DocDancer: Towards Agentic Document-Grounded Information Seeking

Intermediate
Qintong Zhang, Xinjie Lv et al.Jan 8arXiv

DocDancer is a smart document helper that answers questions by exploring and reading long, mixed-media PDFs using just two tools: Search and Read.

VerseCrafter: Dynamic Realistic Video World Model with 4D Geometric Control

Intermediate
Sixiao Zheng, Minghao Yin et al.Jan 8arXiv

VerseCrafter is a video world model that lets you steer both the camera and multiple moving objects by editing a single 4D world state.

Token-Level LLM Collaboration via FusionRoute

Intermediate
Nuoya Xiong, Yuhang Zhou et al.Jan 8arXiv

Big all-in-one language models are powerful but too expensive to run everywhere, while small specialists are cheaper but narrow.

Learnable Multipliers: Freeing the Scale of Language Model Matrix Layers

Intermediate
Maksim Velikanov, Ilyas Chahed et al.Jan 8arXiv

The paper shows that big language models often get stuck with weight sizes set by training hyperparameters instead of by the data, which quietly hurts performance.

SmartSearch: Process Reward-Guided Query Refinement for Search Agents

Intermediate
Tongyu Wen, Guanting Dong et al.Jan 8arXiv

SmartSearch teaches search agents to fix their own bad search queries while they are thinking, not just their final answers.

DR-LoRA: Dynamic Rank LoRA for Mixture-of-Experts Adaptation

Intermediate
Guanzhi Deng, Bo Li et al.Jan 8arXiv

Mixture-of-Experts (MoE) models use many small specialist networks and only activate a few per token, but classic LoRA fine-tuning gives every expert the same rank, wasting parameters on the wrong experts.

AgentOCR: Reimagining Agent History via Optical Self-Compression

Intermediate
Lang Feng, Fuchao Yang et al.Jan 8arXiv

AgentOCR turns an agent’s long text history into pictures so it can remember more using fewer tokens.

#AgentOCR#optical self-compression#visual tokens

AT$^2$PO: Agentic Turn-based Policy Optimization via Tree Search

Intermediate
Zefang Zong, Dingwei Chen et al.Jan 8arXiv

AT2PO is a new way to train AI agents that work in several turns, like asking the web a question, reading the result, and trying again.

#Agentic Reinforcement Learning#Turn-level Optimization#Tree Search

KnowMe-Bench: Benchmarking Person Understanding for Lifelong Digital Companions

Intermediate
Tingyu Wu, Zhisheng Chen et al.Jan 8arXiv

KnowMe-Bench is a new test that checks if AI helpers truly understand a person, not just remember facts.

#person understanding#autobiographical narratives#cognitive stream

Memory Matters More: Event-Centric Memory as a Logic Map for Agent Searching and Reasoning

Intermediate
Yuyang Hu, Jiongnan Liu et al.Jan 8arXiv

This paper turns an AI agent’s memory from a flat list of notes into a logic map of events connected by cause-and-time links.

Qwen3-VL-Embedding and Qwen3-VL-Reranker: A Unified Framework for State-of-the-Art Multimodal Retrieval and Ranking

Intermediate
Mingxin Li, Yanzhao Zhang et al.Jan 8arXiv

This paper builds two teamwork models, Qwen3-VL-Embedding and Qwen3-VL-Reranker, that understand text, images, visual documents, and videos in one shared space so search works across all of them.

#multimodal retrieval#unified embedding space#cross-encoder reranker

TourPlanner: A Competitive Consensus Framework with Constraint-Gated Reinforcement Learning for Travel Planning

Intermediate
Yinuo Wang, Mining Tan et al.Jan 8arXiv

TourPlanner is a travel-planning system that first gathers the right places, then lets multiple expert ‘voices’ debate plans, and finally polishes the winner with a learning method that follows rules before style.
