Activation steering lets users alter LLM personality without fine-tuning

Researchers have developed a technique called activation steering, which allows users to alter a large language model's behavior and personality at runtime without requiring traditional fine-tuning. This method involves identifying specific directions in the model's internal vector representations that correspond to abstract concepts like emotions or themes. By mathematically manipulating these vectors during the model's computation, users can influence its output, effectively steering its responses towards desired characteristics, such as an obsession with a particular topic.
