arXiv:2606.06735v1 Announce Type: new Abstract: Linear activation steering has gained popularity as a simple and empirically effective way to control language model behavior. More recently, spherical steering paradigms have been proposed to address limitations of additive interventions, often motivated by the assumption that hidden-state norm does not carry concept-relevant information. In this work, we revisit this assumption through a controlled empirical study designed to disentangle the roles of angular and radial components. We show that steering methods differ mainly in how they couple t
This research is emerging now as the field of large language models rapidly advances, necessitating deeper understanding and refined control mechanisms for their complex behaviors.
Understanding the fundamental mechanisms of activation steering can lead to more robust, controllable, and predictable AI, which is critical for trustworthy and impactful applications.
This work refines our understanding of how language models are controlled, moving beyond simplistic additive interventions to a more nuanced view that disentangles angular and radial components.
