Researchers have developed VISTA, a novel test-time alignment framework designed to improve compositional accuracy in visual autoregressive (VAR) models. Unlike previous methods for diffusion models, VISTA is specifically engineered for the discrete, multi-resolution sampling process of VAR generation. It optimizes intermediate representations within a frozen transformer to enhance attribute binding and spatial relations without altering model parameters or requiring additional training. VISTA has demonstrated significant improvements in compositional categories, boosting scores by up to 20% on a 2B backbone model and preserving image quality, even enabling a smaller model to outperform a larger one.
