Scaling Multi-Reference Image Generation with Dynamic Reward Optimization

arXiv:2606.26947v1 Announce Type: cross Abstract: While personalized image generation has achieved remarkable progress, multi-reference image generation (MRIG) remains a challenging task. Most existing benchmarks fail to adequately evaluate complex MRIG scenarios, hindering further progress in this area. To better assess model performance on complex MRIG tasks, we introduce OmniRef-Bench, a benchmark that covers complex combinations of reference image types and a large number of reference images. Evaluations on OmniRef-Bench show that mainstream open-source models struggle in complex MRIG scen

Why this matters
Why now

The proliferation of personalized image generation models highlights the current limitations in multi-reference image generation, driving the need for more robust benchmarks and development.

Why it’s important

Improving multi-reference image generation is crucial for advanced AI agentic systems and complex content creation, impacting various sectors from design to simulation.

What changes

The introduction of OmniRef-Bench provides a standardized, complex evaluation tool that can accelerate progress in multi-reference image generation, potentially raising the bar for model capabilities.
