PI-Mem: Pushing Long-Context Reasoning to 3.6M Tokens with Parallel-Iterative Memory

Dawei Liu, Haixu Song, Shuang Cheng +9

Long-context reasoning remains a critical bottleneck for large language models, as recent recurrent-memory approaches face two inherent challenges: sequential chunk-wise updates ca…

MARTI-MARS2: Scaling Multi-Agent Self-Search via Reinforcement Learning for Code Generation

Shijie Wang, Pengfei Li, Yikun Fu +21

While the complex reasoning capability of Large Language Models (LLMs) has attracted significant attention, single-agent systems often encounter inherent performance ceilings in co…
