The lawsuit, which was filed Thursday, claims that the AI company unlawfully crawls, scrapes, copies, and distributes CNN's content from CNN Digital Platforms and third-party platforms. It also accuses the AI tools of reproducing verbatim copies of its articles, including paywalled stories, in query responses to users. Perplexity's AI tools allegedly have incorrectly attributed hallucinated content to CNN, which the company says in the suit violates its trademark. CNN's lawsuit stands for the proposition that Perplexity, a company valued at tens of billions of dollars, should not be able to steal from entities that create the original content Perplexity exploits, a CNN spokesperson said in a statement to the outlet. The public rely on high quality news journalism reported by human beings to understand their world, which is frequently dangerous and expensive to produce.

Condé Nast, the media giant that owns The New Yorker, Vogue and Wired, has sent a cease-and-desist letter to AI-powered search startup Perplexity, according to The Information. The letter, sent on Monday, demanded Perplexity stop using content from Condé Nast publications in its AI-generated responses and accused the startup of plagiarism. It comes a month after Forbes took similar action. Condé Nast CEO Roger Lynch has warned "many" media companies could face financial ruin in the time it would take for litigation against generative AI companies to conclude. Lynch has called upon Congress to take "immediate action."
