Amazon Discontinues Mechanical Turk After Nearly Two Decades of Crowdsourced Labor
Amazon is shutting down Mechanical Turk, the crowdsourcing platform it launched in 2005 that enabled companies to delegate small digital tasks to a global workforce of human contractors. The service, which Amazon co-founder Jeff Bezos famously described as "artificial artificial intelligence," became a foundational tool for data labeling, content moderation, and research surveys throughout the AI and machine learning boom.
Mechanical Turk operated on a marketplace model where requesters posted Human Intelligence Tasks (HITs) and workers could complete them for small payments. The platform played a significant role in the early development of machine learning datasets, with workers annotating images, transcribing audio, and categorizing data at scale. Researchers and startups widely used it as a cost-effective way to obtain labeled training data for AI models.
The shutdown marks the end of an era for crowdsourced labor platforms. While Mechanical Turk faced criticism over low pay and inconsistent quality, it established the gig-economy model for digital task work that later evolved into more sophisticated data annotation services used by major AI companies today.
Workers and requesters have been notified of the transition timeline, though specific dates for the final shutdown have not been publicly disclosed.
