🤖Amazon Closes Mechanical Turk to New Users in July 2026
Mechanical Turk's End Is Near: What Happens Next?
TL;DR
Amazon is closing its Mechanical Turk service to new customers in July 2026. Existing users can continue but no new features will be added. This move raises questions about the future of crowdsourced data annotation and the reliability of data from such platforms.
Amazon Web Services (AWS) announced it would close Amazon Mechanical Turk to new customer sign-ups starting July 30, 2026. Existing users can continue using the service as usual but won't see any new features or improvements. Launched in 2005, Mechanical Turk was a marketplace for simple tasks that resist full automation, like CAPTCHA challenges and sentiment analysis. However, its role has diminished with advancements in AI and concerns over data reliability and ethics. In 2018, AWS positioned it as an annotation tool for training neural networks via SageMaker. But by 2023, up to 46% of workers were using large language models to complete tasks, raising questions about the platform's value moving forward.
