Amazon Mechanical Turk stops accepting new customers as AI overtakes crowdsourcing platform

Amazon will stop accepting new customers for Mechanical Turk

These may be the last days of Amazon's Mechanical Turk. An announcement on the Mechanical Turk website says that on July 30, 2026, the crowdsourcing service will close to new customers. Amazon Web Services says the decision was made after "careful consideration," adding, "Existing customers can continue to use the service as normal. AWS continues to invest in security and availability improvements for Mechanical Turk, but we do not plan to introduce new features." In other words, Amazon isn't completely pulling the plug, but the service is very much on life support. First launched in 2005, Mechanical Turk was a marketplace where people were paid tiny amounts to perform simple tasks that resisted full automation -- things like completing CAPTCHA challenges or identifying the basic sentiment in a sentence. In its heyday, the service was at the center of debates around the ethics of crowdsourced labor, and it even played a small role in the early stages of the Facebook-Cambridge Analytica scandal. Beginning in 2018, Amazon also began billing it as a way for companies to annotate data to train neural networks as part of its SageMaker AI service. Less overtly, Mechanical Turk has also been described as the hidden enabler for companies taking a fake-it-till-you-make-it approach to AI, where products marketed as Ai are actually being performed by the Mechanical Turk workforce -- all the more fitting since the original Mechanical Turk was itself a hoax, with a hidden human chess player pretending to be a chess-playing machine Over time, the relationship between Mechanical Turk and AI models grew even more complicated. In a snake-eating-its-own-tail irony, a 2023 analysis found that between 33% and 46% of workers on the platform were using large language models to complete their tasks, raising questions about the reliability of data annotated on the platform and also about whether humans needed to be in the loop at all. This week, after Amazon's decision became public, one Reddit user suggested the platform died "years ago," with workers and researchers abandoning it due to bots and fraud. The user predicted, "Someone at Amazon is going to decide keeping the Mturk servers running is a waste of time and resources and pull the plug entirely."

Amazon's 'Artificial Artificial Intelligence' Is Being Eaten by AI

In the late eighteenth century, Hungarian inventor Wolfgang von Kempelen constructed what many people living at the time were duped into believing was the first truly intelligent machine: an ornate wooden chest, presided over by a magisterial wooden statue of a turbaned man -- a "Turk" -- that could move around the pieces of a chessboard as if by magic and win game after game against actual, human chess players. It was eventually revealed to be a hoax: A chess master would sit inside the box and control the game via an array of levers. The phrase "mechanical Turk" has since then become shorthand to describe instances in which a supposedly intelligent machine is actually an illusion, powered beneath the hood by human intelligence. It was a fitting name, therefore, for the first mainstream website that paid gig workers to complete menial digital tasks that weren't yet amenable to automation, such as transcribing audio files, identifying objects featured in satellite images, and verifying restaurant contact information. Launched by Amazon in 2005 and colloquially known as "MTurk," Mechanical Turk pays workers tiny amounts -- anywhere from one cent to a handful of dollars -- for completing a particular "human intelligence task," or HIT, as they're known. It also paved the way to later freelance sites like Fiverr and Upwork. Amazon founder Jeff Bezos has described Mechanical Turk as "artificial artificial intelligence." Since its launch, however, actual artificial intelligence has rapidly been catching up. Just as chess-playing algorithms like IBM's Deep Blue would eventually outperform human chess masters, modern AI systems are able to perform many of the tasks found on Mechanical Turk much more efficiently (and cheaply) than humans. It's little wonder then that Amazon appears to be in the early stages of retiring its 21-year-old service. On June 30, Amazon added an inconspicuous notice to the MTurk website: "Amazon Mechanical Turk will be closed to new customers, effective July 30, 2026," the company wrote. "Existing users will not be impacted by this change." In another announcement within the developer guide for SageMaker AI, Amazon Web Services' AI-building platform, AWS added that it "continues to invest in security and availability improvements for Mechanical Turk, but we do not plan to introduce new features." In other words, it appears that active MTurkers will be able to continue using the platform after the July 30 cutoff date. But given the rapid pace of evolution of AI-driven automation, it's likely that the number of tasks found on the platform -- and therefore its potential profitability for gig workers -- will dwindle. Amazon didn't immediately respond to a request for comment to elaborate on the platform's future for current users. Academic researchers who once relied on MTurk to conduct surveys have been abandoning the platform in droves in recent years, in part because of the growing presence of AI bots posing as human participants. The news that Amazon is closing the gates to new MTurk users was met by some people online with a mix of misty-eyed nostalgia and acceptance of the inevitable. "Personally, this is a bittersweet ending," one Redditor wrote last week. "MTurk helped me get started on online gig work, so I'm grateful for it just for that... It's like seeing an old friend well past their expiration date finally getting put to rest."

Amazon closes Mechanical Turk to new customers in July

Amazon's Mechanical Turk will close to new customers on July 30, 2026, following a decision made after "careful consideration," according to Amazon Web Services (AWS). Existing customers can continue to use the service without interruption, but AWS noted no new features will be introduced. Mechanical Turk, launched in 2005, served as a marketplace for simple tasks that resisted full automation, including completing CAPTCHA challenges and sentiment analysis. At its peak, the platform was central to ethical debates surrounding crowdsourced labor and was linked to the early stages of the Facebook-Cambridge Analytica scandal. In 2018, Amazon promoted Mechanical Turk as a tool for companies seeking to annotate data for training neural networks through its SageMaker AI service. The service has been described as enabling businesses to present their AI products as fully automated, despite their reliance on human workers. A 2023 analysis indicated that between 33% and 46% of Mechanical Turk workers leveraged large language models for their tasks. This raises concerns about the reliability of data annotated on the platform and the necessity of human labor. Amid the announcement of the service's future, a Reddit user remarked that Mechanical Turk had effectively ceased to function "years ago," attributing its decline to bots and fraud. The user predicted Amazon may ultimately decide to shut down the platform entirely.
