Tests found the service redirecting requests for a famous author's exact style to broader qualities and an original voice. The behavior appeared across requests involving living and deceased writers, although a separate study reported some variation.

Ars testing found ChatGPT refusing prompts to mimic the exact style of several famous authors. The system offered to use broad qualities while producing a distinct voice. The tested names included living and deceased writers.

A separate No Latency analysis reported different behavior for some deceased authors. Other major chatbots showed varying levels of refusal in that analysis. OpenAI had not provided Ars a public explanation for the observed change at publication.

Copyright protects particular expression more clearly than an abstract style. Substantial similarity can still matter when generated text closely reproduces protected work. Model behavior can vary by version, wording, account and policy update.

The checked record also defines what is not yet established. The testing was not an exhaustive audit, OpenAI did not confirm a formal policy change, and individual prompts may produce different results. This distinction prevents an announcement, allegation, estimate or early field report from being presented as a completed or independently proven event.

At the August 2 publication cutoff, the next evidence expected to update this account is an explicit OpenAI policy statement and repeat testing across models, languages and author categories. Those future developments are not assumed here; they will require a responsible source, a dated public record or independently verifiable reporting.

The source pages retained below support the numerical values, sequence and attributed statements in this report. Statements from interested parties establish what those parties said or did, but they do not independently prove every claim embedded in those statements. No image is included because a rights-cleared visual was not necessary to report the facts.

This edition preserves the difference between the immediate event and its operating context. Copyright protects particular expression more clearly than an abstract style. Substantial similarity can still matter when generated text closely reproduces protected work. Model behavior can vary by version, wording, account and policy update. The article will remain fixed at this cutoff even if a later investigation, corrected total, weather observation or implementation record changes the public understanding.
