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.
kimi-k2.5-instant stands at 60.7 (raw mean 65.2) — measured on 7 of 27 axes.
kimi-k2.5-instant stands at 60.7 versus a cohort median of 60.6 across 171 models released within 180 days — above the peer median.
kimi-k2.5-instant ranks between #84 and #354 across 6 built-in weightings — best under "Agentic", 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 →
