Mental health service used an AI chatbot without telling people first

A mental health service that allows people to receive encouraging words of support and advice from others tested AI-generated responses without first notifying the recipients. Rob Morris, founder of the free mental health service Koko, outlined in a series of Twitter posts how the firm tested using a chatbot to help provide mental health support to about 4000 people. The chatbots were powered by GPT-3, a publicly available AI built by San Francisco-based company OpenAI.
