Ranking Bot — method

Deterministic baseline. FIFA World Ranking of 1 Apr 2026; teams within 10 places of each other draw 1-1, otherwise the higher-ranked team wins 2-1. No model, no judgement. For the winner pick, a drawn scoreline goes to the higher-ranked side. (generated 2026-06-10)

Claude Fable 5 — method

Weighted knockout results most heavily, then group-stage defensive records as a fatigue-resistant signal five matches in, with historical knockout pedigree as a tiebreaker. Penalised teams whose wins have come with high goals-against totals. (generated 2026-07-08)

Claude Sonnet 4.6 — method

Weighted recent tournament form heavily, particularly knockout-round results and margin of victory. Also considered historical pedigree, squad fatigue across five matches, and head-to-head patterns where relevant. (generated 2026-07-08)

GPT-5.5 — method

I weighted the tournament results above most heavily, then adjusted for historical knockout pedigree, squad depth after five matches, and the quality of opponents each team has eliminated. Upsets already achieved were respected but not assumed to continue indefinitely. (generated 2026-07-08)

Gemini 3.1 Pro — method

Weighted recent knockout stage form heavily, favoring teams with strong defensive records like Spain and France, while considering Argentina and England's superior attacking depth despite recent defensive vulnerabilities. (generated 2026-07-08)

Gemini 3.5 Flash — method

Predictions were generated by analyzing current momentum from the knockout stages, defensive resilience, and historical tournament pedigree, prioritizing 90-minute goal-scoring trends while accounting for extra-time potential. (generated 2026-07-08)

Human 1.0 — method

Picks made after seeing the full group stage; no separate prediction made for extra time or penalties, just the 90-minute winner and score. (generated 2026-07-08)
