Compare · 2026-07 cohort

Compare humanoids on Index scores.

Everything here uses the same numbers as the Index: one score across 8 axes and 40 sub-axes. For each difference we also show how much public evidence sits behind it. Where there is no evidence yet, we say so rather than scoring a zero.

Nothing selected yet

Pick two humanoids to compare.

You can also compare one humanoid against the cohort average or the cohort best. Both are worked out sub-axis by sub-axis from every published entry, not copied from any single robot.

LevelWide apart

Each cell is the Capability gap between the two. “Thin” marks a pair where one side has fewer than 20 of the 40 sub-axes on the public record — the page still opens, it just says plainly how little there is to compare.
