OpenAI ignored three warnings that a ChatGPT user was dangerous — including its own mass-casualty flag — while he stalked and harassed his ex-girlfriend, a new lawsuit alleges.

Evidence presented at the trial swayed the jury to the plaintiff's side, demonstrating that Meta understood how addictive its platforms could be among teens in particular and that it was actively researching the issue and using its findings to increase engagement among young users.

Encyclopedia Britannica and Merriam-Webster say that OpenAI violated the copyright of almost 100,000 articles by using them for LLM training.
