Amazon retires Mechanical Turk after 18 years of crowdsourcing labor
Amazon Web Services will stop onboarding new customers to Mechanical Turk starting July 30, 2026, marking the end of an 18-year chapter for one of the earliest large-scale crowdsourcing platforms. The service, often called the original “artificial artificial intelligence,” has long relied on human workers to complete small, repetitive tasks that remain difficult for machines—from image tagging to data annotation—before automated systems can take over.
A platform ahead of its time
Launched in 2005, Mechanical Turk pioneered the idea that many tasks could be outsourced to a distributed workforce rather than handled in-house or by algorithms. Its model inspired countless AI projects that depend on labeled datasets, yet it also highlighted the ethical and labor challenges inherent in crowdsourced work. Over time, the rise of more sophisticated AI tools and in-house labeling teams has gradually reduced the platform’s central role in research and industry pipelines.
What comes next for microtask labor
Existing customers will continue to use the platform until August 30, 2028, giving teams time to migrate workflows to newer alternatives. AWS has not announced a direct replacement, but the shutdown underscores a broader shift toward integrated, automated solutions that combine AI with curated human oversight. For researchers and businesses still relying on Mechanical Turk, the deadline offers a clear window to evaluate alternative platforms or build custom annotation workflows before the service is fully retired.
