In a three-storey facility in Noida, 19-year-olds fresh out of school spend eight hours a day teaching artificial intelligence how to see. They label pedestrians in traffic footage so self-driving cars stop in San Francisco.
They tag organs and surgical tools in medical footage so AI-powered diagnostics work in American hospitals. They rate big LLM answers for tone and accuracy so the chatbot sounds intelligent to its users.
