Engineering is 44.7% at OpenAI, 41.6% at Anthropic, and 40.3% at xAI. The role mix sits in a 9,421-profile US sample: OpenAI 5,313, Anthropic 2,612, and xAI 1,496. The engineering band is 40.3% to 44.7%, so the visible difference is not a large engineering gap. The parent map treats the non-engineering mix as the sharper contrast. These are US public-profile counts, not official headcount, and they are not a global census.

FAQ
Is 9,421 global headcount?
No. It is a US public-profile sample of the three companies.
Are the company counts additive to 9,421?
The parent map states the US sample as 9,421 and the company counts as 5,313, 2,612, and 1,496.
Is engineering the differentiator?
The published band is only 40.3% to 44.7%. The parent map points to the non-engineering mix for the sharper contrast.
Is xAI’s engineering share the Human Data share?
No. Engineering at xAI is 40.3%. Human Data is a different question page.
