Autoregressive Visual Generation Needs a Prologue

Bowen Zheng, Colin Zhang, Guang Yang, Tianyang Hu, Weijian Luo

Prepending a small set of prologue tokens trained only on AR loss decouples generation from reconstruction in autoregressive image models.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On ImageNet 256x256, Prologue-Base reduces gFID from 21.01 to 10.75 without classifier-free guidance while keeping reconstruction almost unchanged; Prologue-Large reaches a competitive rFID of 0.99 and gFID of 1.46 using a standard AR model without auxiliary semantic supervision.

C2weakest assumption

The assumption that training prologue tokens exclusively with AR CE loss will not interfere with the visual tokens' reconstruction quality and that the ELBO formalization supports the decoupled optimization.

C3one line summary

Prologue introduces dedicated prologue tokens to decouple generation and reconstruction in AR visual models, significantly improving generation FID scores on ImageNet while maintaining reconstruction quality.
