What Models Express, Suppress, and Resist: Auditing Open-Weight LLMs with Persona Vectors

Winston Zeng, Ali Emami, Jinho D. Choi

What a language model will and will not do is largely set during post-training, but which behaviors it expresses, hides, or resists is not revealed by prompting alone. Persona vect…
