Percentiles are the model's standing within each board's own population. Axes marked "not benchmarked" have no published result for this model — that is an absence of data, not a low score.
grok-4.20-0309-reasoning stands at 54.7 (raw mean 59.4) — measured on 3 of 27 axes.
grok-4.20-0309-reasoning ranks between #68 and #287 across 4 built-in weightings — best under "Reasoning", worst under "All sources".
Every claim is a computed fact from the current board data, phrased by a low-temperature model call and rejected by a validation gate if any number is not in the source row. How the leaderboards work →
