Efficient Context Scaling with LongCat ZigZag Attention

Chen Zhang, Yang Bai, Jiahuan Li +19

We introduce LongCat ZigZag Attention (LoZA), which is a sparse attention scheme designed to transform any existing full-attention models into sparse versions with rather limited c…

Mixture-of-Minds: Multi-Agent Reinforcement Learning for Table Understanding

Yuhang Zhou, Mingrui Zhang, Ke Li +12

Understanding and reasoning over tables is a critical capability for many real-world applications. Large language models (LLMs) have shown promise on this task, but current approac…

HARBOR: Exploring Persona Dynamics in Multi-Agent Competition

Kenan Jiang, Li Xiong, Fei Liu

We investigate factors contributing to LLM agents' success in competitive multi-agent environments, using auctions as a testbed where agents bid to maximize profit. The agents are…

Enhancing Character-Level Understanding in LLMs through Token Internal Structure Learning

Zhu Xu, Zhiqiang Zhao, Zihan Zhang +6

Tokenization methods like Byte-Pair Encoding (BPE) enhance computational efficiency in large language models (LLMs) but often obscure internal character structures within tokens. T…
