HarnessRisk: A Lifecycle-Oriented Benchmark for Agent Harness Safety

Yajing Bai, Jinhao Duan, Jie Peng +4

Large language models are increasingly deployed through agent harnesses that manage tools, extensions, persistent state, permissions, and external actions. Existing safety benchmar…

Bifocal Diffusion Language Models: Asymmetric Bidirectional Context for Parallel Generation

Yuhang Chen, Xianfeng Wu, Jinhao Duan +11

Discrete diffusion language models (dLLMs) recover masked tokens in parallel, offering significant speedups over autoregressive (AR) generation. However, such promising frameworks…

ScalingAR: Scaling Confidence for Autoregressive Image Generation

Harold Haodong Chen, Xianfeng Wu, Wen-Jie Shu +4

Test-time strategies have shown remarkable success in improving large language models, but their application to next-token prediction (NTP) autoregressive (AR) image generation rem…

Timage: A Generative Text-in-Image Paradigm for Fine-Tuning Vision-Language Models

Yifeng Wu, Huimin Huang, Ruiluo Wu +5

Multimodal Large Language Models (MLLMs) often lose track of the right image regions during fine-grained spatial reasoning, because a textual query rarely carries any explicit geom…

Learning Latent Proxies for Controllable Single-Image Relighting

Haoze Zheng, Zihao Wang, Xianfeng Wu +5

Single-image relighting is highly under-constrained: small illumination changes can produce large, nonlinear variations in shading, shadows, and specularities, while geometry and m…

4DLangVGGT: 4D Language-Visual Geometry Grounded Transformer

Xianfeng Wu, Yajing Bai, Minghan Li +5

Constructing 4D language fields is crucial for embodied AI, augmented/virtual reality, and 4D scene understanding, as they provide enriched semantic representations of dynamic envi…
