A study by researchers from the Swiss Federal Institute of Technology (EPFL) has found that between 33% and 46% of workers paid to train AI models on platforms such as Mechanical Turk may be outsourcing the work to AI themselves. They used an AI model to assess whether those hired to summarise extracts from medical research papers had used AI models to do so. The percentage is likely to rise as AI systems such as OpenAI’s ChatGPT become more powerful and accessible. Crowdsourcing platforms will remain viable, however, it underlines the need for new ways to check whether data has been created by humans or AI.
