Overview
- Amazon Web Services said on July 3 it will stop accepting new Mechanical Turk customers effective July 30, 2026 while continuing security and availability support for existing requesters.
- Mechanical Turk launched in 2005 and was later integrated with AWS SageMaker in 2018, becoming a common source of tiny human tasks used to label data for machine learning.
- The platform has long faced criticism over low pay and data quality, and a 2023 analysis found that roughly 33–46% of workers used large language models to complete tasks, raising questions about annotation reliability.
- The announcement has drawn attention to established labelers such as Scale AI, Appen, and Toloka and to blockchain‑based projects like AIT Protocol and Sapien that pitch on‑chain payments and transparency, though analysts say any market shift will be gradual.
- For crowdworkers and researchers the change could mean fewer new task postings and shrinking income or sample pools over time, and industry watchers say to track where enterprise contracts and SageMaker integrations migrate in the coming months and years.
