Agibot A2 vs Kepler Forerunner K2
Both humanoids read on the same 8 axes and 40 sub-axes, using the published Index scores. Every difference below carries the public evidence behind it, and sub-axes with no public evidence count as 0 rather than being skipped.
Overall standing
Capability score · 0–5 over 40 sub-axesThe short answer
Agibot A2 scores 0.23 higher than Kepler Forerunner K2, but that lead rests mostly on vendor claims and demos.
Only 12% of Agibot A2's score is carried by independently verified material — the rest is claimed or shown in demos. Kepler Forerunner K2 has more unscored ground than the gap between them, so this could change next month.

What would change it
7 sub-axes on the trailing side have no public evidence yet. If all of them scored full marks they would be worth 0.88 — against a gap of 0.23.

- Learning · Sim to realup to +0.125

There is more unscored ground than there is gap, so this result could turn over after the next research month.

Each wheel has 40 spokes — five per axis. A longer spoke is a higher score, and the dashed rings mark 1 to 4. Hover or tab onto any spoke to read the axis, the sub-axis and the exact value. A missing spoke means there is no public evidence for that sub-axis yet, which is not the same as scoring zero. The faint outline on each wheel is the other humanoid, drawn on the same scale.

What this comparison cannot settle
- Neither humanoid has a public read on 7 of the 40 sub-axes, so those cannot be compared at all.
- 14 sub-axes are read on only one side. A one-sided cell is undecided, not a zero for the silent side.
- Most of Agibot A2's score rests on vendor statements and demo footage rather than independently verified material (12% carried by verified evidence).
- Most of Kepler Forerunner K2's score rests on vendor statements and demo footage rather than independently verified material (5% carried by verified evidence).
- Demonstrations happen in different environments and product revisions are not always equivalent, so like-for-like uptime and throughput figures do not exist for most of the field.
