AI training platforms ask for a tax form before your first payout. Whether it is a W-9 or a W-8BEN depends on one thing, whether the IRS treats you as a US person. What each form is for, who fills in which, and what the W-8BEN asks for, from the IRS pages.
A growing share of AI training jobs ask for more than your time: a clone of your voice, your personal Gmail and calendar, recordings of your screen, or first-person video of your home. What current listings actually ask for, what they leave unsaid, and the questions to settle before you connect or record anything.
Every listing shows its pay and who it is open to.
