JUICE coordinates image and text generation by updating both streams from their current states, using a flow-matching Transformer over continuous features from frozen pretrained encoders. In maze-adapted SigLIP2, coupled sampling achieved 93.7% joint success versus 54.6% for independent sampling at 16 backbone calls. On synthetic mazes, image-first reached 95.2% and significantly outperformed coupled sampling, supporting coordination, not universal gains.
