New Report Reveals ChatGPT Implemented Unusual Content Restrictions
Recently, OpenAI implemented an unannounced update to ChatGPT’s operating guidelines that introduces a new restriction: the model will no longer be able to fully replicate the distinctive writing styles of living authors. This change was incorporated into the system’s functional parameters without any public announcement, with the aim of further minimizing potential copyright-related issues.
Tests have confirmed that this limitation is already in place. When users ask ChatGPT to mimic the opening of a story based on a contemporary author, adapt classic works, or generate content in a specific author’s style, the system will refuse to fully reproduce that author’s unique approach and linguistic rhythm. For instance, requests to write an opening in Stephen King’s style, rewrite “The Odyssey” using that horror writer’s tone, or start writing in Amy Tan’s voice will no longer receive a response. Instead, the model will use general creative elements such as themes, narrative structure, and atmospheric creation to produce original content.

Interestingly, this restriction only applies to living authors. Users can still request imitations or style reproductions of writers who have passed away, such as Charles Dickens, Ernest Hemingway, and William Shakespeare, and ChatGPT will respond as usual.
The legal basis for this policy is straightforward. Under current U.S. copyright laws, protection applies only to the specific textual expressions created by authors, not to abstract writing styles. Industry experts suggest that OpenAI introduced this restriction primarily to reduce potential copyright disputes and lower the company’s operational risks — serving as a defensive measure in addressing copyright issues related to literary content generated by AI.
As generative AI becomes increasingly capable of mimicking the voice and style of specific individuals, questions regarding ownership of replicated creative styles and secondary works based on existing content have long been a focal point for both the global AI industry and the literary community. While relevant industry standards and legal frameworks are still being developed, ChatGPT’s new restriction represents another step in this ongoing effort to address these complexities.
