Theory-Grounded Evaluation Exposes the Authorship Gap in LLM Personalization

Yash Ganpat Sawant · 2026

Stylistic personalization - making LLMs write in a specific individual's style, rather than merely adapting to task preferences - lacks evaluation grounded in authorship science. We show that groundin…
