The recent lawsuit filed by The Chicago Tribune against AI search engine Perplexity has raised concerns about copyright infringement in the digital age. The Tribune alleges that Perplexity has been using its content without permission, delivering verbatim summaries of Tribune articles through its Retrieval Augmented Generation (RAG) system.
According to the lawsuit, Perplexity’s lawyers initially denied using Tribune content for model training, claiming they only received non-verbatim factual summaries. However, the Tribune’s legal team argues that Perplexity’s RAG method is scraping and using the newspaper’s content without authorization. Additionally, the lawsuit alleges that Perplexity’s Comet browser is bypassing the Tribune’s paywall to provide detailed summaries of its articles.
This is not the first time media organizations have taken legal action against AI model makers for copyright infringement. The Tribune is part of a group of news publications that previously sued OpenAI and Microsoft over similar issues. While these lawsuits are ongoing, the Tribune’s case against Perplexity highlights the potential legal implications of using RAG technology without proper authorization.
Perplexity has not responded to the Tribune’s lawsuit or requests for comment. The AI search engine is also facing legal challenges from other companies, such as Reddit and Dow Jones. Amazon has even threatened legal action against Perplexity for AI browser shopping.
As the debate over intellectual property rights in the AI industry continues, it remains to be seen how the courts will address the use of RAG technology and its potential legal liabilities. In the meantime, media organizations and content creators are advised to protect their work and seek proper permissions before allowing AI models to use their content.
