Online Video Agent Harness for Long Video Understanding

This work presents VideoXAgent, a purely online video-agent harness for long video understanding that starts from the given video file and user query, plans and decomposes the task, invokes specialized expert tools on demand, and aggregates multimodal evidence to produce a final answer while resolving conflicts among o...

CoFiE: Coarse-to-Fine Evidence Selection for Efficient Streaming Video Understanding

Streaming video understanding requires Vision Language Models (VLLMs) to process growing video streams and answer user questions under tight latency constraints. Existing methods improve efficiency through token pruning and memory-bank schemes, but mainly reduce visual tokens after visual encoding. Consequently, downst...

KV-Skill: Forging Expertise in the Model's Native Language

KV-Skill is introduced, a design space of external factorized operators that a frozen language model reads through a lightweight interface that shows that task knowledge can be acquired from text or experience, compressed into an external operator, and deployed separately from the backbone.

MOSS-VL Technical Report

We present MOSS-VL, an open vision-language model family that treats real-time interaction -- perceiving while it speaks -- as a first-class capability. It is co-designed across the stack: the language decoder attends to vision only through gated cross-attention, so the model can naturally see incoming frames while gen...
