CNN has sued AI search company Perplexity, alleging the firm unlawfully copied more than 10,000 CNN stories, videos, images, and other works to train and power its products, according to the complaint filed this week.
The network accused Perplexity of reproducing its content without permission or payment, using the material commercially to build tools that compete with the publishers that produced the underlying journalism.
CNN's suit is among the most specific in volume of alleged infringement filed against an AI company to date, placing a concrete count — 10,000-plus works — at the center of the claim.
Perplexity has faced similar copyright complaints from other news organisations and publishers in recent months and has previously disputed characterisations of its content-handling practices.
The case joins a growing docket of AI copyright litigation working through federal courts. A scheduling hearing is expected to set deadlines in the coming weeks.
