ChatGPT now refuses to imitate copyrighted authors' writing styles, citing copyright

ChatGPT now refuses requests to write in the style of copyrighted authors like Agatha Christie, telling users it "can't provide text that closely imitates her distinctive style." Ars Technica first reported the shift on July 27, 2026; Engadget independently confirmed it the next day. The model still offers original text with "those characteristics." Google's Gemini, per a No Latency study, still complies with the same requests.
