Amazon's Mechanical Turk to stop accepting new customers
Amazon is halting new customer sign-ups for Mechanical Turk, its crowdsourcing marketplace for human-powered micro-tasks. The platform, once a pioneer for leveraging humans to handle tasks too difficult for automation, faces an uncertain future as AI alternatives emerge and demand wanes. The move signals a significant shift away from this model of human computation.
Background
Amazon Mechanical Turk (MTurk) is a crowdsourcing marketplace launched in 2005 where businesses ("requesters") pay workers ("Turkers") to perform small, repetitive tasks that computers struggle with — like labeling images, transcribing audio, or moderating content. These micro-tasks, known as HITs (Human Intelligence Tasks), have been widely used to train AI models and power data pipelines. Amazon announced it will stop accepting new requesters (the customers who post tasks) on the platform, effectively freezing its business to existing users. This signals the slow wind-down of one of the oldest and most controversial gig-economy platforms. Critics have long condemned MTurk for paying extremely low wages (often pennies per task), lacking employment protections, and operating with opaque policies. The decision comes as large language models and generative AI reduce the need for human data labelers, making MTurk's original value proposition obsolete. The move also reflects broader pressure on Amazon from labor advocates and regulators.
