When Scene Text Hijacks the Scene: Uncovering, Exploiting, and Mitigating Rendered-Text Semantic Leakage in Image Generation Models

Feifei Li, Runjie Wang, Xiaohan Zhang وآخرون · 2026

The reliability and accountability of image generative models (IGMs) are essential for building responsible and trustworthy AI systems. Recent IGMs, such as Nano Banana and GPT-Image, now support complex instruction following, realistic image synthesis, and controllable scene-text rendering. As these capabilities expan …

Reliability Testing of Medical Model Performance under Distributed Deployment

Yifei Wang, Xiaohan Zhang, Youtao Ding وآخرون · 2026

Distributed inference has become an indispensable part of deploying medical models under practical latency, memory, and throughput constraints. Although modern frameworks improve serving efficiency through tensor parallelism, mixed precision, kernel fusion, and multi-device communication, they are generally assumed to …

Test-Time Spatial Reasoning for Robot Manipulation Using Generative Real-to-Sim

Ivan Kapelyukh, Yafei Hu, Ran Gong وآخرون · 2026

Spatial reasoning is fundamental to general robot intelligence, as it enables robots to complete long-horizon tasks involving multi-object interaction. We introduce Simify, a training-free, test-time framework that performs explicit spatial reasoning via massively parallel physics simulation. From a single RGB-D image …
