ChatGPT stops imitating famous authors' writing styles

ChatGPT now refuses to write in the style of copyrighted authors like Agatha Christie, saying it cannot imitate her distinctive style. Ars Technica reported this on July 27, 2026; Engadget confirmed it the next day. The chatbot still offers original writing with similar qualities. Google's Gemini still does what users ask, according to a No Latency study.
