Figure 03 vs Fourier GR-2

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 public record is still thin on at least one side of this pair, so treat the ordering as provisional rather than settled.

The short answer

Figure 03 scores 0.55 higher than Fourier GR-2, but that lead rests mostly on vendor claims and demos.

Only 7% of Figure 03's score is carried by independently verified material — the rest is claimed or shown in demos. Fourier GR-2 has more unscored ground than the gap between them, so this could change next month.

What would change it

14 sub-axes on the trailing side have no public evidence yet. If all of them scored full marks they would be worth 1.75 — against a gap of 0.55.

Perception · Semantic world modelup to +0.125
Autonomy · Instruction followingup to +0.125

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

How much we know

48%of sub-axes covered

We have public evidence for 48% of the 40 sub-axes across these two. Treat this as an early read.

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.

Figure 03 scores higher on Deployment and Manipulation — 1.13 against 0.80 for Fourier GR-2.

Running without a human in the loop

What this comparison cannot settle

Neither humanoid has a public read on 12 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.
Public evidence covers 48% of the sub-axes across the two. Treat the overall ordering as an early read.
Most of Figure 03's score rests on vendor statements and demo footage rather than independently verified material (7% carried by verified evidence).
Most of Fourier GR-2's score rests on vendor statements and demo footage rather than independently verified material (10% 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.
