Distance between Relevant Information Pieces Causes Bias in Long-Context LLMs

ACL 2025finding

Positional bias in large language models hinders their ability to effectively process long inputs. A prominent example is the “lost in the middle” phenomenon, where LLMs struggle to utilize relevant information situated in the middle of the input. While prior research primarily focuses on single pie…

Generalizing Experience for Language Agents with Hierarchical MetaFlows

NeurIPS 2025poster

Recent efforts to employ large language models (LLMs) as agents have demonstrated promising results in a wide range of multi-step agent tasks. However, existing agents lack an effective experience reuse approach to leverage historical completed tasks. In this paper, we propose a novel experience reu…

Proactive Agent: Shifting LLM Agents from Reactive Responses to Active Assistance

ICLR 2025poster

Agents powered by large language models have shown remarkable abilities in solving complex tasks. However, most agent systems remain reactive, limiting their effectiveness in scenarios requiring foresight and autonomous decision-making. In this paper, we tackle the challenge of developing proactive…

DebugBench: Evaluating Debugging Capability of Large Language Models

ACL 2024findings

Large Language Models (LLMs) have demonstrated exceptional coding capability. However, as another critical component of programming proficiency, the debugging capability of LLMs remains relatively unexplored. Previous evaluations of LLMs’ debugging ability are significantly limited by the risk of da…

RepoAgent: An LLM-Powered Open-Source Framework for Repository-level Code Documentation Generation

EMNLP 2024system demonstrations

Generative models have demonstrated considerable potential in software engineering, particularly in tasks such as code generation and debugging. However, their utilization in the domain of code documentation generation remains underexplored. To this end, we introduce RepoAgent, a large language mode…
