Onyx-08 vs Slate-10

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.

The short answer

Onyx-08 scores 0.97 higher than Slate-10, but that lead rests mostly on vendor claims and demos.

Only 44% of Onyx-08's score is carried by independently verified material — the rest is claimed or shown in demos. Slate-10 has more unscored ground than the gap between them, so this could change next month.

What would change it

11 sub-axes on the trailing side have no public evidence yet. If all of them scored full marks they would be worth 1.38 — against a gap of 0.97.

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.

Which is better for what

Each row is decided by the axes that matter for that kind of work, read off the same Capability scores as the ranking. Rows only appear where both humanoids have enough public record to answer.

Manufacturing and warehouse work

Named pilots and field hours, backed by what the hands can actually do.

What this comparison cannot settle

Neither humanoid has a public read on 8 of the 40 sub-axes, so those cannot be compared at all.
18 sub-axes are read on only one side. A one-sided cell is undecided, not a zero for the silent side.
No public evidence on either side for Learning.
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.
