Janus: Decoupling Visual Encoding for Unified Multimodal Understanding and Generation

Chengyue Wu, Chong Ruan, Ping Luo, Wen Liu, Xiaokang Chen, Xingchao Liu, Xingkai Yu, Yiyang Ma, Zhenda Xie, Zhiyu Wu, Zizheng Pan

Decoupling the visual encoder into separate pathways lets a single transformer handle both multimodal understanding and generation without performance trade-offs.

✓ Portable graph bundle live · download bundle · merged state

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

Experiments show that Janus surpasses previous unified model and matches or exceeds the performance of task-specific models.

C2weakest assumption

That the conflict arising from differing information granularity in understanding versus generation is the main performance bottleneck and that decoupling the encoders will resolve it without introducing new integration problems in the shared transformer.

C3one line summary

Janus decouples visual encoding into task-specific pathways inside a single autoregressive transformer to unify multimodal understanding and generation while outperforming earlier unified models.
