## Chicago Tribune Sues Perplexity Over Copyright Infringement
Chicago, IL – Tribune Publishing, parent company of the Chicago Tribune, has filed a lawsuit against artificial intelligence startup Perplexity AI, alleging widespread copyright infringement. The suit, filed in a federal court, accuses Perplexity of “systematic and unauthorized copying” of the Tribune’s journalistic content to train its AI models and generate answers without proper attribution or compensation.
The complaint states that Perplexity’s AI-powered search and summarization tools directly reproduce Tribune articles, often verbatim, effectively “freeriding” on the publisher’s significant investment in original journalism. This alleged practice deprives the Tribune of advertising revenue, subscription income, and control over its copyrighted material.
This action by Tribune Publishing marks another significant legal challenge for AI companies, following similar lawsuits from other major news organizations, including The New York Times, against firms like OpenAI and Microsoft. The burgeoning legal landscape highlights growing tensions between content creators and AI developers over the use of copyrighted material in training large language models and generating public-facing content.
The Tribune is seeking damages, an injunction to prevent further infringement, and a declaration that Perplexity’s actions are unlawful, emphasizing the critical need for fair compensation and respect for intellectual property in the age of artificial intelligence.
