Summary
DanceOPD (arXiv:2606.27377) is a paper by Wei Zhou, Xiongwei Zhu, and Zelin Xu proposing an on-policy generative field distillation framework for unified image generation. Modern image generation models are expected to combine multiple capabilities in a single model: text-to-image (T2I) synthesis, local editing, and global editing. These capabilities are rarely naturally aligned and often conflict with one another—for example, adding editing ability tends to degrade T2I performance, while global and local editing interfere with each other. Composing these capabilities has therefore become a central challenge in training image generation models. DanceOPD addresses this by ensuring each capability learns from the distribution of the model's own generations (on-policy learning), which avoids misalignment and capability conflicts. The framework offers a path toward training a single image generation model that unifies diverse tasks without mutual degradation.

Summary
Modern image generation demands a single model that unifies diverse capabilities, including text-to-image (T2I), local editing, and global editing. However, these capabilities are rarely naturally aligned and often conflict. For instance, editing tends to degrade T2I performance, while global and local editing interfere with each other. Consequently, effectively composing these capabilities has become a central challenge for image generation model training.
To tackle this, the authors introduce DanceOPD, an on-policy generative field distillation framework. The core idea is to ensure that each capability learns from the distribution of the model's own generated outputs (on-policy learning), rather than from off-policy data that may be misaligned with the model. This avoids misalignment and capability conflicts, enabling a unified model that handles T2I, local editing, and global editing without one task degrading another.
