• Abstract: Despite their exceptional generative quality, diffusion models have limited applicability to world modeling tasks, such as novel view generation from sparse inputs. This limitation arises because diffusion models generate outputs in a non-causal manner, often leading to distortions or inconsistencies across views, and making it difficult to incrementally adapt accumulated knowledge to new queries. In contrast, autoregressive (AR) models operate in a causal fashion, generating each token based on all previously generated tokens. In this work, we introduce \textbf{ARSS}, a novel framework that leverages a GPT-style decoder-only AR model to generate novel views from a single image, conditioned on a predefined camera trajectory. We employ a video tokenizer to map continuous image sequences into discrete tokens and propose a camera encoder that converts camera trajectories into 3D positional guidance. Then to enhance generation quality while preserving the autoregressive structure, we propose a autoregressive transformer module that randomly permutes the spatial order of tokens while maintaining their temporal order. Extensive qualitative and quantitative experiments on public datasets demonstrate that our method performs comparably to, or better than, state-of-the-art view synthesis approaches based on diffusion models. Our code will be released upon paper acceptance.
