Rupert Murdoch's Dow Jones and New York Post sue AI firm for 'illegal copying'

"This suit is brought by news publishers who seek redress for Perplexity's brazen scheme to compete for readers while simultaneously freeriding on the valuable content the publishers produce," according to the lawsuit filed in the southern district of New York by the Wall Street Journal parent Dow Jones and the New York Post. Perplexity did not immediately respond to emails from Reuters seeking comment. The AI company is among the leading startups attempting to uproot the search engine market dominated by Alphabet's Google. It assembles information from webpages it deems to be authoritative, then provides a summary directly within Perplexity's own tool. Perplexity uses a variety of large language models (LLMs) to generate its summaries, from OpenAI to Meta's open-source model Llama.
