• Condé Nast, the publishing company behind magazines like Vogue, Vanity Fair, and The New Yorker, has issued a cease and desist order to Perplexity AI, a startup that uses AI to generate content. Condé Nast claims that Perplexity AI's use of its trademarks and copyrighted content without permission is a violation of its intellectual property rights.

• Perplexity AI is a startup that uses large language models and other AI technologies to generate written content, including articles, essays, and stories. The company has been using Condé Nast's trademarks and copyrighted content as part of its training data, which Condé Nast alleges is unlawful.

• The cease and desist order demands that Perplexity AI immediately stop using Condé Nast's trademarks and copyrighted content, and threatens legal action if the company does not comply. This highlights the ongoing tensions between traditional media companies and AI startups that are using their content without permission.
