Oct 15 (Reuters) - The New York Times ( NYT ) has sent

generative AI startup Perplexity a "cease and desist" notice

demanding the company stop using its content, the Wall Street

Journal reported on Tuesday.

The letter from the news publisher said the way Perplexity

was using its content, including to create summaries and other

types of output, violates its rights under copyright law, the

report said.

Perplexity and New York Times ( NYT ) did not immediately respond to

Reuters' requests for comment.

NYT is also tussling with ChatGPT maker OpenAI, which it had

sued late last year, accusing the firm of using millions of its

newspaper articles without permission to train its AI chatbot.
