validation set) is published distinctly — see the JSON below. We never present backtest numbers as verified predictions.
