The AI trainer gig layer
Beneath every named AI role sits a contingent-labor layer: domain experts hired per-task to train, evaluate, and red-team models. Not employees, not headcount — a labor market parallel to the org chart. Mercor reports ~30,000 contractors at an average billed rate near $95/hr; Scale AI's Outlier runs a similar platform. Where the judgment, taste, and domain expertise that tunes today's models actually comes from.
