ChatGPT starts blocking direct requests to copy an author's style

OpenAI has updated ChatGPT to refuse prompts that ask it to copy or closely mimic a specific author’s writing style.

The move aligns ChatGPT with other AI systems that block style-imitation requests, reflecting rising concerns about copyright and ethical use.

The change may reduce legal and reputational risk for OpenAI and authors, but it also frustrates users who relied on author-specific outputs.
