Amazon to close Mechanical Turk to new customers

Amazon Amazon.com, Inc. ↘ 0.35% will stop accepting new customers for its Mechanical Turk crowdsourcing platform on July 30, 2026, placing the 21-year-old service into maintenance mode as advances in AI automation erode the need for human microtask labor.

A Quiet Wind-Down

A banner now displayed on the MTurk homepage reads: "Amazon Mechanical Turk will be closed to new customers, effective July 30, 2026. Existing users will not be impacted by this change." AWS has added the service to its internal "Services in Maintenance" list, a designation the company uses for products it intends to wind down.theregister+1

According to TechCrunch, AWS described the decision as made after "careful consideration" and said it will continue investing in security and availability but does not plan to introduce new features. The Register reported that when contacted, Amazon confirmed the notice means Mechanical Turk will stop accepting jobs for SageMaker and all other tasks.letsdatascience+1

Existing requesters and workers can continue using the platform for now, though the move is widely interpreted as a precursor to full retirement.

From Microtasks to AI Labels — and Obsolescence

Launched in 2005, Mechanical Turk was designed to pay workers small amounts for tasks that computers could not easily perform, from image tagging to survey completion. The platform drew its name from an 18th-century chess-playing automaton that secretly hid a human operator inside.

In 2018, Amazon repositioned MTurk as a data-labeling tool integrated with SageMaker, its machine learning service. But the very AI systems that MTurk helped train have increasingly rendered its human workforce unnecessary. The MTurk site now directs machine learning users toward SageMaker Ground Truth and Ground Truth Plus, managed labeling services that use private or vendor workforces rather than an open marketplace.aiweekly+1

What Comes Next

The closure to new customers leaves current users in limbo. AWS has made no announcement about a final shutdown date, but the maintenance designation and feature freeze suggest the platform's days are numbered. For the academic researchers and AI companies that relied on MTurk as a cheap source of human intelligence tasks, the transition marks the end of a tool that shaped early machine learning development — and was itself made obsolete by the technology it helped create.geekhaus
