Amazon to shut down Mechanical Turk, the crowdsourcing platform that powered ImageNet
量子位 · wechat · 2026-08-28
Amazon announced that its crowdsourcing platform, Mechanical Turk (MTurk), will shut down on September 30. Launched 21 years ago, MTurk once hosted over 500,000 global workers performing micro-tasks (HITs) like image classification and transcription.
Historical Impact
- Powered ImageNet: MTurk was essential for building the ImageNet dataset. Fei-Fei Li's team used the platform to distribute the screening of hundreds of millions of images to workers worldwide.
- Deep Learning Catalyst: ImageNet enabled the 2012 AlexNet breakthrough, which kickstarted the deep learning revolution and established the reputations of Geoffrey Hinton, Ilya Sutskever, and Fei-Fei Li.
Reasons for Shutdown
- Technical Obsolescence: Tasks that once required human labor, such as basic image classification, are now easily handled by AI models.
- Evolving Demands: Modern frontier models require expert-level data (e.g., RLHF, complex reasoning). Professional platforms like ScaleAI are replacing MTurk's low-skill crowdsourcing model.
- Self-Disruption: Studies show many MTurk workers now use AI models to complete text tasks, undermining the value of "human judgment."
