Researchers have developed VISTA, a model-agnostic technique for visualizing token importance in large language models without increasing computational cost. This method uses perturbation strategies and a three-matrix framework to assess how each token affects model predictions across semantic direction, intensity, and individual dimensions. Developers can now better understand AI systems' decision-making processes, enhancing transparency and trust in generative models.
