Card stats
Intelligence ▲ higher wins
Intelligence Index: a composite score from 10 hard evaluations covering reasoning, knowledge, coding, agents and science.
12.3
beats 16% of deck
Hallucination ▼ lower wins
Hallucination rate: of the questions a model gets wrong, how often it confidently makes up an answer instead of saying it doesn't know. Lower wins.
80 %
beats 21% of deck
Context ▲ higher wins
Context window: how many tokens of input the model can consider at once.
260K
