Outlier

Outlier is the largest single source of AI training work for English-speaking specialists. Operated by Scale AI, it routes projects from frontier labs to a vetted contractor pool.

Most contributors land between $15 and $40 an hour for general tasks; coding, math, and medical specialists routinely clear $50–80. Payment is reliable and weekly, but you should expect availability to ebb and flow as project budgets shift.

The biggest knock against Outlier is opacity: rubrics and project briefs can change mid-stream, and your scores influence what work you see next. Treat it as a serious side income rather than a guaranteed full-time engine.
