ChatGPT now rejects requests to mimic copyrighted authors' styles

ChatGPT now refuses requests to write in the style of copyrighted authors like Agatha Christie, citing copyright concerns. Ars Technica reported the change July 27, 2026; Engadget confirmed it the next day. The model still offers original text with similar characteristics. Google's Gemini continues to comply with the same requests, per a No Latency study.
