“While we believe in the ethical and responsible use and development of AI, we firmly object to Perplexity’s unlicensed use of our content to develop and promote their products,” NYT spokesperson Graham James said in a statement.

The NYT is seeking damages, injunctive relief and other equitable remedies to prevent Perplexity from continuing its alleged unauthorized use of content.

Perplexity was also sued by the Chicago Tribune on Thursday.
