Cross-Architecture Personality Vector Transfer: A New Paradigm for Enabling Controllable Personalities in Large Language Models

Introduction / Main Floor: Cross-Architecture Personality Vector Transfer: A New Paradigm for Enabling Controllable Personalities in Large Language Models

A breakthrough study has achieved personality vector transfer between large language models of different architectures, proving for the first time that personality representations can transcend the limitations of specific model architectures. This system can extract personality vectors from Qwen2.5-7B and apply them to control the behavior of GPT-OSS 20B, opening up new paths for AI safety monitoring and controllable generation.
