Position: Multi-Agent Systems Should Prioritize Concurrency Control

Xin Yang, Letian Li, Zimo Ji +2

LLM-based multi-agent systems (MAS) promise scalable collaboration, yet adding agents often reduces reliability. This position paper argues that many MAS failures are fundamentally…

HDSL: A Hierarchical Domain-Specific Language for Structured 3D Indoor Scene Generation and Localized Editing with LLM Agents

Letian Li, Chao Shen, Shuzhao Xie +6

Text-driven indoor scene generation and editing require an intermediate representation that language models can both produce and revise. Existing LLM-based systems often rely on sc…

cMoLLM at Scale: Horizontal Scaling Laws for Mixture-of-LLMs

Xin Yang, Yemin Wang, Mingda Liu +4

Scaling large language models (LLMs) has driven their success, yet dense Transformers couple capacity and computation: every parameter is activated for every token, making training…
