How much do AI training and data annotation jobs typically pay?

Considering signing up for one of these platforms. What's a realistic hourly rate to expect, and does it vary a lot?

It varies quite a bit by platform, task type, and your background. General, entry-level annotation and evaluation tasks commonly pay somewhere in the roughly $15-25/hour range. Specialized domain work — things that need a legal, medical, financial, or coding background — tends to pay noticeably more, sometimes $40-60+/hour, because the platforms need people who can actually judge whether a specialized answer is correct. Translation/localization-style tasks on these platforms are often priced per word or per project instead of hourly. Keep in mind these are contractor gigs, not salaried jobs: pay isn't guaranteed, hours fluctuate with task availability, and there's typically an unpaid application/qualification test before you get access to paid work at all. Treat any of these numbers as a ballpark rather than a promise — actual take-home varies a lot by how much task volume is available at a given time.
