In 2005, Jeff Bezos described Mechanical Turk as "artificial artificial intelligence": tasks computers couldn't yet solve, handled by humans behind an API. Twenty-one years later, real AI no longer needs that crutch — and Amazon is switching off the platform.
Amazon will shut down Mechanical Turk (MTurk) on September 30, 2026. The platform, launched in 2005, worked as a marketplace where companies posted micro-tasks — formally called "Human Intelligence Tasks" — ranging from data labeling and audio/video transcription to completing surveys. Amazon had already stopped accepting new clients as of July 2026, which was the first clear sign of the coming shutdown.
MTurk had been in quiet decline for years. Amazon invested less and less in improving the platform while a new generation of services specialized in AI data — Scale AI, Mercor, Prolific, among others — took its workers with better tools and better pay. The irony is complete: the platform that helped train the first generation of machine learning systems with cheap human labor becomes obsolete precisely because those same systems have now matured.
If your company still uses (or ever used) MTurk to generate training datasets, human model evaluation, or output validation, September is the hard deadline to migrate that workflow to another provider. More broadly, it's a clear market signal: AI data labeling has professionalized and specialized — it's no longer a generic micro-task job, it's its own provider category with domain expertise. For RAG or fine-tuning architectures that depend on curated datasets, it's worth checking whether your current labeling provider still meets the quality bar a 2026 model demands.
