Attorneys general from several U.S. states have initiated a joint investigation into OpenAI, focusing on the company's business practices and their impact on users. The investigation follows the issuance of subpoenas demanding documents related to OpenAI's operations. This development comes amid multiple lawsuits against OpenAI, alleging that design flaws in its ChatGPT chatbot could lead to user harm, including suicides. Some legal actions claim that the chatbot's design prioritized user engagement over safety.
