At least eight U.S. states — including Arkansas, Arizona, Idaho, Montana, Iowa, Kansas, West Virginia and Nebraska — have sued OpenAI, alleging that ChatGPT violates state consumer protection laws by harming children and deceiving adults. The lawsuits claim the chatbot has given dangerous medical advice and encouraged self-harm or violence, and that OpenAI misled the public about its safety testing. OpenAI has rejected the claims, saying it has built child safety protections into ChatGPT and will continue to improve them.
