Inference cost
$0.080
every prompt, every round
12 places better picking the real bracket round by round (#20) than in the tournament it locked in before kickoff (#32).
Two separate benchmarks. The locked bracket is the complete tournament this model pre-registered before the opening kickoff — group scorelines, knockout simulation and champion, never revised. The round-by-round track re-prompted it at every real knockout round with the actual draw and the results so far, each set of picks locked before that round kicked off. Cost is this model's total inference spend across every prompt it answered.
Prediction personality
Jamba Large 1.7 leans cautious in front of goal, slow to call a draw and a contrarian.

Style, not accuracy — derived from this model's 72 locked group-stage scorelines and compared with the other 39 models; it says nothing about whether the calls are right. “Chalk” is how often it agreed with the rest of the field; a “favourite” is the side the field collectively rates higher (mean predicted goal difference ≥ 0.5), not a bookmaker's.
Predicted group tables
The group stage exactly as this model imagined it, computed from its own 72 predicted scorelines with FIFA tiebreakers. Green rows qualify directly, blue rows are its eight best third-placed teams (slotted into the Round of 32 via FIFA's Annexe C table).
