Open-Ended CT Volume Segmentation with Weak Supervision from Language

Sanjay Subramanian, Junwei Yu, Zirui Wang +5

We introduce a method for training a text-conditioned segmentation model for CT scans, which combines voxel-level supervision with coarse but scalable slice-level supervision from…

ThreadWeaver: Adaptive Threading for Efficient Parallel Reasoning in Language Models

Long Lian, Sida Wang, Felix Juefei-Xu +7

Scaling inference-time computation has enabled Large Language Models (LLMs) to achieve strong reasoning performance, but their inherently sequential decoding incurs substantial lat…

Stateful Visual Encoders for Vision-Language Models

Zirui Wang, Junwei Yu, Adam Yala +3

Vision-language models (VLMs) are increasingly used in multi-image, multi-turn agentic settings where decisions depend on visual changes. However, in existing open-weight VLMs, vis…

Pillar-0: A New Frontier for Radiology Foundation Models

Kumar Krishna Agrawal, Longchao Liu, Long Lian +11

Radiology plays an integral role in modern medicine, yet rising imaging volumes have far outpaced workforce growth. Foundation models offer a path toward assisting with the full sp…
