AgentLongBench: A Controllable Long Benchmark For Long-Contexts Agents via Environment Rollouts

Shicheng Fang, Yuxin Wang, Xiaoran Liu +6

The evolution of Large Language Models (LLMs) into autonomous agents necessitates the management of extensive, dynamic contexts. Current benchmarks, however, remain largely static,…

DiRL: An Efficient Post-Training Framework for Diffusion Language Models

Ying Zhu, Jiaxin Wan, Xiaoran Liu +7

Diffusion Language Models (dLLMs) have emerged as promising alternatives to Auto-Regressive (AR) models. While recent efforts have validated their pre-training potential and accele…

Beyond Real: Imaginary Extension of Rotary Position Embeddings for Long-Context LLMs

Xiaoran Liu, Yuerong Song, Zhigeng Liu +6

Rotary Position Embeddings (RoPE) have become a standard for encoding sequence order in Large Language Models (LLMs) by applying rotations to query and key vectors in the complex p…

SIM-CoT: Supervised Implicit Chain-of-Thought

Xilin Wei, Xiaoran Liu, Yuhang Zang +5

Implicit Chain-of-Thought (CoT) methods offer a token-efficient alternative to explicit CoT reasoning in Large Language Models (LLMs), but a persistent performance gap has limited…

Sparse-dLLM: Accelerating Diffusion LLMs with Dynamic Cache Eviction

Yuerong Song, Xiaoran Liu, Ruixiao Li +5

Diffusion Large Language Models (dLLMs) enable breakthroughs in reasoning and parallel decoding but suffer from prohibitive quadratic computational complexity and memory overhead d…
