WildDet3D: Scaling Promptable 3D Detection in the Wild

Weikai Huang, Jieyu Zhang, Sijun Li +15

Understanding objects in 3D from a single image is a cornerstone of spatial intelligence. A key step toward this goal is monocular 3D object detection--recovering the extent, locat…

You Only Judge Once: Multi-response Reward Modeling in a Single Forward Pass

Yinuo Yang, Zixian Ma, Manasi Ganti +2

We present a discriminative multimodal reward model that scores all candidate responses in a single forward pass. Conventional discriminative reward models evaluate each response i…

MolmoPoint: Better Pointing for VLMs with Grounding Tokens

Christopher Clark, Yue Yang, Jae Sung Park +8

Grounding has become a fundamental capability of vision-language models (VLMs). Most existing VLMs point by generating coordinates as part of their text output, which requires lear…

Synthetic Visual Genome 2: Extracting Large-scale Spatio-Temporal Scene Graphs from Videos

Ziqi Gao, Jieyu Zhang, Wisdom Oluchi Ikezogwo +10

We introduce Synthetic Visual Genome 2 (SVG2), a large-scale panoptic video scene graph dataset. SVG2 contains over 636K videos with 6.6M objects, 52.0M attributes, and 6.7M relati…

Molmo2: Open Weights and Data for Vision-Language Models with Video Understanding and Grounding

Christopher Clark, Jieyu Zhang, Zixian Ma +18

Today's strongest video-language models (VLMs) remain proprietary. The strongest open-weight models either rely on synthetic data from proprietary VLMs, effectively distilling from…

SAGE: Training Smart Any-Horizon Agents for Long Video Reasoning with Reinforcement Learning

Jitesh Jain, Jialuo Li, Zixian Ma +7

As humans, we are natural any-horizon reasoners, i.e., we can decide whether to iteratively skim long videos or watch short ones in full when necessary for a given task. With this…
