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.

  • The jamba-1.5-large model from ai21-labs has a shrunk composite score of 34.5 and a raw composite score of 26.7, with scores covering 6 of 27 axes.

  • Over the past 180 days, jamba-1.5-large from ai21-labs has a standing of 34.5, compared with a cohort median standing of 37.7 across a cohort of 126 models.

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 →
