Fewer Tokens, Smaller Cache: Reward-Coordinated Efficient Reasoning

Qiyuan Zhu, Dezhi Li, Pengyu Cheng +8

Large Reasoning Models (LRMs) excel on complex tasks through long chain-of-thought (CoT) reasoning, but their lengthy intermediate steps cause severe overthinking that inflates inf…

Hierarchical Sparse Attention Done Right: Toward Infinite Context Modeling

Xiang Hu, Xinyu Wei, Hao Gu +10

Scaling modern large language models (LLMs) to long contexts is limited by the quadratic computation cost, and poor length extrapolation of dense attention. Chunk-wise sparse atten…

IndexMem: Learned KV-Cache Eviction with Latent Memory for Long-Context LLM Inference

Xintong Yang, Hao Gu, Binxing Xu +6

Large Language Models (LLMs) are increasingly expected to operate over long contexts, yet standard softmax attention incurs a KV cache that grows linearly with sequence length, qui…

Self-Evolving Deep Research via Joint Generation and Evaluation

Han Zhu, Chengkun Cai, Yuanfeng Song +3

Large Language Models (LLMs) have become increasingly adopted in daily applications, with deep research standing out as a particularly important capability. Unlike traditional ques…

RW-TTT: Batched Serving for Request-Owned Test-Time Training State

Jian Yang, Zhizhuo Kou, Yao Tian +4

Test-time training (TTT) adapts an LLM during generation by reading and updating request-owned state, such as fast weights, low-rank deltas, or streaming learner state. This breaks…

When Text Hijacks Vision: Benchmarking and Mitigating Text Overlay-Induced Hallucination in Vision Language Models

Cui Yakun, Xingqun Qi, TianTian Geng +3

Recent advances in Vision-Language Models (VLMs) have substantially enhanced their ability across multimodal video understanding benchmarks spanning temporal, action, object, and s…
