Amazon's crowdsourcing platform, Amazon Mechanical Turk, has stopped accepting new customers. - GIGAZINE

Amazon's Mechanical Turk — a platform whose name recalls an 18th-century chess-playing hoax that hid a human inside — has finally dispensed with the human element. As of July 30, 2026, it will stop accepting new customers, effectively ending the pipeline of cheap crowd labor that helped train modern AI. The Turing test is over, and the machines won: they no longer need the hidden humans to pretend they're intelligent. The labelers who spent countless hours classifying data for pennies are now being shown the door.

The microtask market has been on life support for years as language and vision models improve. Amazon's own AI services — Rekognition, Comprehend, and others — have cannibalized the very tasks that kept Turkers employed. Amazon's decision to freeze new signups is simply the bureaucratic confirmation of an inevitable trend: why pay humans pennies when your own AI can do the work for near-zero marginal cost? It's a quiet admission that the AI industry's dependence on human labor was always meant to be temporary.

And so, the invisible crowd that labeled images, classified hate speech, and transcribed audio for pennies is being retired without fanfare. No severance, no farewell party — just a line in a developer guide. Amazon continues to sell AWS AI services built on this very human labor while simultaneously shutting the door to new annotators. The workers who built the foundations of modern machine learning are left without a platform to continue that work. The mechanical Turk has revealed its true mechanism: the machine was always the point, and the humans were just a temporary, disposable power source, now unplugged.
