Researchers have developed a novel method for controlling Large Language Models (LLMs) by adapting principles from neurostimulation. This approach treats LLM steering as a feedback-control problem, where the model's internal state dictates the intervention, rather than relying on fixed, open-loop methods. The proposed $H_ ext{inf}$ controller enhances performance, particularly in out-of-distribution scenarios, by accounting for model uncertainties and linearization mismatches. Additionally, a new metric, robust steerability ($S_{ ext{rob}}$), is introduced to pre-assess a controller's tolerance to dynamic mismatches, showing task-specific structure and variation with model scale.
